Messaging API

[luandro]

Create a Messaging API that unifies communication with the Simulator, WhatsApp, and ~~Telegram~ into a single, flexible API. This API will act as a central hub for handling incoming and outgoing messages, seamlessly integrating with Trigger.dev and Supabase to manage message processing and storage.

The workflow ensures:

• Incoming messages are saved to the receivedMessages DB.
• Responses are generated by the Plugin API.
• Outgoing messages are saved to the toSendMessages DB and sent back via the API.
• A cyclic design for managing multi-turn conversations effectively.

Tasks

1. API Design

   • Define API endpoints for sending and receiving messages:
     • POST /api/messages/send
     • GET /api/messages/receive
     • GET /api/messages/health
   • Unify Simulator, WhatsApp, and Telegram as part of a single Messaging API.

2. Integration with Trigger.dev and Supabase

   • Trigger.dev:
     • Save incoming messages to the receivedMessages DB.
     • Call the Plugin API to process and generate responses.
     • Save outgoing responses to the toSendMessages DB.
   • Supabase:
     • Set up the receivedMessages DB for storing incoming messages.
     • Set up the toSendMessages DB for tracking outgoing messages.

3. Platform Integrations

   • Simulator:
     • Integrate as a platform for testing automated conversations, see Develop simulator dx #3.
   • WhatsApp:
     • Use WhatsApp Web JS or equivalent library for integration.
     • Support sending and receiving text, images, and other formats.
   • Telegram:
     • Use telegraf or equivalent library for integration.
     • Support sending and receiving text, images, and other formats.

4. Message Processing

   • Develop a cyclic message-handling workflow:
     • Incoming messages → Trigger.dev → Plugin API → Outgoing responses.
     • Ensure responses are routed back to the Messaging API for delivery.
   • Implement robust error handling for message failures or delays.

5. Testing

   • Test the unified API with all platforms (Simulator, WhatsApp, Telegram).
   • Validate that responses follow a cyclic workflow and maintain consistency.
   • Ensure edge cases (e.g., failed deliveries, duplicate messages) are handled effectively.

6. Documentation

   • Write detailed documentation for:
     • API endpoints and usage.
     • Setting up integrations with platforms.
     • Configuring Trigger.dev and Supabase.
     • Workflow overview with examples.

Acceptance Criteria

• The Messaging API integrates seamlessly with Trigger.dev, Supabase, and platforms.
• Incoming and outgoing messages follow the cyclic workflow effectively.
• Error handling and retry mechanisms are robust and operational.
• Comprehensive documentation covers API usage and platform setup.
