# WhatsApp Business Automation via Rube MCP

Automate WhatsApp Business operations through Composio's WhatsApp toolkit via Rube MCP.

## Prerequisites

- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
- Active WhatsApp connection via `RUBE_MANAGE_CONNECTIONS` with toolkit `whatsapp`
- Always call `RUBE_SEARCH_TOOLS` first to get current tool schemas
- WhatsApp Business API account required (not regular WhatsApp)

## Setup

**Get Rube MCP**: Add `https://rube.app/mcp` as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.


1. Verify Rube MCP is available by confirming `RUBE_SEARCH_TOOLS` responds
2. Call `RUBE_MANAGE_CONNECTIONS` with toolkit `whatsapp`
3. If connection is not ACTIVE, follow the returned auth link to complete WhatsApp Business setup
4. Confirm connection status shows ACTIVE before running any workflows

## Core Workflows

### 1. Send a Text Message

**When to use**: User wants to send a text message to a WhatsApp contact

**Key parameters**:
- `to`: Recipient phone number in international format (e.g., '+14155551234')
- `body`: Message text content
- `phone_number_id`: Business phone number ID to send from

**Pitfalls**:
- Phone numbers must be in international E.164 format with country code
- Messages outside the 24-hour window require approved templates
- The 24-hour window starts when the customer last messaged you
- Business-initiated conversations require template messages first

### 2. Send Template Messages

**When to use**: User wants to send pre-approved template messages for outbound communication

**Tool sequence**:
1. `WHATSAPP_GET_MESSAGE_TEMPLATES` - List available templates [Prerequisite]
2. `WHATSAPP_GET_TEMPLATE_STATUS` - Check template approval status [Optional]

**Key parameters**:
- `template_name`: Name of the approved template

   OR
3. `WHATSAPP_SEND_MEDIA` - Send media using a public URL [Alternative]

- Media size limits vary by type (images: 5MB, videos: 16MB, documents: 100MB)
- Supported formats: images (JPEG, PNG), videos (MP4, 3GPP), documents (PDF, etc.)
- SEND_MEDIA requires a publicly accessible HTTPS URL

### 4. Reply to Messages

**Tool sequence**:
1. `WHATSAPP_SEND_REPLY` - Send a reply to a specific message [Required]

**Key parameters**:

- `to`: Recipient phone number
- `body`: Reply text content

**Pitfalls**:

- The original message must still exist (not deleted) for the quote to display

### 5. Manage Business Profile and Templates

### 6. Share Contacts

**Tool sequence**:
1. `WHATSAPP_SEND_CONTACTS` - Send contact cards [Required]

**Pitfalls**:
- Contact objects must follow the WhatsApp Business API contact schema

## Common Patterns

### 24-Hour Messaging Window

- Customers must message you first to open a conversation window
- Within 24 hours of their last message, you can send free-form messages
- After 24 hours, only approved template messages can be sent
- Template messages can re-open the conversation window

### Phone Number Resolution

```
1. Call WHATSAPP_GET_PHONE_NUMBERS
2. Extract phone_number_id for your business number
3. Use phone_number_id in all send operations
```

### Media Upload Flow

```
1. Call WHATSAPP_UPLOAD_MEDIA with the file
2. Extract media_id from response
3. Call WHATSAPP_SEND_MEDIA_BY_ID with media_id
4. OR use WHATSAPP_SEND_MEDIA with a public URL directly
```

## Known Pitfalls

**Phone Number Format**:
- Always use E.164 format: +[country code][number] (e.g., '+14155551234')
- Do not include dashes, spaces, or parentheses
- Country code is required; local numbers without it will fail

**Messaging Restrictions**:
- Business-initiated messages require templates outside the 24-hour window
- Template messages cost money per conversation
- Rate limits apply per phone number and per account

**Media Handling**:
- Uploaded media expires; use promptly after upload
- Media URLs must be publicly accessible HTTPS
- Stickers have specific requirements (WebP format, 512x512 pixels)

**Template Management**:
- Template review can take up to 24 hours
- Rejected templates need to be fixed and resubmitted
- Template variables use double curly braces: {{1}}, {{2}}, etc.
