POST
Test a webhook
Saves a call as the sample data of the Webhook received trigger of the flow’s draft. It starts no run and changes nothing in production, so you can build the steps behind the trigger with the real fields of your caller. GET works the same way.

Who may call it

A signed-in editor or admin of the Space may call the address from the browser. Anybody else has to pass the login that the trigger asks for, and gets 401 otherwise. The flow does not have to be published or switched on.

Request

The body may be JSON or text, up to 5 MB. The sample keeps the method, the body and the query. Files are not kept.
