I want to add Telebirr as an additional payment option on my existing platform. The goal is for customers to complete purchases through Telebirr as smoothly as they do with my current methods. What I need built and working: • Basic transaction processing so users can pay in-app or on-site through their Telebirr wallets. • Automatic retrieval and storage of full transaction history for reporting and reconciliation. • A reliable refund workflow that lets me trigger partial or full refunds directly from my admin panel. You can hook into the official Telebirr API or any proven SDK, but the final code must fit cleanly into my current stack without breaking what is already live. Clear, well-commented source files and a brief setup guide will be the final deliverables.
