Developer API

Integrate WhatsApp SaaS with your apps using REST API. Send WhatsApp messages and check account info programmatically.

Overview

The Developer API is available to account owners. Generate API tokens from Developer API in the dashboard (/developer-api).

Base URL:

https://live.zappychat.in/api/v1

Authentication

All API requests require a Bearer token in the Authorization header:

Authorization: Bearer YOUR_API_TOKEN

Generate token
Developer API → Create Token → enter a name → Generate.
Copy token immediately
The full token is shown only once. Store it securely.
Use in requests
Include as Bearer token in every API call.

Keep tokens secret Never expose API tokens in client-side code, public repos, or browser JavaScript. Tokens are hashed in the database — lost tokens cannot be recovered, only revoked and recreated.
