Start
Fintwin is a value-added network. The enterprise calls one API contract. Fintwin normalizes it and reaches the bank.
Money movement
Funds move directly between the enterprise account and the customer account at the bank. Fintwin does not open a wallet, hold a balance, or direct those funds.
Three environments on this portal
- Simulator: guests press Try. The portal checks fields and returns a sample. No bank transaction is created.
- Sandbox: after signing in with a company code and authorization key, some APIs call the test environment.
- Production: operating keys are issued separately and are not used on this portal.
Terms
- VAN: a network that connects an enterprise to banks and adds normalization, security, and monitoring.
- VA: a virtual account that identifies who paid. Funds settle to the enterprise main account.
- Webhook: an HTTPS call Fintwin makes to the enterprise system.
- Idempotency: repeating the same TRSC_SEQ_NO or clientMessageId does not create another transaction.
- OTP and app-to-app: how the bank confirms a link or a mandate.
Code 9100 in simulated Try is the portal's own check for a missing field. It is not a bank result code.
