Respond to webhook
The Respond to webhook block answers the request that ran a webhook event listener with a status code and a body. Use it to return data to the service that called the webhook, or to reject a request, for example with status 401 when its signature is invalid.
The status code must be between 200 and 299 or between 400 and 599. The body can be text or JSON and up to 64 KB. A JSON body has to be valid JSON, so check that placeholders in it don't contain quotes.
A flow can respond once, within 10 seconds of the request, and before any wait that ends the run. Otherwise the request is answered with status 202, and the block only logs a warning.
As long as the flow has this block, every request waits for it, even when the block is in a branch that doesn't run. Respond in every branch, e.g. with status 202, so the sender doesn't wait for the rest of the flow.
