Hi everyone,I'm a mobile engineer working on payments infrastructure in Latin America. I built an open-source React Native SDK for the MoMo Open API, with Rwanda as the first target market.Repo: https://github.com/francedermaz/openbank-africa-sdkInstall: npm install openbank-africa-sdkNode, PHP and Java wrappers already exist, but I couldn't find a React Native one. MIT licensed, zero runtime dependencies. Collections (Request to Pay, status, balance) and Disbursements (transfer, status, balance, account holder validation), both validated against the real sandbox. Sandbox provisioning is automatic and MTN error reasons are mapped to typed codes.Two things worth knowing that cost me time: Collections and Disbursements are separate subscriptions, each with its own key, API user and token endpoint, and the sandbox only accepts EUR regardless of market. I ran into a few other sandbox quirks along the way, happy to share detail if anyone's stuck.Tell me what's missing from the SDK. Refund a

Hi, I'm integrating the MoMo Collections API (sandbox) into a server-side application. Requests to /collection/v1_0/requesttopay are being rejected with a WAF block page ("Request Rejected... The requested URL was rejected. Please consult with your administrator") when sent from my cloud-hosted server (Render.com), even though the exact same request succeeds when sent from my local machine using identical code and credentials. Could someone confirm whether cloud/datacenter IP ranges are blocked in sandbox, and if so, help whitelist these outbound IP ranges for my app? 74.220.51.0/24 74.220.59.0/24 Account details: API User ID: b3342b64-ffd2-4746-a771-b884953cc72e Thank you!
