Remember

Use a test key. Requests go to the sandbox against test partner credentials — no real money can move, and a psg_live_… key is refused here with environment_mismatch.

Pick an endpoint.

The tester runs in your browser and needs JavaScript. The endpoints it calls are documented in the API reference, and every one of them works from curl.

Every endpoint, parameter and body above is read from the gateway’s own OpenAPI document, so this page cannot drift from the API. For the full surface with every schema, see the API reference.

It only talks to the sandbox. The live host is not an option here and cannot be made one from this page — see Going live for why, and Sandbox and testing for what the sandbox does and does not share with production.

If a request fails with a message about the browser not being able to complete it, that is almost always CORS rather than anything wrong with your key or your body. The cURL tab is the test: curl is not a browser, so if the same call works in a terminal, the problem is our configuration. Sandbox and testing explains it.
