In our modern digital landscape, seamless functionality is dependent on interconnectivity. Tasks typically involve multiple systems; for instance, e-commerce applications interact with payment systems, which in turn connect to banking systems, ultimately communicating with customer accounts. The ability of independent online systems to communicate and exchange data seamlessly is now central to what makes an online service valuable. Web hooks - our topic today - are one way that applications can send automated messages or information to other applications.
Webhooks have gained popularity in recent years due to the advantages they offer. Many well known apps now use this functionality including GitHub, Slack, Stripe, Twilio, and Zapier etc. In this article, we'll explore webhooks - their functionality, operations, and optimal utilization.
What Is A Webhook?
Webhook also known as HTTP push API, reverse API or web callback is a unique application used to build reactive, event-driven communication between two APIs (application programming interfaces). This characteristically automated tool enables an application to interface with others for the purpose of data and file transmission.
How do Webhooks work?
Such mechanisms facilitate a virtual 'conversation' between systems, where one system (the source) initiates an HTTP request to another system (the destination), effectively exchanging data (the request payload) associated with an event that occurred.
In the process where one application endeavors to establish a connection with another, a webhook automatically generates an event. This capability enables applications to interact without constantly polling the system to determine the initiator of the connection. Webhooks are often utilized by applications to receive small amounts of data from other applications, or to trigger automation workflows in GitOps environments (github webhooks).
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 web-hook to make communication easy and efficient.
Various popular applications are using webhooks 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, web hook 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 can 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.
Webhook vs API
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.
Benefits of Webhooks
- Remove need for polling: Alleviate resource strain by eliminating polling requirements.
- Fast setup: Straightforward, quick setup through the server app interface.
- Automation of Data Transfer: Prompt automated, real-time data transfer upon event occurrence.
- Suitable for specific, light payloads: Support lightweight, server-determined payloads, making them ideal for small data exchanges or notifications.
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 with this. 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.

To Wrap Up
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.
