Learn how webhooks work and explore real-life examples of how they can be used to automate workflows, streamline communication, and improve productivity
Webhooks are a type of Application Programming Interface (API) that allows web apps to send real-time notifications to other applications or services when a specific event occurs.
Traditional APIs require a request to be made by the client application to retrieve data, webhooks on the other hand enable a server-side application to push data to another application in real time when an event occurs.
Compared with the traditional APIs, the benefits of webhooks are as follows:
Better updates:
Webhooks work in real-time to push updates from one application to another, without requiring the client application to constantly query the server for new data. Real-time updates save significant resources on both the client and server sides.
Better performance:
Webhooks push data to the client application as soon as it is available which removes the delay between the server and the client application.
Cutting the delay results in reduced latency which means faster response times and better performance.
Enhanced security:
Webhooks require a callback URL to be set up on the client side. The call-back URL ensures that the server only sends data to the authorized client applications.
Improved flexibility:
Webhooks allow for more flexible integration between applications because they can trigger actions in the client application based on specific events that occur in the server application. This can enable complex workflows and integrations between different applications and services.
Here are some examples of how webhooks work:
Payment notifications:
A payment processing service such as stripe.com could send a webhook notification to a merchant's server when a payment is made on their website. The merchant's server could then trigger a confirmation email to the customer in real-time.
Social media update:
A social media management platform can use webhooks to automatically post updates to social media platforms such as Facebook when a new blog post is published on a website.
Order Fulfilment:
An e-commerce platform can make use of webhooks to notify a warehouse management system when a new order is placed. The warehouse updates its inventory in real-time and sends a notification to the shipping department to fulfil the order.
Chat applications:
A chat application can use webhooks to notify a third-party service such as a project management tool when a user sends a message to a specific channel.
Webhooks are very powerful, they provide an efficient and flexible way to integrate applications and services, with real-time updates and reduced load on servers. Moreover, Webhooks enable us to create complex workflows and integrations between various applications and services.
