Sandbox
A sandbox key runs the same clearing pipeline as production, without production clearance. Send your name, work email, and company, and we email a verification link. After you verify, we issue a gsk_sandbox_… key and an HMAC secret. Issuance follows verification and is not instant. You can read the API Documentation with no account. A live key is a separate step at Production Access.

We email the key one time and cannot show it again, so store it when it arrives.
