Send a test delivery
POSThttps://api.wapito.com/v1/webhooks/{id}/test
Send a channel token on every request: Authorization: Bearer wpt_YOUR_TOKEN
Posts a synthetic event of the kind you name to the webhook and reports what your endpoint answered: status code, round-trip time and the first part of the response body, plus the exact signature header that was sent so you can replay the verification locally. Nothing is queued and nothing is retried, which makes this safe to call while debugging.
