What is Webhook?Webhooks are user-defined callbacks over HTTP meaning it is a way to communicate online applications between each other. A webhook delivers data immediately to other applications, unlike other APIs where you need to poll for the data very frequently to get it real-time. This is extremely beneficial for both the producer and the consumer. For further understanding, let’s consider an example, suppose we have an e-commerce website, and we want to make payment through PayPal, and when a sale is made, we need to send a code/URL to PayPal. This URL is webhook.
How do Webhook work?
- Attach a small code snippet to a web application to listen.
- Trigger event count
- Webhook see the event and catches the specified data.
- Forward the information back to your website application.
- Data is aggregated and consumed
Where can we use?
Push- It is the best reason to use webhooks. As stated above, no more polling, just register a WebHook and receive data at your doorstep within a blink of your eyes.
Pipe- It happens when a Webhook does something additional other than receiving the real-time data. For example- You create a script that creates twitter message and have it triggered by a WebHook whenever you add a new product to your e-commerce website.
Plugin- It lets the entire web to become a programming platform. Here the Webhook, allows others to extend your application same in the case of e-commerce and PayPal.
The other usage may include Chaining, Modifications, Data Synchronisations, etc.
