When it fires
Way sendsreview.completed when a review is created for a booking - that is, when a guest submits their rating and feedback for an experience they attended.
Events arrive at your endpoint as a POST request with the body { "event": "review.completed", "payload": { ... } }. When a webhook secret is set, the X-Way-Signature header carries an HMAC of the request body - see Verify signatures.
