API Reference

The Mobile Money (MOMO) Collection API Reference serves as the foundation for all Mobile Money Collection endpoints.

🔐 Authentication

All MOMO Collection API requests require two headers for authentication:

• x-account-id — Your unique partner account identifier provided by TemboPlus.

• x-secret-key — Your API secret key used to authorize and sign each request.

Each request is authenticated by verifying these headers. Requests without valid credentials will return a 401 INVALID_CREDENTIALS error.

For security, never share your secret key publicly or embed it in client-side code.

🧾 Required Request Headers

Each API request must include the following headers:

• Content-Type: application/json Defines the request body format.

• x-account-id: Partner account identifier. Used to identify the organization making the call.

• x-secret-key: Secret key assigned by TemboPlus. Used for authentication.

• x-request-id: A unique UUID generated by you for every request. Helps TemboPlus trace and support your transactions when needed.

Example:
