Mobile Payoneer Payment Integration

I need to wire my existing mobile app to Payoneer so users can send Payoneer-to-Payoneer transfers directly inside the app. The core objective is simple: once a customer taps “Pay with Payoneer,” the flow should authenticate their Payoneer account, process the payment, and return a clear success or failure response that I can capture in the app’s UI.

The app is already live for iOS and Android; what’s missing is the Payoneer payment layer. You’ll work with my React Native front-end and a Node.js/Express back-end (both on GitHub) and handle everything from generating the API tokens to posting the transaction and confirming the callback. I’ll supply sandbox credentials the moment we start.

Deliverables
• Fully documented Payoneer integration module (front-end hooks + back-end endpoints)
• Environment-specific config so I can switch between sandbox and production with one flag
• A quick README showing setup, test payment steps, and any required Payoneer dashboard settings
• Short video or screenshots proving a successful Payoneer-to-Payoneer transfer on a test account

I’ll consider the job complete once I can clone the repo, drop in my production keys, and run one live transfer without errors. If you have previous Payoneer API experience or live links to apps where you handled the same flow, share them and let’s get started.
