Wapix Developer Documentation

Get up and running with Wapix in three straightforward steps:

All public dispatch endpoints require your secret API key passed in the request body under the field api_key. Management actions performed through the browser use JWT authentication via the standard Authorization: Bearer <token> header.

Dispatches high-priority authentication codes directly to any valid WhatsApp number. The system concatenates your custom text prefix with the numeric OTP code. If delivery cannot be completed due to gateway downtime or invalid recipient, the ₹0.25 fee is automatically refunded to your wallet.
