How it works

Three steps and you're live

Zawa connects to WhatsApp as a linked device, just like WhatsApp Web. The difference is that you drive it over HTTP.

  1. 1

    Create a session

    Get an id and a sessionId, the keys to every other endpoint.

    POST/session
  2. 2

    Scan the QR

    Fetch the QR code and scan it from Linked devices on your phone.

    GET/session
  3. 3

    Send anything

    Text, images, video, documents, locations, or contacts to a number, group, or channel.

    POST/message
