GSMA Developer Sandbox Registration

The GSMA Developer Sandbox is a free playground designed to help developers explore and test Open Gateway APIs quickly and safely. With real-world auth flows and spec-compliant mock APIs, you can experiment, prototype, and integrate without the complexity of live operator networks.

Key features:

• Realistic hands-on experience with OpenID Connect / OAuth2 authentication and token flows
• CAMARA-compliant certified mock APIs that accept and respond in spec-compliant formats
• Fast start-up – lightweight registration and no heavy onboarding, so you can start coding in minutes
• Safe experimentation without the need for access to live operator networks
• Seamless integration into apps and prototypes, accelerating development and reducing integration risk
