Integrating Mobile Money APIs: Orange Money and MTN MoMo for Local Apps
Technical and operational guide to integrating mobile money payments in Cameroon.
Why Mobile Money First
Most consumers pay via mobile money. Apps that ignore Orange Money or MTN MoMo lose conversion at checkout.
Integration Architecture
Initiate payments server-side. Receive signed webhooks. Store transaction references for reconciliation. Never expose API secrets in mobile clients.
User Experience Essentials
Show clear payment status, support timeouts gracefully, and provide SMS/receipt confirmation. Support staff need admin tools to trace stuck payments.
Testing and Go-Live
Use sandbox environments. Run end-to-end tests with small amounts. Monitor failure rates in the first weeks after launch.
Compliance and Reporting
Maintain audit logs for finance teams. Align with partner KYC requirements and internal fraud policies.
