I need a simple, reliable way for small-business users to move funds through DANA. The focus is squarely on the transfer-uang feature—no need for bill payments or full budgeting tools right now. Your task is to wire up DANA’s API (or another proven method you recommend) so that my web or mobile front end can send money quickly and show clear, real-time status updates. Core expectations • Build the transfer module, including authentication, balance check, and confirmation flow. • Provide concise setup instructions and well-commented code so my in-house team can maintain it. • Test with sandbox and one live transaction to prove everything works end-to-end. If you’ve integrated Indonesian e-wallets before—or have solid REST/JSON payments experience—please tell me which projects you handled and how long it took. I’m aiming for a straightforward, production-ready hand-off rather than a long discovery phase.
