Webhooks have gained much popularity in recent years. Due to the advantages they offers. Several well known apps have begun using this functionality.

Many people are still ignorant of its features and intent. You might be interested in learning all the specifics regarding this feature. You will learn everything about webhooks from this article.

What Is A Webhook?

Webhook also known as HTTP push API or web callback is a unique application used to build active communication between applications. Using this tool one application can connect with other applications to share data and files.

When an application tries to connect with another application, webhook automatically creates an event. Because of this, the apps may interact without constantly polling the service to see which one is attempting to connect.

Common Webhook Examples

Consider creating a web application that enables email communication between patients and physicians. In such a system, users should be able to view and respond to messages directly through email in addition to on the application, as well as send messages directly through email.

Additionally, to let users know that a message has been read, you could display read proofs next to each message. This can be done using webhook to make communication easy and efficient.

Various popular applications are using webhook these days. Some common examples include:

Shopify that uses webhook to update and notify its users about new orders they have received through slack.

Plivo is another famous application with millions of users. This application is using webhook for routing text messages or connecting phone calls.

Stripe is also using webhook to help you get an instant notification on your accounting application whenever a person submits a payment.

Hence, webhook is an amazing tool for making it easier for you to track email, message, and data delivery. It can also help you get alerts about clicks, views, and message failures.

Why You Should Use Webhook?

You must use webhooks if you want to include a unique feature in your application that may send out automatic updates on an event that has happened in another application linked to your account.

Moreover, Webhooks are adaptable enough to let developers immediately receive data, enabling them to monitor, interpret, and react to it in any way they consider appropriate.

As compared to API connectivity Webhook is a more useful and appropriate way of building communication between applications. Webhook generates an instant notification when an event occurs so that the users don't need to check their accounts again and again.

Webhook For Email Delivery Alert

You might want to get an alert about the emails delivered from your application. An email webhook can help you in this matter. Using this tool you can get an alert about the email delivery when it reaches your recipient mailbox.

This feature is useful when you are not sure about the messages sent from your application is delivered to your customers' mailbox or not.


Developers can check on the status of their mail stream in a timely manner using the incredibly flexible email webhooks. Along with that, users can also get instant notifications about their messages and emails which was quite difficult before this innovation.

Webhooks have also resolved the significant problem of failed email delivery. Since emails frequently fail for a variety of reasons, such as IP backlisting and bad sender reputation. However, webhook allows the sender to be informed of the mail delivery status.

Using webhooks, you can now send real-time engagement and delivery status updates for emails. Without having to create custom plugins, this API makes it simple to get immediate notifications. Webhook provides details about email delivery events regardless of the language in which it is written. To begin using this feature you can use an Email Tracking API such as MailSlurp.
