Developer Integration Guide

Overview & Authentication

StarterPay provides a lightweight REST API and hosted Payment Links enabling student entrepreneurs in Cameroon to collect Mobile Money payments (MTN MoMo & Orange Money) inside their apps — no RCCM or NIU required.

API Integration

Server-to-Server API

Your backend calls POST /v1/pay with the buyer's details. One single call creates the invoice and triggers the Mobile Money USSD push on the buyer's phone. Best for custom checkout flows.

No-Code

Payment Links

Create a hosted checkout page from your dashboard. Embed the link in your app — StarterPay handles the entire payment UI, provider selection, and USSD prompt. Zero backend code required.

Authentication Header

Every request requires your StarterPay API key sent via the Authorization header:
