Webhooks: How to Use Them and Why You Should

There are many ways to incorporate digital tools into different occupations as technology develops. In order to improve business operations, productivity, and other aspects of work and life, programmers frequently design and incorporate these tools into software that their clients may utilise. To automate processes for your employer or give your clients tools, you might be interested in knowing more about one of these tools, called webhooks. Let’s start with the basics here!

What are Webhooks?

The current, web-based method for servers to receive notifications from other servers is through the use of webhooks.

An HTTP-based callback function called a webhook enables event-driven, lightweight communication between two application programming interfaces (APIs).

In contrast to standard APIs, which require manual data polling, webhooks deliver data to other applications as it happens, so you can access it immediately.

We can use webhooks: 

• To get to know that an event has taken place
• To ensure that data is in-sync across multiple web applications
• To customise/modify the applications and its functionalities based on needs
• To connect two or more applications where an event in one application would trigger an event in another application, so on and so forth.

How to create a webhook supported URL in Salesforce?

1. Create Apex REST API (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_rest.htm)
2. Create a public Site  (https://developer.salesforce.com/docs/atlas.en-us.salesforce_platform_portal_implementation_guide.meta/salesforce_platform_portal_implementation_guide/sites_setup_overview.htm)
3. Enable Apex class Access to the site

To get the complete webhook supported URL, take the Site URL and append it with services/apexrest/[UrL mapping name of your apex rest api]/

Now, locate the Webhook URL input field in the Developer API part of any external service whose settings you want to link with your salesforce system. Use the URL for the webhook you created here, then watch the magic unfold! Tada!

Benefits of using a Webhooks:

Using a webhook provides many benefits for you as a programmer connecting two applications. Some of those benefits include:

Efficiency

With webhooks, you can easily transfer data to other applications without having to set up laborious procedures or risk missing crucial information. Webhooks enable applications to immediately transmit data from triggering events into other apps, as opposed to conventional APIs that poll for data and require users to check for triggering events on a continual basis.

Automation

With the aid of webhooks, you can more easily automate specific data-transfer procedures as well as give users the ability to choose a particular course of action for initiating events in software applications. A webhook is helpful for creating events that you want to happen frequently when the same triggering event occurs many times because it may deliver data instantaneously.

Specificity

Another advantage of using webhooks in programming is that you may connect certain components of an application directly, rather than having to connect several pieces of code to establish a functional data transfer system. By decreasing the amount of complex code in your software, this may make setting up a webhook more quicker and simpler than using other APIs or callbacks. It also helps you keep your code clear and intelligible.

Because you can specify exactly where you want information to come from and go, connecting certain applications may also enable you to develop data transfer systems that are more accurate. Because of this, it might be simpler to develop webhook integrations for applications that let users create custom events and actions.

Less setup

When compared to other techniques, using webhooks to link applications frequently requires less setup time and effort. This is so because webhooks use HTTP, or hypertext transfer protocol, a well-established internet protocol used by the majority of websites to send hypermedia documents like HTML between web browsers and servers. Since HTTP is widely used, adding a webhook to an application without adding new infrastructure to your code is straightforward.

Integration

If you're creating a new application and want to use webhooks to connect with existing applications, this is typically a straightforward process because many applications support webhooks integration. This is beneficial if you want to create an application that includes notifications, messages or events based on the activity of existing applications. You can also create services for users to connect and integrate applications of their choice and create custom triggering events and actions for their jobs or personal productivity.
