![]() ![]() ![]() ![]() At that point, any valid events in the provider’s system should result in a notification being sent to the temporary webhook.site URL you’d copied-and that will allow you to see all of the data received from each new notification that’s generated. Simply pull up that site and copy the temporary URL it generates, then log into your provider’s system and paste the temporary address into their webhook notification field. One, webhook.site, is a particularly indispensable resource. If you’re already up and running with a particular provider and would like to use their data but can’t find an example in their documentation, several online tools may provide some help. Learning that your third-party service is capable of delivering webhook notifications likely led you to this post if you’d like to work with that provider’s actual data, you’ll need to review their API documentation and adapt the code in our example module to accommodate the specific data structure in their notifications.įire up the Postman app on your computer, then follow their guide on importing Postman data to pull in the sample collection (Webhook Entities.postman_collection.json) found in the root directory your downloaded copy of our example module. This piece of the puzzle will be specific to your particular use case. A Data Provider That Dispatches Webhook Notifications Use Cases for WebhooksĪll that’s required in Drupal 8/9 is core-there are no contrib modules required! But, there are a few additional prerequisites to cover before we get started. Webhooks provide a similarly timely heads-up whenever data is modified in an external system, saving you that daily (API) call. While the frequency, urgency, and length of their messages may vary, you always receive their updates on a rolling basis-and only when there’s something that (they feel) you need to know. Webhook notifications are more like that friend who texts throughout the day whenever something happens. Some days will be slow and they won’t have any updates to share, while others are full of news either way, you get a complete rundown of their day in one fell swoop. Think of that process as being akin to calling a friend every evening to find out what’s happened over the past 24 hours. In Drupal, we most commonly rely on a cron task to make periodic requests, tailoring the frequency of those calls to the timeliness of the data that’s being retrieved, the ebb and flow of traffic to the site, or both. If you’ve worked with APIs in the past, you’re probably familiar with the general process: make a request to a third-party service to ask for some data and it responds to let you know what-if anything-is new. Clone that repository to your Custom modules folder and enable it to follow along with our example. You’ll want to begin by downloading the sample Drupal module we’ve assembled from the Bounteous GitHub account. Note: To try out our example code, you can skip over the lengthier explanations and simply follow the instructions in the blue boxes. ![]()
