I’m ready to add Instapay to my mobile application so users can initiate and complete transfers without ever leaving the app. The codebase is already stable; what’s missing is a clean, secure Instapay payment flow that covers account linking, transfer execution, confirmation handling, and error reporting. Here’s what I need from you: • Build the Instapay integration directly inside the current mobile project, wiring it to our existing user and transaction models. • Implement the full transfer sequence—initiate, authorise, capture, and display real-time status—using Instapay’s latest SDK / REST endpoints. • Follow best practices for token storage, encryption, and PCI-compliant handling of sensitive data. • Provide unit tests plus a short implementation guide so future releases remain friction-free. When you deliver the final build I’ll run through a test suite covering successful transfers, declined payments, network failures, and UI edge cases. Once everything passes, we’re done.
