🔌 API Reference

Premium accounts get a REST API for building custom integrations — pull conversations into your own tools, sync visitor data, or send messages programmatically.

Base URL

https://multichat.website/app/mobile-api.php/{endpoint}

Format

JSON requests and responses. Send Content-Type: application/json on POST/PUT bodies.

Auth

Bearer token in the Authorization header — see below.

Authentication

Every endpoint except /login requires an Authorization: Bearer <token> header. You have two ways to get a token:

  • Your account API key — the simplest option for server-to-server integrations. Find it under Settings → API Access in your dashboard and use it directly as the bearer token, no login call needed.
  • A session token — call POST /login with an email/password to get a token that expires after 30 days. This is what the mobile app uses.
POST /app/mobile-api.php/login No auth required

Exchange an email/password for a 30-day session token. Skip this and use your account API key directly if you don't need per-user login.
