What is a webhook?
A webhook (also called “reverse API” and “HTTP callback”) is a tool that allows two different systems or web applications to share information.
Webhooks work with event-based triggers. When a specific event occurs in one web app, the webhook will send the other app notifications in real time.
Webhooks have a vast range of use cases. For example, SaaS platforms often use webhooks to share information between related services.
Ecommerce systems use webhooks to push real-time data to payment systems (Shopify and Stripe). Messaging tools also use webhooks to broadcast information from an external source (Slack).
Note that webhooks are automatic. This helps save time and improve the customer experience.
How do webhooks work?
A webhook uses HTTP to send data between two applications or systems. Webhooks enable information to flow one way: from the server application to the client.
First, you need to enter the webhook URL in the client application. This is the webhook endpoint where the server will send new information.
You then need to configure the type of event you want to look for in the server application. For instance, events like user logins or customer purchases can trigger webhooks.
Once you configure the event, the webhook will wait for the event to occur in the server application. The event will automatically trigger what is called an HTTP POST request.
After the event occurs, the webhook will transfer data from the server app to the client app. This data is also called a payload. It often comes in XML or JSON format.
Webhook vs API: What is the difference?
Both webhooks and APIs (application programming interface) allow systems to share information. One of the main differences between webhooks and APIs is that APIs work by polling.
Polling is when the client sends the server an HTTP request to check for new data periodically. You set the time interval to determine how often the server will check for new data.
Webhooks, on the other hand, send the data as soon as the event occurs. They’re often faster than APIs and easier to set up.
