Debit mandate
The customer allows the enterprise to debit an account later. This step does not move money.
Flow from the enterprise app
- The enterprise calls registration. The bank checks the account holder, usually with an OTP.
- The enterprise calls confirm. Fintwin returns sourceId, the token used for later debits.
- Cancellation uses the cancel and confirm-cancel pair.
- Resending an OTP uses the same contract, under the recall name.
Webhooks the enterprise builds
Fintwin calls the enterprise to check the contract before registration, then notifies when registration or cancellation has finished at the bank. The enterprise returns errorCode.
