# Adding Integrations

## Overview

Adding a new integration typically requires:
1. **Tools** - API operations (`tools/{service}/`)
2. **Block** - UI component (`blocks/blocks/{service}.ts`)
3. **Icon** - SVG icon (`components/icons.tsx`)
4. **Trigger** (optional) - Webhooks/polling (`triggers/{service}/`)

Always look up the service's API docs first.

## 1. Tools (`tools/{service}/`)

```
tools/{service}/
├── index.ts           # Export all tools
├── types.ts           # Params/response types
├── {action}.ts        # Individual tool (e.g., send_message.ts)
└── ...
```

**Tool file structure:**

```typescript
// tools/{service}/{action}.ts
import type { {Service}Params, {Service}Response } from '@/tools/{service}/types'
import type { ToolConfig } from '@/tools/types'

export const {service}{Action}Tool: ToolConfig<{Service}Params, {Service}Response> = {
  id: '{service}_{action}',
  name: '{Service} {Action}',
  description: 'What this tool does',
  version: '1.0.0',
  oauth: { required: true, provider: '{service}' }, // if OAuth
  params: { /* param definitions */ },
  request: {
    url: '/api/tools/{service}/{action}',
    method: 'POST',
    headers: () => ({ 'Content-Type': 'application/json' }),
    body: (params) => ({ ...params }),
  },
  transformResponse: async (response) => {
    const data = await response.json()
    if (!data.success) throw new Error(data.error)
    return { success: true, output: data.output }
  },
  outputs: { /* output definitions */ },
}
```

**Register in `tools/registry.ts`:**

```typescript
import { {service}{Action}Tool } from '@/tools/{service}'
// Add to registry object
{service}_{action}: {service}{Action}Tool,
```

## 2. Block (`blocks/blocks/{service}.ts`)

```typescript
import { {Service}Icon } from '@/components/icons'
import type { BlockConfig } from '@/blocks/types'
import type { {Service}Response } from '@/tools/{service}/types'

export const {Service}Block: BlockConfig<{Service}Response> = {
  type: '{service}',
  name: '{Service}',
  description: 'Short description',
  longDescription: 'Detailed description',
  category: 'tools',
  bgColor: '#hexcolor',
  icon: {Service}Icon,
  subBlocks: [ /* see SubBlock Properties below */ ],
  tools: {
    access: ['{service}_{action}', ...],
    config: {
      tool: (params) => `{service}_${params.operation}`,
      params: (params) => ({ ...params }),
    },
  },
  inputs: { /* input definitions */ },
  outputs: { /* output definitions */ },
}
```

### SubBlock Properties

```typescript
{
  id: 'fieldName',           // Unique identifier
  title: 'Field Label',      // UI label
  type: 'short-input',       // See SubBlock Types below
  placeholder: 'Hint text',
  required: true,            // See Required below
  condition: { ... },        // See Condition below
  dependsOn: ['otherField'], // See DependsOn below
  mode: 'basic',             // 'basic' | 'advanced' | 'both' | 'trigger'
}
```

**SubBlock Types:** `short-input`, `long-input`, `dropdown`, `code`, `switch`, `slider`, `oauth-input`, `channel-selector`, `user-selector`, `file-upload`, etc.

### `condition` - Show/hide based on another field

```typescript
// Show when operation === 'send'
condition: { field: 'operation', value: 'send' }

// Show when operation is 'send' OR 'read'
condition: { field: 'operation', value: ['send', 'read'] }

// Show when operation !== 'send'
condition: { field: 'operation', value: 'send', not: true }

// Complex: NOT in list AND another condition
condition: {
  field: 'operation',
  value: ['list_channels', 'list_users'],
  not: true,
  and: { field: 'destinationType', value: 'dm', not: true }
}
```

### `required` - Field validation

```typescript
// Always required
required: true

// Conditionally required (same syntax as condition)
required: { field: 'operation', value: 'send' }
```

### `dependsOn` - Clear field when dependencies change

```typescript
// Clear when credential changes
dependsOn: ['credential']

// Clear when authMethod changes AND (credential OR botToken) changes
dependsOn: { all: ['authMethod'], any: ['credential', 'botToken'] }
```

### `mode` - When to show field

- `'basic'` - Only in basic mode (default UI)
- `'advanced'` - Only in advanced mode (manual input)
- `'both'` - Show in both modes (default)
- `'trigger'` - Only when block is used as trigger

**Register in `blocks/registry.ts`:**

```typescript
import { {Service}Block } from '@/blocks/blocks/{service}'
// Add to registry object (alphabetically)
{service}: {Service}Block,
```

## 3. Icon (`components/icons.tsx`)

```typescript
export function {Service}Icon(props: SVGProps<SVGSVGElement>) {
  return (
    <svg {...props} viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
      {/* SVG path from service's brand assets */}
    </svg>
  )
}
```

## 4. Trigger (`triggers/{service}/`) - Optional

```
triggers/{service}/
├── index.ts           # Export all triggers
├── webhook.ts         # Webhook handler
├── utils.ts           # Shared utilities
└── {event}.ts         # Specific event handlers
```

**Register in `triggers/registry.ts`:**

```typescript
import { {service}WebhookTrigger } from '@/triggers/{service}'
// Add to TRIGGER_REGISTRY
{service}_webhook: {service}WebhookTrigger,
```

## Checklist

- [ ] Look up API docs for the service
- [ ] Create `tools/{service}/types.ts` with proper types
- [ ] Create tool files for each operation
- [ ] Create `tools/{service}/index.ts` barrel export
- [ ] Register tools in `tools/registry.ts`
- [ ] Add icon to `components/icons.tsx`
- [ ] Create block in `blocks/blocks/{service}.ts`
- [ ] Register block in `blocks/registry.ts`
- [ ] (Optional) Create triggers in `triggers/{service}/`
- [ ] (Optional) Register triggers in `triggers/registry.ts`
