  6. 06API referenceEvery endpoint, field and response.

Connect WhatsApp numbers to your own software, send and receive messages, and get every event pushed to your server — with a simple REST API and webhooks.

What you can build#

  • Messaging inside your CRM. Your users link their WhatsApp number from your app, then chat with customers without leaving it.
  • Reminders and confirmations. Send appointment reminders, order updates and receipts straight from your backend.
  • Automations. React to incoming messages in real time with webhooks.

How it works#

  1. Create an API key in Developer settings.
  2. Connect a number — your users scan a QR code inside your app.
  3. Send messages with POST /v1/messages.
  4. Receive messages on your server through webhooks.

Every request goes to https://api.waconnect.ai/v1 and is authenticated with your API key:

curl https://api.waconnect.ai/v1/me \
  -H "Authorization: Bearer wc_live_your_key"
