+## File Input Handling
+
+When your block accepts file uploads, use the basic/advanced mode pattern with `normalizeFileInput`.
+
+### Basic/Advanced File Pattern
+
+```typescript
+// Basic mode: Visual file upload
+{
+  id: 'uploadFile',
+  title: 'File',
+  type: 'file-upload',
+  canonicalParamId: 'file',  // Both map to 'file' param
+  placeholder: 'Upload file',
+  mode: 'basic',
+  multiple: false,
+  required: true,
+  condition: { field: 'operation', value: 'upload' },
+},
+// Advanced mode: Reference from other blocks
+{
+  id: 'fileRef',
+  title: 'File',
+  type: 'short-input',
+  canonicalParamId: 'file',  // Both map to 'file' param
+  placeholder: 'Reference file (e.g., {{file_block.output}})',
+  mode: 'advanced',
+  required: true,
+  condition: { field: 'operation', value: 'upload' },
+},
+```
+
+**Critical constraints:**
+- `canonicalParamId` must NOT match any subblock's `id` in the same block
+- Values are stored under subblock `id`, not `canonicalParamId`
+
+### Normalizing File Input in tools.config
+
+Use `normalizeFileInput` to handle all input variants:
+
+```typescript
+import { normalizeFileInput } from '@/blocks/utils'
+
+tools: {
+  access: ['service_upload'],
+  config: {
+    tool: (params) => {
+      // Check all field IDs: uploadFile (basic), fileRef (advanced), fileContent (legacy)
+      const normalizedFile = normalizeFileInput(
+        params.uploadFile || params.fileRef || params.fileContent,
+        { single: true }
+      )
+      if (normalizedFile) {
+        params.file = normalizedFile
+      }
+      return `service_${params.operation}`
+    },
+  },
+}
+```
+
+**Why this pattern?**
+- Values come through as `params.uploadFile` or `params.fileRef` (the subblock IDs)
+- `canonicalParamId` only controls UI/schema mapping, not runtime values
+- `normalizeFileInput` handles JSON strings from advanced mode template resolution
+
+### File Input Types in `inputs`
+
+Use `type: 'json'` for file inputs:
+
+```typescript
+inputs: {
+  uploadFile: { type: 'json', description: 'Uploaded file (UserFile)' },
+  fileRef: { type: 'json', description: 'File reference from previous block' },
+  // Legacy field for backwards compatibility
+  fileContent: { type: 'string', description: 'Legacy: base64 encoded content' },
+}
+```
+
+### Multiple Files
+
+For multiple file uploads:
+
+```typescript
+{
+  id: 'attachments',
+  title: 'Attachments',
+  type: 'file-upload',
+  multiple: true,  // Allow multiple files
+  maxSize: 25,     // Max size in MB per file
+  acceptedTypes: 'image/*,application/pdf,.doc,.docx',
+}
+
+// In tools.config:
+const normalizedFiles = normalizeFileInput(
+  params.attachments || params.attachmentRefs,
+  // No { single: true } - returns array
+)
+if (normalizedFiles) {
+  params.files = normalizedFiles
+}
+```
+

-## Common Gotchas
+## File Handling
+
+When your integration handles file uploads or downloads, follow these patterns to work with `UserFile` objects consistently.
+
+### What is a UserFile?
+
+A `UserFile` is the standard file representation in Sim:
+
+```typescript
+interface UserFile {
+  id: string       // Unique identifier
+  name: string     // Original filename
+  url: string      // Presigned URL for download
+  size: number     // File size in bytes
+  type: string     // MIME type (e.g., 'application/pdf')
+  base64?: string  // Optional base64 content (if small file)
+  key?: string     // Internal storage key
+  context?: object // Storage context metadata
+}
+```
+
+### File Input Pattern (Uploads)
+
+For tools that accept file uploads, **always route through an internal API endpoint** rather than calling external APIs directly. This ensures proper file content retrieval.
+
+#### 1. Block SubBlocks for File Input
+
+Use the basic/advanced mode pattern:
+
+```typescript
+// Basic mode: File upload UI
+{
+  id: 'uploadFile',
+  title: 'File',
+  type: 'file-upload',
+  canonicalParamId: 'file',  // Maps to 'file' param
+  placeholder: 'Upload file',
+  mode: 'basic',
+  multiple: false,
+  required: true,
+  condition: { field: 'operation', value: 'upload' },
+},
+// Advanced mode: Reference from previous block
+{
+  id: 'fileRef',
+  title: 'File',
+  type: 'short-input',
+  canonicalParamId: 'file',  // Same canonical param
+  placeholder: 'Reference file (e.g., {{file_block.output}})',
+  mode: 'advanced',
+  required: true,
+  condition: { field: 'operation', value: 'upload' },
+},
+```
+
+**Critical:** `canonicalParamId` must NOT match any subblock `id`.
+
+#### 2. Normalize File Input in Block Config
+
+In `tools.config.tool`, use `normalizeFileInput` to handle all input variants:
+
+```typescript
+import { normalizeFileInput } from '@/blocks/utils'
+
+tools: {
+  config: {
+    tool: (params) => {
+      // Normalize file from basic (uploadFile), advanced (fileRef), or legacy (fileContent)
+      const normalizedFile = normalizeFileInput(
+        params.uploadFile || params.fileRef || params.fileContent,
+        { single: true }
+      )
+      if (normalizedFile) {
+        params.file = normalizedFile
+      }
+      return `{service}_${params.operation}`
+    },
+  },
+}
+```
+
+#### 3. Create Internal API Route
+
+Create `apps/sim/app/api/tools/{service}/{action}/route.ts`:
+
+```typescript
+import { createLogger } from '@sim/logger'
+import { NextResponse, type NextRequest } from 'next/server'
+import { z } from 'zod'
+import { checkInternalAuth } from '@/lib/auth/hybrid'
+import { generateRequestId } from '@/lib/core/utils/request'
+import { FileInputSchema, type RawFileInput } from '@/lib/uploads/utils/file-schemas'
+import { processFilesToUserFiles } from '@/lib/uploads/utils/file-utils'
+import { downloadFileFromStorage } from '@/lib/uploads/utils/file-utils.server'
+
+const logger = createLogger('{Service}UploadAPI')
+
+const RequestSchema = z.object({
+  accessToken: z.string(),
+  file: FileInputSchema.optional().nullable(),
+  // Legacy field for backwards compatibility
+  fileContent: z.string().optional().nullable(),
+  // ... other params
+})
+
+export async function POST(request: NextRequest) {
+  const requestId = generateRequestId()
+
+  const authResult = await checkInternalAuth(request, { requireWorkflowId: false })
+  if (!authResult.success) {
+    return NextResponse.json({ success: false, error: 'Unauthorized' }, { status: 401 })
+  }
+
+  const body = await request.json()
+  const data = RequestSchema.parse(body)
+
+  let fileBuffer: Buffer
+  let fileName: string
+
+  // Prefer UserFile input, fall back to legacy base64
+  if (data.file) {
+    const userFiles = processFilesToUserFiles([data.file as RawFileInput], requestId, logger)
+    if (userFiles.length === 0) {
+      return NextResponse.json({ success: false, error: 'Invalid file' }, { status: 400 })
+    }
+    const userFile = userFiles[0]
+    fileBuffer = await downloadFileFromStorage(userFile, requestId, logger)
+    fileName = userFile.name
+  } else if (data.fileContent) {
+    // Legacy: base64 string (backwards compatibility)
+    fileBuffer = Buffer.from(data.fileContent, 'base64')
+    fileName = 'file'
+  } else {
+    return NextResponse.json({ success: false, error: 'File required' }, { status: 400 })
+  }
+
+  // Now call external API with fileBuffer
+  const response = await fetch('https://api.{service}.com/upload', {
+    method: 'POST',
+    headers: { Authorization: `Bearer ${data.accessToken}` },
+    body: new Uint8Array(fileBuffer),  // Convert Buffer for fetch
+  })
+
+  // ... handle response
+}
+```
+
+#### 4. Update Tool to Use Internal Route
+
+```typescript
+export const {service}UploadTool: ToolConfig<Params, Response> = {
+  id: '{service}_upload',
+  // ...
+  params: {
+    file: { type: 'file', required: false, visibility: 'user-or-llm' },
+    fileContent: { type: 'string', required: false, visibility: 'hidden' }, // Legacy
+  },
+  request: {
+    url: '/api/tools/{service}/upload',  // Internal route
+    method: 'POST',
+    body: (params) => ({
+      accessToken: params.accessToken,
+      file: params.file,
+      fileContent: params.fileContent,
+    }),
+  },
+}
+```
+
+### File Output Pattern (Downloads)
+
+For tools that return files, use `FileToolProcessor` to store files and return `UserFile` objects.
+
+#### In Tool transformResponse
+
+```typescript
+import { FileToolProcessor } from '@/executor/utils/file-tool-processor'
+
+transformResponse: async (response, context) => {
+  const data = await response.json()
+
+  // Process file outputs to UserFile objects
+  const fileProcessor = new FileToolProcessor(context)
+  const file = await fileProcessor.processFileData({
+    data: data.content,      // base64 or buffer
+    mimeType: data.mimeType,
+    filename: data.filename,
+  })
+
+  return {
+    success: true,
+    output: { file },
+  }
+}
+```
+
+#### In API Route (for complex file handling)
+
+```typescript
+// Return file data that FileToolProcessor can handle
+return NextResponse.json({
+  success: true,
+  output: {
+    file: {
+      data: base64Content,
+      mimeType: 'application/pdf',
+      filename: 'document.pdf',
+    },
+  },
+})
+```

+
+Sim makes it easy to work with files throughout your workflows. Blocks can receive files, process them, and pass them to other blocks seamlessly.
+
+## File Objects
+
+When blocks output files (like Gmail attachments, generated images, or parsed documents), they return a standardized file object:
+
+```json
+{
+  "name": "report.pdf",
+  "url": "https://...",
+  "base64": "JVBERi0xLjQK...",
+  "type": "application/pdf",
+  "size": 245678
+}
+```
+
+You can access any of these properties when referencing files from previous blocks.
+
+## The File Block
+
+The **File block** is the universal entry point for files in your workflows. It accepts files from any source and outputs standardized file objects that work with all integrations.
+
+**Inputs:**
+- **Uploaded files** - Drag and drop or select files directly
+- **External URLs** - Any publicly accessible file URL
+- **Files from other blocks** - Pass files from Gmail attachments, Slack downloads, etc.
+
+**Outputs:**
+- A list of `UserFile` objects with consistent structure (`name`, `url`, `base64`, `type`, `size`)
+- `combinedContent` - Extracted text content from all files (for documents)
+
+**Example usage:**
+
+```
+// Get all files from the File block
+<file.files>
+
+// Get the first file
+<file.files[0]>
+
+// Get combined text content from parsed documents
+<file.combinedContent>
+```
+
+The File block automatically:
+- Detects file types from URLs and extensions
+- Extracts text from PDFs, CSVs, and documents
+- Generates base64 encoding for binary files
+- Creates presigned URLs for secure access
+
+Use the File block when you need to normalize files from different sources before passing them to other blocks like Vision, STT, or email integrations.
+
+## Passing Files Between Blocks
+
+Reference files from previous blocks using the tag dropdown. Click in any file input field and type `<` to see available outputs.
+
+**Common patterns:**
+
+```
+// Single file from a block
+<gmail.attachments[0]>
+
+// Pass the whole file object
+<file_parser.files[0]>
+
+// Access specific properties
+<gmail.attachments[0].name>
+<gmail.attachments[0].base64>
+```
+
+Most blocks accept the full file object and extract what they need automatically. You don't need to manually extract `base64` or `url` in most cases.
+
+## Triggering Workflows with Files
+
+When calling a workflow via API that expects file input, include files in your request:
+
+<Tabs items={['Base64', 'URL']}>
+  <Tab value="Base64">
+    ```bash
+    curl -X POST "https://sim.ai/api/workflows/YOUR_WORKFLOW_ID/execute" \
+      -H "Content-Type: application/json" \
+      -H "x-api-key: YOUR_API_KEY" \
+      -d '{
+        "document": {
+          "name": "report.pdf",
+          "base64": "JVBERi0xLjQK...",
+          "type": "application/pdf"
+        }
+      }'
+    ```
+  </Tab>
+  <Tab value="URL">
+    ```bash
+    curl -X POST "https://sim.ai/api/workflows/YOUR_WORKFLOW_ID/execute" \
+      -H "Content-Type: application/json" \
+      -H "x-api-key: YOUR_API_KEY" \
+      -d '{
+        "document": {
+          "name": "report.pdf",
+          "url": "https://example.com/report.pdf",
+          "type": "application/pdf"
+        }
+      }'
+    ```
+  </Tab>
+</Tabs>
+
+The workflow's Start block should have an input field configured to receive the file parameter.
+
+## Receiving Files in API Responses
+
+When a workflow outputs files, they're included in the response:
+
+```json
+{
+  "success": true,
+  "output": {
+    "generatedFile": {
+      "name": "output.png",
+      "url": "https://...",
+      "base64": "iVBORw0KGgo...",
+      "type": "image/png",
+      "size": 34567
+    }
+  }
+}
+```
+
+Use `url` for direct downloads or `base64` for inline processing.
+
+## Blocks That Work with Files
+
+**File inputs:**
+- **File** - Parse documents, images, and text files
+- **Vision** - Analyze images with AI models
+- **Mistral Parser** - Extract text from PDFs
+
+**File outputs:**
+- **Gmail** - Email attachments
+- **Slack** - Downloaded files
+- **TTS** - Generated audio files
+- **Video Generator** - Generated videos
+- **Image Generator** - Generated images
+
+**File storage:**
+- **Supabase** - Upload/download from storage
+- **S3** - AWS S3 operations
+- **Google Drive** - Drive file operations
+- **Dropbox** - Dropbox file operations
+
+<Callout type="info">
+  Files are automatically available to downstream blocks. The execution engine handles all file transfer and format conversion.
+</Callout>
+
+## Best Practices
+
+1. **Use file objects directly** - Pass the full file object rather than extracting individual properties. Blocks handle the conversion automatically.
+
+2. **Check file types** - Ensure the file type matches what the receiving block expects. The Vision block needs images, the File block handles documents.
+
+3. **Consider file size** - Large files increase execution time. For very large files, consider using storage blocks (S3, Supabase) for intermediate storage.
