When accessing the API, you will use the same production URL (https://apiprod.fattlabs.com/) regardless of whether you use a live or sandbox API key. The sandbox is connected to a test gateway, so no real transactions will be processed.

For testing purposes, specific test card numbers are available. Refer to the Test Card Payment Methods.

Once set up with a sandbox, you can test a variety of calls and integrations. See our API and Resource sections.
