RequestBin is a service that allows users to store and analyze webhooks and other HTTP requests to let them debug these requests. You can use it to create a public endpoint to receive and inspect HTTP requests coming from any source, and then inspect their headers, payloads, and more. The service is free, and doesn’t require you to register if you are fine with your tests being public - if you would prefer them to remain private, however, you will need to register for an account.
