Awaiting a signal

Send a sample request or point a webhook provider at the receiver above.

Bearer access

If the server was started with --token, enter it here. The value stays in this browser tab and is never written to disk.
Replay captured request

Requests to private and local addresses are blocked by default. Sensitive and connection-specific headers are never forwarded.
Verify provider signature

Verification uses the exact captured body. The secret is sent only to this local server for this check and is never stored.
