Simulate the bank confirming an account closure (sandbox only)

​

After a donor cancels, Roster asks the bank to close the donor's sub-account; the closure itself is a fact the bank confirms later. This simulator plays the bank: it finds the pending closure request for the enrollment and delivers the confirmation through the same production webhook path. Requires a prior cancellation. Once the bank has confirmed the closure, a new request is refused with 400 and nothing is sent.

Headers

  • Idempotency-Key
    Type: string
    min length:  
    1
    max length:  
    255
    required

    Required on every POST, before any effect: 1–255 visible ASCII characters, no spaces. The key belongs to the first body sent with it on this operation for 30 days from the moment that request arrives, including while that request is running and after a 5xx or a timeout. On an operation that creates a resource (POST /v1/churches, POST /v1/churches/import, POST /v1/church_consents, POST /v1/donor_sessions, POST /v1/manage_sessions, POST /v1/refunds and POST /v1/webhook_endpoints), a key whose request succeeded keeps its body for as long as the resource it created exists. A creation replayed with the same key and body returns the original resource with 200 and changes nothing; a 4xx releases the key.
