How can I test international KYB in sandbox?

Last updated: July 31, 2026

You can validate international searches before going to production.

Different API key

Make sure you are using your sandbox API key, everything else in the sandbox environment is the same as production (URL, payload, etc.). This key is valid for both the US and international sandbox cases.

Available test cases

There are pre-built international sandbox cases you can run to see representative responses. The available international test cases are listed in our published coverage spreadsheet (the same spreadsheet that documents per-country and per-field coverage).

Running a large test

If you want to run a large batch test in production, let your Baselayer contact know so we can make sure it runs smoothly.
