WappBlaster API Documentation

Build custom integrations with our comprehensive API

Contents

Introduction

The WappBlaster API allows you to integrate WhatsApp messaging capabilities into your applications. With our API, you can send messages, manage contacts, track conversations, and automate workflows.

Our RESTful API uses standard HTTP response codes, authentication, and verbs. All responses are returned in JSON format.

Base URL

https://api.wappblaster.com/v1

Authentication

All API requests must include an API key in the Authorization header:

Authorization: Bearer YOUR_API_KEY

Never expose your API key in client-side code. Always make API calls from your server.
