Using UUID Generator for open banking
Generate identifiers for synthetic API requests, correlation IDs and integration test fixtures.
Sandbox example and expected result
Generate a UUID and use it as a correlation ID in a sandbox request where the provider permits this format.
Limitations and troubleshooting
A fresh ID per retry can defeat idempotency: reuse the same idempotency key for the same logical payment when required by the provider. UUIDs are not credentials.
Where your input is processed
UUIDs are generated in your browser. Use synthetic test data.
