GB Chat API

Welcome to the GB Chat API documentation. This API allows you to send WhatsApp template messages programmatically from your applications.

Overview​

The GB Chat API provides a simple REST interface to:

  • Send Template Messages - Send pre-approved WhatsApp template messages to your customers
  • Receive Webhooks - Get real-time status updates for sent messages (delivered, read, failed)
  • Track Delivery - Monitor message delivery status with your own reference IDs

Quick Start​

1. Get Your API Key​

  1. Log in to your GB Chat Dashboard
