Overview

Welcome to BankU Developers. Find the contracts, request parameters and integration guidance for BankU reseller APIs in one place.

Use the API Reference for endpoint-specific requirements and examples. Use the guides for credentials, network access, activation, responses and safe retries.

API basics

BankU APIs use HTTPS. Each operation documents its HTTP method, path, authentication requirements, request format and response fields. The public documentation website is not your API base URL.

Identity, banking, business and payment workflows have different prerequisites. Product documentation describes a contract; it does not approve access or activate financial services.

Start your integration

1. Choose your API. Read its request fields, prerequisites and response model in API Reference.
2. Prepare access. Use your approved environment, create credentials in ERP and whitelist your server's egress IP.
3. Check the connection. Verify credentials and source IP before requesting product activation.
4. Build and validate. Implement only the documented contract, including error handling, idempotency and reconciliation.

Credentials and security

Keep Client Secret and Encryption Key out of browser code, mobile bundles, source control and logs. Send requests from your authorised server and use HTTPS throughout.

Read each product's limits and retry rules. An HTTP success or timeout does not by itself confirm the business outcome of a financial transaction.
