Developer guide introduction

Use the Communications Platform REST APIs to exchange information about messages, contacts, and owners programmatically. Every capability documented in the Communications Platform user guide has a corresponding API endpoint here. Request and response bodies use JSON.

Who this is for

This section is for developers integrating messaging capabilities into their own applications via API.

Before you begin

• Review web programming concepts, including HTTP requests and responses.
• Prepare to send and process JSON data.
• Ask a platform administrator to retrieve an API key for your integration (see Preferences).

Two webhook mechanisms

This platform has two separate webhook-like mechanisms -- use the one that matches your use case:

• Custom Webhook: configured under Communications Platform → Integrations. Routes Live Chat and Chatbot automation events (inbound/outbound messages, session start/end) to an endpoint you control.
• Callback URL WhatsApp Business: configured for your WhatsApp Business Account. Receives Meta's native WhatsApp Business notifications (message delivery status, account status changes) directly from Meta.

See the Communications Platform introduction for the same capabilities via the Workspace UI, no code required.

Chatbot, Live Chat, and Administration Console are configured through their own sections in the platform UI, not through this API — see Chatbot introduction, Live Chat introduction, and Administration Console introduction.
