spec_type: Webhooks
note: >-
WorldFirst does not publish an AsyncAPI document. It documents an asynchronous
server-to-partner notification (webhook) surface: after a customer completes a
payment or a trade order closes, WorldFirst POSTs a signed notification to the
partner's registered notification URL. Notifications are signed with WorldFirst's
key and MUST be verified by the partner (same RSA256/ECC224 signature model as
requests). The partner acknowledges receipt so WorldFirst stops retrying.
delivery:
style: http-callback
method: POST
content_type: application/json
signature_header: Signature
verification: "Verify with WorldFirst's public key (algorithm=RSA256/ECC224)."
acknowledgement: "Return a success result envelope to stop notification retries."
retries: "WorldFirst retries the notification until acknowledged."
events:
- name: notifyPayment
solution: Pay Solution (Cashier Payment)
trigger: A customer completes (or fails) a Cashier Payment order.
payload: "Payment result carrying the partner paymentRequestId and result envelope."
- name: notifyTradeOrderCloseResult

- name: notifyTransfer

note: "Enterprise payouts are asynchronous; exact callback name is gated behind partner onboarding."
