Welcome to MistWAPI

MistNex Dynamics provides a fully managed WhatsApp Cloud API. You only verify your token via webhook; clients handle messaging logic themselves.

Authentication

All requests require a client_token in the JSON body:

{
  "client_token": "YOUR_LONG_LIVED_TOKEN"
}

Webhook Verification

Clients verify token by POSTing to our endpoint:

POST https://wapi.mistnex.co.zw/webhook/
Body:
{
  "client_token": "YOUR_LONG_LIVED_TOKEN"
}
Response: 200 OK (token valid)

Send Text Message

{
  "client_token": "YOUR_LONG_LIVED_TOKEN",
  "to_number": "26377XXXXXXX",
  "message": "Hello from WAPI!"
}

Send Template Message

{
  "client_token": "YOUR_LONG_LIVED_TOKEN",
  "to_number": "26377XXXXXXX",
  "template_name": "order_update",
  "parameters": ["John", "Order #1234"]
}

Send Document

{
  "client_token": "YOUR_LONG_LIVED_TOKEN",
  "to_number": "26377XXXXXXX",
  "document_url": "https://example.com/invoice.pdf",
  "filename": "Invoice.pdf"
}
