Test-only use
The sandbox is a simulation environment. It does not move money, prove provider settlement or certify an integration for production. Use synthetic data and your own account. Test keys are personal account credentials and must be kept out of public code and customer browsers.
Limits and availability
Each account is limited to 1,000 test intents. Registration and sign-in are subject to attempt limits. Test records and interfaces may evolve as the service develops. The sandbox does not carry a published production availability guarantee or a promise of permanent data retention.
Responsibility for integration code
You are responsible for validating input, safeguarding credentials, verifying live webhooks and preventing duplicate fulfilment in your systems. Do not treat sandbox lifecycle success as a replacement for testing actual receipt formats, network outages and activation recovery.
Moving to production
Live registration and a verified public webhook are separate steps. Provider availability, commercial terms and operational readiness must be confirmed for the intended deployment. Using the sandbox does not grant rights to provider APIs, card acceptance or a regulated financial service.
