Broadcast webhooks

Making sure you receive the information you need when you need it.

Broadcast is a webhook notification system. When an event occurs, it sends a webhook notification to inform you of the situation. You'll find out what happened and the type of issue at hand, enabling you to take action and keep your business running smoothly.

Webhooks provide a definitive confirmation of a status update and are used for a variety of purposes, such as fulfilling orders, sending automated status updates to customers, or even integrating with third-party application services.

Broadcast provides some great features:

  • View a filterable log of all your notifications.
  • Our webhook retry mechanism for failed webhooks.
  • Explanations and reasons why a notification failed.
  • View webhooks for chargebacks and retrievals.

Webhooks example

In the diagram below, a merchant using Checkout.js has configured a charge.captured webhook to trigger a notification to the merchant's server confirming the payment.

It is highly recommended that you use charge.captured as the Webhook trigger since this is the final state of a processed charge.

Setting up Broadcast webhooks

You can take advantage of Broadcast by setting up your webhooks in the Business level administration of The Hub or by using our webhook management API. Easily configure multiple webhook endpoints to perform various processes for each of your channels:

  • Add or remove webhook endpoints
  • Enable or disable a particular endpoint
  • Subscribe or unsubscribe your endpoint event types
  • Add authorization headers to your endpoints

Webhook retries

When a webhook notification fails, the retry mechanism begins. After ten failed webhooks, we send a notification email to inform you that the endpoint is not working. This process repeats seven times, and eventually, if unreachable for a long time, the problematic webhook endpoint is disabled. You can re-enable, view, and configure the webhook at any time in the Business Level Settings of The Hub. If, however, you no longer require this particular webhook endpoint, then no further action is necessary.

Please note:

Amazon’s Simple Queue Service (SQS) features "at-least-once delivery"; this indicates an endpoint could receive a webhook more than once if Broadcast receives duplicate copies of a message. Although this is a rare occurrence, we recommend that endpoints process webhooks in a manner that anticipates duplicates and deals with them appropriately. To do this, save all original webhooks, and when a new webhook is received, disregard it if it already exists.

Requests sent from Broadcast to an endpoint will time out after 30 seconds. Therefore it's vital for the endpoint to return a 2xx HTTP status code before this time expires and the request fails.
