For Open Bank Project alternatives, define the banking API use case precisely. Account information, payments, and developer sandbox access have different risks.
- Use synthetic accounts to test authentication, consent, scope, and revocation.
- Check transaction identifiers, timestamps, pagination, errors, and idempotency.
- Verify audit logs, rate limits, uptime, and data minimization.
- Compare integration with core banking and third-party developer workflows.
- Seek qualified regulatory and security review before any live customer-data use.
A successful sandbox response does not prove a compliant production integration. Document the jurisdiction and authorized data flow.
