03Webhook validate & respond
A Webhook receives a POST, IF checks the required fields, and Respond to Webhook returns 200 or 400. The skeleton for when a form, a payment, or another service calls you. Import-verified only — running it needs a live webhook URL.
Best forreceiving forms, external service callbacks
