Once a webhook is created, you can view the list of all the deliveries to the endpoint.
In the Admin Panel's list of webhooks, click on Manage Webhooks, and select any URL to view the list of deliveries for that endpoint. The deliveries are arranged in reverse chronological order according to when they were sent.
The list shows the HTTP status of the response received when the product sends the payload to the endpoint specified in the webhook.
Click View Details to view the exact request and response details of the payload send operation. The details contain request headers, the payload sent, response headers, and a response body.
If you see a delivery with either a status code not present or a delivery with a non-2XX HTTP response code, it means the payload was not delivered correctly for some reason. It may have been a timeout/unavailability at the API endpoint provided.
If you need to send the same payload to the webhook endpoint for any reason, just click Redeliver in the side pane that opens up View Details against a delivery.
