What Are Webhooks? A Complete Guide with SMSGatewayHub Integration
In today’s fast-paced digital world, real-time communication between applications is essential. This is where webhooks come into play. If you're using SMS services like SMSGatewayHub, understanding webhooks can significantly improve your automation and efficiency.
What Are Webhooks?
A webhook is a method that allows one application to send real-time data to another application automatically when a specific event occurs. Unlike traditional APIs that require constant polling (asking repeatedly for updates), webhooks push data instantly.
Simple Definition:
A webhook is an HTTP callback triggered by an event.
Example:
When a user receives an SMS, a webhook can instantly notify your system with delivery status or incoming message data.
How Do Webhooks Work?
Webhooks operate using a simple flow:
- Event Occurs
An event happens in a system (e.g., SMS delivered, message received). - Webhook Triggered
The system sends an HTTP request (usually POST) to a predefined URL. - Data Sent
The request contains event data in JSON or form format. - Your Server Responds
Your application processes the data and returns a response.

Event → Webhook URL → HTTP Request → Your Server → Action
