Send your first message with the Avox API

The Avox API lets your own systems send WhatsApp messages through your connected number.

Three steps

1. 1In Settings, API Keys, create a key for the number. You confirm it with a code we email you, and the key is shown once, so store it as a server secret.
2. 2Start with a test key: it runs every check but never sends a real message.
3. 3Send a request:

curl -X POST https://api.avox.com/api/messages/send \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"to": "15551234567", "type": "text", "text": {"body": "Hello from Avox"}}'

The body uses WhatsApp's own Cloud API format: text, templates, pictures, documents, locations, buttons and more.
