Receive and process inbound wire drawdown requests via Column's bank API and decide whether to fulfill or deny each

Verified steps

1. Configure a webhook endpoint to receive wire drawdown request events from Column; when Column receives a wire drawdown request directed at one of your bank accounts, it emits a wire.incoming_drawdown_request.received webhook containing the Wire Drawdown Request object with the requested amount, the Column bank account from which funds would be sent, and the external account to which Column would wire the funds upon approval
2. Validate the incoming drawdown request against your pre-approved counterparty list: verify the requesting institution's routing number and the requested amount fall within your established drawdown agreement parameters; log the request with its Column-assigned ID for audit purposes
3. If the drawdown is approved, submit an approval action via the Column API for the Wire Drawdown Request object; Column will then initiate an outgoing wire transfer per the instructions in the request — note that once approved, the wire is submitted and cannot be recalled through the API
4. If the drawdown is denied or you choose not to act, simply do not approve within the request's validity window; Column treats unanswered requests as ignored and the status transitions accordingly — alternatively submit an explicit denial if the Column API exposes that action
5. Track the Wire Drawdown Request status through the lifecycle: received, approved, denied, completed, or rejected; a rejected status indicates the wire failed after approval (e.g., insufficient funds) and requires out-of-band remediation with the requesting institution
6. Reconcile approved drawdowns in your cash-position ledger: when the wire funds are debited from your Column account, match the outgoing wire transaction to the originating Wire Drawdown Request ID to create a linked record
