For developers

Connect your application to Prime Pay.

Use the documented API to initiate STK requests, check status, manage payment channels, and receive webhook events.

Integration building blocks

  • API key authentication with test/live environments.
  • STK Push initiation and status lookup.
  • Signed webhook events and retry handling.
  • Sandbox simulation for integration checks.

Sandbox simulation does not initiate a real payment. Production provider support depends on configuration.
