Building an Open Source SDK for MTN Mobile Money (React Native/TypeScript)

An open-source SDK, openbank-africa-sdk, was released to simplify MTN Mobile Money integration for Node.js and React Native apps.

It automates sandbox setup, OAuth2 authentication, collections, disbursements, and typed error handling through an adapter-based architecture.

The project is MIT licensed and available on GitHub and npm, with plans to extend support to other providers such as Airtel Money.

By packaging MTN MoMo onboarding and transaction flows in TypeScript, it aims to reduce integration effort and implementation errors for African payment apps.
