+import { Step, Steps } from 'fumadocs-ui/components/steps'

+import { Card, Cards } from 'fumadocs-ui/components/card'
+import { ThemeImage } from '@/components/ui/theme-image'
+
+The Webhook Trigger block allows external services to trigger your workflow execution through HTTP webhooks. Unlike starter blocks, webhook triggers are pure input sources that start workflows without requiring manual intervention.
+
+<ThemeImage
+  lightSrc="/static/light/webhooktrigger-light.png"

+  alt="Webhook Trigger Block"

+  height={175}
+/>
+
+<Callout>
+  Webhook triggers cannot receive incoming connections and do not expose webhook data to the workflow. They serve as pure execution triggers.
+</Callout>
+
+## Overview
+
+The Webhook Trigger block enables you to:
+
+<Steps>
+  <Step>
+    <strong>Receive external triggers</strong>: Accept HTTP requests from external services
+  </Step>
+  <Step>
+    <strong>Support multiple providers</strong>: Handle webhooks from Slack, Gmail, GitHub, and more
+  </Step>
+  <Step>
+    <strong>Start workflows automatically</strong>: Execute workflows without manual intervention
+  </Step>
+  <Step>
+    <strong>Provide secure endpoints</strong>: Generate unique webhook URLs for each trigger
+  </Step>
+</Steps>
+
+## How It Works
+
+The Webhook Trigger block operates as a pure input source:
+
+1. **Generate Endpoint** - Creates a unique webhook URL when configured
+2. **Receive Request** - Accepts HTTP POST requests from external services
+3. **Trigger Execution** - Starts the workflow when a valid request is received
+
+## Configuration Options
+
+### Webhook Provider
+
+Choose from supported service providers:
+
+<Cards>
+  <Card title="Slack" href="#">
+    Receive events from Slack apps and bots
+  </Card>
+  <Card title="Gmail" href="#">
+    Handle email-based triggers and notifications
+  </Card>
+  <Card title="Airtable" href="#">
+    Respond to database changes
+  </Card>
+  <Card title="Telegram" href="#">
+    Process bot messages and updates
+  </Card>
+  <Card title="WhatsApp" href="#">
+    Handle messaging events
+  </Card>
+  <Card title="GitHub" href="#">
+    Process repository events and pull requests
+  </Card>
+  <Card title="Discord" href="#">
+    Respond to Discord server events
+  </Card>
+  <Card title="Stripe" href="#">
+    Handle payment and subscription events
+  </Card>
+</Cards>
+
+### Generic Webhooks
+
+For custom integrations or services not listed above, use the **Generic** provider. This option accepts HTTP POST requests from any client and provides flexible authentication options:
+
+- **Optional Authentication** - Configure Bearer token or custom header authentication
+- **IP Restrictions** - Limit access to specific IP addresses
+- **Request Deduplication** - Automatic duplicate request detection using content hashing
+- **Flexible Headers** - Support for custom authentication header names
+
+The Generic provider is ideal for internal services, custom applications, or third-party tools that need to trigger workflows via standard HTTP requests.
+
+### Webhook Configuration
+
+Configure provider-specific settings:
+
+- **Webhook URL** - Automatically generated unique endpoint
+- **Provider Settings** - Authentication and validation options
+- **Security** - Built-in rate limiting and provider-specific authentication
+
+## Best Practices
+
+- **Use unique webhook URLs** for each integration to maintain security
+- **Configure proper authentication** when supported by the provider
+- **Keep workflows independent** of webhook payload structure
+- **Test webhook endpoints** before deploying to production
+- **Monitor webhook delivery** through provider dashboards

+description: How to reference data between blocks in YAML workflows
+---
+
+import { Callout } from 'fumadocs-ui/components/callout'
+import { Tab, Tabs } from 'fumadocs-ui/components/tabs'
+
+Block references are the foundation of data flow in Sim Studio workflows. Understanding how to correctly reference outputs from one block as inputs to another is essential for building functional workflows.
+
+## Basic Reference Rules
+
+### 1. Use Block Names, Not Block IDs
+
+<Tabs items={['Correct', 'Incorrect']}>
+  <Tab>
+    ```yaml
+    # Block definition
+    email-sender:
+      type: agent
+      name: "Email Generator"
+      # ... configuration
+
+    # Reference the block
+    next-block:
+      inputs:
+        userPrompt: "Process this: <emailgenerator.content>"
+    ```
+  </Tab>
+  <Tab>
+    ```yaml
+    # Block definition
+    email-sender:
+      type: agent
+      name: "Email Generator"
+      # ... configuration
+
+    # ❌ Don't reference by block ID
+    next-block:
+      inputs:
+        userPrompt: "Process this: <email-sender.content>"
+    ```
+  </Tab>
+</Tabs>
+
+### 2. Convert Names to Reference Format
+
+To create a block reference:
+
+1. **Take the block name**: "Email Generator"
+2. **Convert to lowercase**: "email generator" 
+3. **Remove spaces and special characters**: "emailgenerator"
+4. **Add property**: `<emailgenerator.content>`
+
+### 3. Use Correct Properties
+
+Different block types expose different properties:
+
+- **Agent blocks**: `.content` (the AI response)
+- **Function blocks**: `.output` (the return value)
+- **API blocks**: `.output` (the response data)
+- **Tool blocks**: `.output` (the tool result)
+
+## Reference Examples
+
+### Common Block References
+
+```yaml
+# Agent block outputs
+<agentname.content>           # Primary AI response
+<agentname.tokens>            # Token usage information
+<agentname.cost>              # Estimated cost
+<agentname.tool_calls>        # Tool execution details
+
+# Function block outputs  
+<functionname.output>         # Function return value
+<functionname.error>          # Error information (if any)
+
+# API block outputs
+<apiname.output>              # Response data
+<apiname.status>              # HTTP status code
+<apiname.headers>             # Response headers
+
+# Tool block outputs
+<toolname.output>             # Tool execution result
+```
+
+### Multi-Word Block Names
+
+```yaml
+# Block name: "Data Processor 2"
+<dataprocessor2.output>
+
+# Block name: "Email Validation Service"  
+<emailvalidationservice.output>
+
+# Block name: "Customer Info Agent"
+<customerinfoagent.content>
+```
+
+## Special Reference Cases
+
+### Starter Block
+
+<Callout type="warning">
+  The starter block is always referenced as `<start.input>` regardless of its actual name.
+</Callout>
+
+```yaml
+# Starter block definition
+my-custom-start:
+  type: starter
+  name: "Custom Workflow Start"
+  # ... configuration
+
+# Always reference as 'start'
+agent-1:
+  inputs:
+    userPrompt: <start.input>  # ✅ Correct
+    # userPrompt: <customworkflowstart.input>  # ❌ Wrong
+```
+
+### Loop Variables
+
+Inside loop blocks, special variables are available:
+
+```yaml
+# Available in loop child blocks
+<loop.index>          # Current iteration (0-based)
+<loop.currentItem>    # Current item being processed (forEach loops)
+<loop.items>          # Full collection (forEach loops)
+```
+
+### Parallel Variables
+
+Inside parallel blocks, special variables are available:
+
+```yaml
+# Available in parallel child blocks
+<parallel.index>          # Instance number (0-based)
+<parallel.currentItem>    # Item for this instance
+<parallel.items>          # Full collection
+```
+
+## Complex Reference Examples
+
+### Nested Data Access
+
+When referencing complex objects, use dot notation:
+
+```yaml
+# If an agent returns structured data
+data-analyzer:
+  type: agent
+  name: "Data Analyzer"
+  inputs:
+    responseFormat: |
+      {
+        "schema": {
+          "type": "object",
+          "properties": {
+            "analysis": {"type": "object"},
+            "summary": {"type": "string"},
+            "metrics": {"type": "object"}
+          }
+        }
+      }
+
+# Reference nested properties
+next-step:
+  inputs:
+    userPrompt: |
+      Summary: <dataanalyzer.analysis.summary>
+      Score: <dataanalyzer.metrics.score>
+      Full data: <dataanalyzer.content>
+```
+
+### Multiple References in Text
+
+```yaml
+email-composer:
+  type: agent
+  inputs:
+    userPrompt: |
+      Create an email with the following information:
+      
+      Customer: <customeragent.content>
+      Order Details: <orderprocessor.output>
+      Support Ticket: <ticketanalyzer.content>
+      
+      Original request: <start.input>
+```
+
+### References in Code Blocks
+
+When using references in function blocks, they're replaced as JavaScript values:
+
+```yaml
+data-processor:
+  type: function
+  inputs:
+    code: |
+      // References are replaced with actual values
+      const customerData = <customeragent.content>;
+      const orderInfo = <orderprocessor.output>;
+      const originalInput = <start.input>;
+      
+      // Process the data

+
+## Reference Validation
+
+Sim Studio validates all references when importing YAML:
+
+### Valid References
+- Block exists in the workflow
+- Property is appropriate for block type  
+- No circular dependencies
+- Proper syntax formatting
+
+### Common Errors
+- **Block not found**: Referenced block doesn't exist
+- **Wrong property**: Using `.content` on a function block
+- **Typos**: Misspelled block names or properties
+- **Circular references**: Block references itself directly or indirectly
+
+## Best Practices
+
+1. **Use descriptive block names**: Makes references more readable
+2. **Be consistent**: Use the same naming convention throughout
+3. **Check references**: Ensure all referenced blocks exist
+4. **Avoid deep nesting**: Keep reference chains manageable
+5. **Document complex flows**: Add comments to explain reference relationships

+
+## Tool Configuration
+
+Tools are defined as an array where each tool has this structure:
+
+```yaml
+tools:
+  - type: <string>                      # Tool type identifier (exa, gmail, slack, etc.)
+    title: <string>                     # Human-readable display name
+    toolId: <string>                    # Internal tool identifier
+    operation: <string>                 # Tool operation/method name
+    usageControl: <string>              # When AI can use it (auto | required | none)
+    params: <object>                    # Tool-specific configuration parameters
+    isExpanded: <boolean>               # UI state (optional, default: false)
+```
+
+## Connection Configuration
+
+Connections define where the workflow goes based on execution results:
+
+```yaml
+connections:
+  success: <string>                     # Target block ID for successful execution
+  error: <string>                       # Target block ID for error handling (optional)
+```

+
+## Connection Configuration
+
+Connections define where the workflow goes based on request results:
+
+```yaml
+connections:
+  success: <string>                     # Target block ID for successful requests
+  error: <string>                       # Target block ID for error handling (optional)
+```
+
+## Examples
+
+### Simple GET Request
+
+```yaml
+user-api:
+  type: api
+  name: "Fetch User Data"
+  inputs:
+    url: "https://api.example.com/users/123"
+    method: GET
+    headers:
+      - key: "Authorization"
+        value: "Bearer {{API_TOKEN}}"
+      - key: "Content-Type"
+        value: "application/json"
+  connections:
+    success: process-user-data
+    error: handle-api-error
+```
+
+### POST Request with Body
+
+```yaml
+create-ticket:
+  type: api
+  name: "Create Support Ticket"
+  inputs:
+    url: "https://api.support.com/tickets"
+    method: POST
+    headers:
+      - key: "Authorization"
+        value: "Bearer {{SUPPORT_API_KEY}}"
+      - key: "Content-Type"
+        value: "application/json"
+    body: |
+      {
+        "title": "<agent.title>",
+        "description": "<agent.description>",
+        "priority": "high"
+      }
+  connections:
+    success: ticket-created
+    error: ticket-error
+```
+
+### Dynamic URL with Query Parameters
+
+```yaml
+search-api:
+  type: api
+  name: "Search Products"
+  inputs:
+    url: "https://api.store.com/products"
+    method: GET
+    queryParams:
+      - key: "q"
+        value: <start.searchTerm>
+      - key: "limit"
+        value: "10"
+      - key: "category"
+        value: <filter.category>
+    headers:
+      - key: "Authorization"
+        value: "Bearer {{STORE_API_KEY}}"
+  connections:
+    success: display-results
+```
+
+## Output References
+
+After an API block executes, you can reference its outputs:
+
+```yaml
+# In subsequent blocks
+next-block:
+  inputs:
+    data: <api-block-name.output>        # Response data
+    status: <api-block-name.status>      # HTTP status code  
+    headers: <api-block-name.headers>    # Response headers
+    error: <api-block-name.error>        # Error details (if any)
+```
+
+## Best Practices
+
+- Use environment variables for API keys: `{{API_KEY_NAME}}`
+- Include error handling with error connections
+- Set appropriate timeouts for your use case
+- Validate response status codes in subsequent blocks
+- Use meaningful block names for easier reference

+## Connection Configuration
+
+Unlike other blocks, conditions use branching connections based on condition outcomes:
+
+```yaml
+connections:
+  conditions:
+    if: <string>                        # Target block ID when primary condition is true
+    else-if: <string>                   # Target block ID when secondary condition is true (optional)
+    else-if-2: <string>                 # Target block ID when third condition is true (optional)
+    else-if-3: <string>                 # Target block ID when fourth condition is true (optional)
+    # Additional else-if-N connections can be added as needed
+    else: <string>                      # Target block ID when no conditions match (optional)
+```
+
+## Examples
+
+### Simple If-Else
+
+```yaml
+status-check:
+  type: condition
+  name: "Status Check"
+  inputs:
+    conditions:
+      if: <start.status> === "approved"
+      else: true
+  connections:
+    conditions:
+      if: send-approval-email
+      else: send-rejection-email
+```
+
+### Multiple Conditions
+
+```yaml
+user-routing:
+  type: condition
+  name: "User Type Router"
+  inputs:
+    conditions:
+      if: <start.user_type> === "admin"

+      if: admin-dashboard
+      else-if: premium-features
+      else-if-2: basic-features
+      else: registration-flow
+```
+
+### Numeric Comparisons
+
+```yaml
+score-evaluation:
+  type: condition
+  name: "Score Evaluation"
+  inputs:
+    conditions:
+      if: <agent.score> >= 90

+
+## Output References
+
+After an evaluator block executes, you can reference its outputs:
+
+```yaml
+# In subsequent blocks
+next-block:
+  inputs:
+    evaluation: <evaluator-name.content>     # Evaluation summary
+    scores: <evaluator-name.scores>          # Individual metric scores
+    overall: <evaluator-name.overall>        # Overall assessment
+```
+
+## Best Practices
+
+- Define clear, specific evaluation criteria
+- Use appropriate scoring ranges for your use case
+- Choose models with strong reasoning capabilities
+- Use lower temperature for consistent scoring
+- Include detailed metric descriptions
+- Test with diverse content types
+- Consider multiple evaluators for complex assessments

+---
+
+import { Card, Cards } from "fumadocs-ui/components/card";
+
+This section contains the complete YAML schema definitions for all available block types in Sim Studio. Each block type has specific configuration requirements and output formats.
+

+
+## Common Schema Elements
+
+All blocks share these common elements:
+
+### Basic Structure
+
+```yaml
+block-id:
+  type: <block-type>
+  name: <display-name>
+  inputs:
+    # Block-specific configuration
+  connections:
+    # Connection definitions
+```
+
+### Connection Types
+
+- **success**: Target block for successful execution
+- **error**: Target block for error handling (optional)
+- **conditions**: Multiple paths for conditional blocks
+
+### Environment Variables
+
+Use double curly braces for environment variables:
+
+```yaml
+inputs:
+  apiKey: '{{API_KEY_NAME}}'
+  endpoint: '{{SERVICE_ENDPOINT}}'
+```
+
+### Block References
+
+Reference other block outputs using the block name in lowercase:
+
+```yaml
+inputs:
+  userPrompt: <blockname.content>
+  data: <functionblock.output>
+  originalInput: <start.input>
+```
+
+## Validation Rules
+
+All YAML blocks are validated against their schemas:
+
+1. **Required fields**: Must be present
+2. **Type validation**: Values must match expected types
+3. **Enum validation**: String values must be from allowed lists
+4. **Range validation**: Numbers must be within specified ranges
+5. **Pattern validation**: Strings must match regex patterns (where applicable)
+
+## Quick Reference
+
+### Block Types and Properties
+
+| Block Type | Primary Output | Common Use Cases |

+      error:
+        type: string
+        description: Target block ID for error handling
+```
+
+## Connection Configuration
+
+Loop blocks use a special connection format with a `loop` section:
+
+```yaml
+connections:
+  loop:
+    start: <string>                     # Target block ID to execute inside the loop
+    end: <string>                       # Target block ID after loop completion (optional)
+  error: <string>                       # Target block ID for error handling (optional)
+```
+
+Alternative format (legacy):
+```yaml
+connections:
+  success: <string>                     # Target block ID after loop completion
+  error: <string>                       # Target block ID for error handling (optional)
+```
+
+## Child Block Configuration
+
+Blocks inside a loop must have their `parentId` set to the loop block ID:
+
+```yaml
+loop-1:
+  type: loop
+  name: "Process Items"
+  inputs:
+    loopType: forEach
+    collection: <start.items>
+  connections:
+    loop:
+      start: process-item
+      end: final-results
+
+# Child block inside the loop
+process-item:
+  type: agent
+  name: "Process Item"
+  parentId: loop-1                      # References the loop block
+  inputs:
+    systemPrompt: "Process this item"
+    userPrompt: <loop.currentItem>
+    model: gpt-4o
+    apiKey: '{{OPENAI_API_KEY}}'
+```

+  name: "Process Task"
+  parentId: parallel-processing-loop
+  inputs:
+    url: "https://api.example.com/process"
+    method: POST
+    headers:
+      - key: "Authorization"
+        value: "Bearer {{API_TOKEN}}"
+    body: |
+      {
+        "taskId": "<loop.currentItem.id>",
+        "data": "<loop.currentItem.data>"
+      }
+  connections:
+    success: task-completed
+```
+
+## Loop Variables
+
+Inside loop child blocks, these special variables are available:
+
+```yaml
+# Available in all child blocks of the loop
+<loop.index>                    # Current iteration number (0-based)
+<loop.currentItem>              # Current item being processed (forEach loops)
+<loop.items>                    # Full collection (forEach loops)
+```
+
+## Output References
+
+After a loop completes, you can reference its aggregated results:
+
+```yaml
+# In blocks after the loop
+final-processor:
+  inputs:
+    all-results: <loop-name.results>    # Array of all iteration results
+    total-count: <loop-name.count>      # Number of iterations completed
+```
+
+## Best Practices
+
+- Set reasonable iteration limits to avoid long execution times
+- Use forEach for collection processing, for loops for fixed iterations
+- Consider using maxConcurrency for I/O bound operations
+- Include error handling for robust loop execution
+- Use descriptive names for loop child blocks
+- Test with small collections first
+- Monitor execution time for large collections

+      error:
+        type: string
+        description: Target block ID for error handling
+```
+
+## Connection Configuration
+
+Parallel blocks use a special connection format with a `parallel` section:
+
+```yaml
+connections:
+  parallel:
+    start: <string>                     # Target block ID to execute inside each parallel instance
+    end: <string>                       # Target block ID after all instances complete (optional)
+  error: <string>                       # Target block ID for error handling (optional)
+```
+
+Alternative format (legacy):
+```yaml
+connections:
+  success: <string>                     # Target block ID after all instances complete
+  error: <string>                       # Target block ID for error handling (optional)
+```
+
+## Child Block Configuration
+
+Blocks inside a parallel block must have their `parentId` set to the parallel block ID:
+
+```yaml
+parallel-1:
+  type: parallel
+  name: "Process Items"
+  inputs:
+    parallelType: collection
+    collection: <start.items>
+  connections:
+    parallel:
+      start: process-item
+      end: aggregate-results
+
+# Child block inside the parallel
+process-item:
+  type: agent
+  name: "Process Item"
+  parentId: parallel-1                  # References the parallel block
+  inputs:
+    systemPrompt: "Process this item"
+    userPrompt: <parallel.currentItem>
+    model: gpt-4o
+    apiKey: '{{OPENAI_API_KEY}}'
+```
+
+## Examples
+
+### Count-Based Parallel Processing
+
+```yaml

+  type: parallel
+  name: "Worker Parallel"
+  inputs:
+    parallelType: count

+      end: collect-worker-results
+
+worker-task:
+  type: api

+  connections:
+    success: analysis-complete
+```
+
+## Parallel Variables
+
+Inside parallel child blocks, these special variables are available:
+
+```yaml
+# Available in all child blocks of the parallel
+<parallel.index>                # Instance number (0-based)
+<parallel.currentItem>          # Item for this instance (collection type)
+<parallel.items>                # Full collection (collection type)
+```
+
+## Output References
+
+After a parallel block completes, you can reference its aggregated results:
+
+```yaml
+# In blocks after the parallel
+final-processor:
+  inputs:
+    all-results: <parallel-name.results>  # Array of all instance results
+    total-count: <parallel-name.count>    # Number of instances completed
+```
+
+## Best Practices
+
+- Use appropriate maxConcurrency to avoid overwhelming APIs
+- Ensure operations are independent and don't rely on each other
+- Include error handling for robust parallel execution
+- Test with small collections first
+- Monitor rate limits for external APIs
+- Use collection type for distributing work, count type for fixed instances
+- Consider memory usage with large collections

+## Connection Configuration
+
+Response blocks are terminal blocks (no outgoing connections) and define the final output:
+
+```yaml
+# No connections object needed - Response blocks are always terminal
+```
+
+## Examples
+
+### Simple Response
+
+```yaml
+simple-response:
+  type: response
+  name: "Simple Response"

+
+## Connection Configuration
+
+Router blocks use a success array containing all possible routing destinations:
+
+```yaml
+connections:
+  success:
+    - <string>                          # Target block ID option 1
+    - <string>                          # Target block ID option 2
+    - <string>                          # Target block ID option 3
+    # Additional target block IDs as needed
+```
+
+## Examples
+
+### Content Type Router
+
+```yaml
+content-router:
+  type: router
+  name: "Content Type Router"
+  inputs:
+    prompt: |
+      Route this content based on its type:
+      - If it's a question, route to question-handler
+      - If it's a complaint, route to complaint-handler  
+      - If it's feedback, route to feedback-handler
+      - If it's a request, route to request-handler
+      
+      Content: <start.input>
+    model: gpt-4o
+    apiKey: '{{OPENAI_API_KEY}}'
+  connections:
+    success:
+      - question-handler
+      - complaint-handler
+      - feedback-handler
+      - request-handler
+```
+
+### Priority Router
+
+```yaml
+priority-router:
+  type: router
+  name: "Priority Router" 
+  inputs:
+    prompt: |
+      Analyze the urgency and route accordingly:
+      - urgent-queue: High priority, needs immediate attention
+      - standard-queue: Normal priority, standard processing
+      - low-queue: Low priority, can be delayed
+      
+      Email content: <email-analyzer.content>
+      
+      Route based on urgency indicators, deadlines, and tone.
+    model: gpt-4o
+    temperature: 0.2
+    apiKey: '{{OPENAI_API_KEY}}'
+  connections:
+    success:
+      - urgent-queue
+      - standard-queue  
+      - low-queue
+```
+
+### Department Router
+
+```yaml
+department-router:
+  type: router
+  name: "Department Router"
+  inputs:
+    prompt: |
+      Route this customer inquiry to the appropriate department:
+      
+      - sales-team: Sales questions, pricing, demos
+      - support-team: Technical issues, bug reports, how-to questions
+      - billing-team: Payment issues, subscription changes, invoices
+      - general-team: General inquiries, feedback, other topics
+      
+      Customer message: <start.input>
+      Customer type: <customer-analyzer.type>
+    model: claude-3-5-sonnet-20241022
+    apiKey: '{{ANTHROPIC_API_KEY}}'
+  connections:
+    success:
+      - sales-team
+      - support-team
+      - billing-team
+      - general-team
+```
+
+## Advanced Configuration
+
+### Multiple Models Router
+
+```yaml
+model-selector-router:
+  type: router
+  name: "Model Selection Router"
+  inputs:
+    prompt: |
+      Based on the task complexity, route to the appropriate model:
+      - simple-gpt35: Simple questions, basic tasks
+      - advanced-gpt4: Complex analysis, detailed reasoning
+      - specialized-claude: Creative writing, nuanced analysis
+      
+      Task: <start.task>
+      Complexity indicators: <analyzer.complexity>
+    model: gpt-4o-mini
+    temperature: 0.1
+    apiKey: '{{OPENAI_API_KEY}}'
+  connections:
+    success:
+      - simple-gpt35
+      - advanced-gpt4
+      - specialized-claude
+```
+
+## Output References
+
+Router blocks don't produce direct outputs but control workflow path:
+
+```yaml
+# Router decisions affect which subsequent blocks execute
+# Access the routed block's outputs normally:
+final-step:
+  inputs:
+    routed-result: <routed-block-name.content>
+```
+
+## Best Practices
+
+- Provide clear routing criteria in the prompt
+- Use specific, descriptive target block names
+- Include examples of content for each routing path
+- Use lower temperature values for consistent routing
+- Test with diverse input types to ensure accurate routing
+- Consider fallback paths for edge cases

+          "timestamp": "{{new Date().toISOString()}}"
+        }
+  connections:
+    success: route-by-method
+```
+
+## Webhook Variables
+
+Inside webhook-triggered workflows, these special variables are available:
+
+```yaml
+# Available in blocks after the webhook
+<webhook.payload>               # Full request payload/body
+<webhook.headers>               # Request headers
+<webhook.method>                # HTTP method used
+<webhook.query>                 # Query parameters
+<webhook.path>                  # Request path
+<webhook.challenge>             # Challenge parameter (for verification)
+```
+
+## Output References
+
+After a webhook processes a request, you can reference its data:
+
+```yaml
+# In subsequent blocks
+process-webhook:
+  inputs:
+    payload: <webhook-name.payload>      # Request payload
+    headers: <webhook-name.headers>      # Request headers
+    method: <webhook-name.method>        # HTTP method
+```
+
+## Security Best Practices
+
+- Always use webhook secrets for verification
+- Validate expected headers and methods
+- Implement proper error handling
+- Use HTTPS endpoints in production
+- Monitor webhook activity and failures
+- Set appropriate response timeouts
+- Validate payload structure before processing

+    workflowResult: <workflow-name.output>    # Sub-workflow output
+    executionTime: <workflow-name.duration>  # Execution duration
+    status: <workflow-name.status>           # Execution status
+```
+
+## Best Practices
+
+- Use descriptive workflow IDs for clarity
+- Map only necessary data to sub-workflows
+- Set appropriate timeouts for workflow complexity
+- Include error handling for robust execution
+- Pass environment variables securely
+- Test sub-workflows independently first
+- Monitor nested workflow performance
+- Use versioned workflow IDs for stability

+title: YAML Workflow Reference
+description: Complete guide to writing YAML workflows in Sim Studio
+---
+
+import { Card, Cards } from "fumadocs-ui/components/card";
+import { Step, Steps } from "fumadocs-ui/components/steps";
+import { Tab, Tabs } from "fumadocs-ui/components/tabs";
+
+YAML workflows provide a powerful way to define, version, and share workflow configurations in Sim Studio. This reference guide covers the complete YAML syntax, block schemas, and best practices for creating robust workflows.
+
+## Quick Start
+
+Every Sim Studio workflow follows this basic structure:
+
+```yaml
+version: '1.0'
+blocks:
+  start:
+    type: starter
+    name: Start
+    inputs:
+      startWorkflow: manual
+    connections:
+      success: agent-1
+
+  agent-1:
+    type: agent
+    name: "AI Assistant"
+    inputs:
+      systemPrompt: "You are a helpful assistant."
+      userPrompt: 'Hi'
+      model: gpt-4o
+      apiKey: '{{OPENAI_API_KEY}}'
+```
+
+## Core Concepts
+
+<Steps>
+  <Step>
+    <strong>Version Declaration</strong>: Must be exactly `version: '1.0'` (with quotes)
+  </Step>
+  <Step>
+    <strong>Blocks Structure</strong>: All workflow blocks are defined under the `blocks` key
+  </Step>
+  <Step>
+    <strong>Block References</strong>: Use block names in lowercase with spaces removed (e.g., `<aiassistant.content>`)
+  </Step>
+  <Step>
+    <strong>Environment Variables</strong>: Reference with double curly braces `{{VARIABLE_NAME}}`
+  </Step>
+</Steps>
+
+## Block Types
+
+Sim Studio supports several core block types, each with specific YAML schemas:
+
+<Cards>
+  <Card title="Starter Block" href="/yaml/blocks/starter">
+    Workflow entry point with support for manual, webhook, and scheduled triggers
+  </Card>
+  <Card title="Agent Block" href="/yaml/blocks/agent">
+    AI-powered processing with support for tools and structured output
+  </Card>
+  <Card title="Function Block" href="/yaml/blocks/function">
+    Custom JavaScript/TypeScript code execution
+  </Card>
+  <Card title="API Block" href="/yaml/blocks/api">
+    HTTP requests to external services
+  </Card>
+  <Card title="Condition Block" href="/yaml/blocks/condition">
+    Conditional branching based on boolean expressions
+  </Card>
+  <Card title="Router Block" href="/yaml/blocks/router">
+    AI-powered intelligent routing to multiple paths
+  </Card>
+  <Card title="Loop Block" href="/yaml/blocks/loop">
+    Iterative processing with for and forEach loops
+  </Card>
+  <Card title="Parallel Block" href="/yaml/blocks/parallel">
+    Concurrent execution across multiple instances
+  </Card>
+  <Card title="Webhook Block" href="/yaml/blocks/webhook">
+    Webhook triggers for external integrations
+  </Card>
+  <Card title="Evaluator Block" href="/yaml/blocks/evaluator">
+    Validate outputs against defined criteria and metrics
+  </Card>
+  <Card title="Workflow Block" href="/yaml/blocks/workflow">
+    Execute other workflows as reusable components
+  </Card>
+  <Card title="Response Block" href="/yaml/blocks/response">
+    Final workflow output formatting
+  </Card>
+</Cards>
+
+## Block Reference Syntax
+
+The most critical aspect of YAML workflows is understanding how to reference data between blocks:
+
+### Basic Rules
+
+1. **Use the block name** (not the block ID) converted to lowercase with spaces removed
+2. **Add the appropriate property** (.content for agents, .output for tools)
+3. **When using chat, reference the starter block** as `<start.input>`
+
+### Examples
+
+```yaml
+# Block definitions
+email-processor:
+  type: agent
+  name: "Email Agent"
+  # ... configuration
+
+data-formatter:
+  type: function
+  name: "Data Agent"
+  # ... configuration
+
+# Referencing their outputs
+next-block:
+  type: agent
+  name: "Next Step"
+  inputs:
+    userPrompt: |
+      Process this email: <emailagent.content>
+      Use this formatted data: <dataagent.output>
+      Original input: <start.input>
+```
+
+### Special Cases
+
+- **Loop Variables**: `<loop.index>`, `<loop.currentItem>`, `<loop.items>`
+- **Parallel Variables**: `<parallel.index>`, `<parallel.currentItem>`
+
+## Environment Variables
+
+Use environment variables for sensitive data like API keys:
+
+```yaml
+inputs:
+  apiKey: '{{OPENAI_API_KEY}}'
+  database: '{{DATABASE_URL}}'
+  token: '{{SLACK_BOT_TOKEN}}'
+```
+
+## Best Practices
+
+- **Keep block names human-readable**: "Email Processor" for UI display
+- **Reference environment variables**: Never hardcode API keys
+- **Structure for readability**: Group related blocks logically
+- **Test incrementally**: Build workflows step by step
+
+## Next Steps
+
+- [Block Reference Syntax](/yaml/block-reference) - Detailed reference rules
+- [Complete Block Schemas](/yaml/blocks) - All available block types
+- [Workflow Examples](/yaml/examples) - Real-world workflow patterns
