Customer Registered Payload
Reference example only — Coi is the caller here, your endpoint is the receiver. Fired once, as a POST with a JSON body, right after a customer registers (self-registration at checkout, or a client created by the merchant in the admin).
Configure the target URL at: Store > Store Settings > "General" tab (כללי) > "Webhook לאחר רישום משתמש".
No authentication header — treat the URL itself as the secret and keep it out of client-side code.
