Retrieve a webhook
Authentication
Path parameters
UUID of the outbound webhook. It must belong to the authenticated workspace; an id from another workspace answers 404, exactly like an unknown one. Returned as id by GET /api/webhooks.
Response
An outbound webhook exactly as the API serializes it: the stored row with snake_case keys.
secret is masked as "[configured]" on list, retrieve and update. The plaintext signing secret
is returned only once, in the POST /api/webhooks response, and a new one by rotate-secret.
Custom headers are returned as stored, in plaintext.
