Many applications send events using webhooks, which are simple HTTP POST request. webhooks.app provides you a dedicated https endpoint, you just need to configure your application so it uses that endpoint, you can then check the payloads received
Example: Harbor registry can send webhooks for many types of events. webhooks.app allows you to quickly visualize the JSON payload sent for each event
webhooks.app is also a very simple backend which allows you to send json payload. You can quickly get the history of your data from the swagger UI or with a good old cURL.
If the data sent to your webhook contains a numeric field, you can visualize its evolution on a simple linear graphics. It's also possible to visualize text in cloud word.
This application is to be used for tests and demos only.
Data are only stored for a couple of days, it's not a production environment in any way (yet...)
Do not send sensitive data to those webhooks
