Sistem pembayaran saya menolak transaksi ketika pelanggan memilih e-wallet Dana—saldo mereka tidak terbaca sama sekali. Saya belum yakin apakah masalah ini muncul di semua transaksi atau hanya kondisi tertentu, jadi saya membutuhkan pemeriksaan menyeluruh. Apa yang saya butuhkan: • Audit cepat pada integrasi Dana di backend (API credential, callback, signature, dan time-stamp). • Replikasi bug hingga jelas terlihat mengapa saldo tidak terdeteksi. • Perbaikan kode atau konfigurasi, lalu uji hingga transaksi sukses. • Dokumentasi singkat berisi langkah perbaikan agar tim internal bisa memelihara ke depan. Stack saat ini: PHP 8 + Laravel, server Nginx, database MySQL. Jika Anda terbiasa dengan webhook Dana dan debugging log payment gateway, pekerjaan ini akan terasa ringan. Harap cantumkan pengalaman serupa, perkiraan waktu pengerjaan, serta daftar akses atau informasi tambahan yang Anda perlukan sebelum mulai.

I can audit and fix the DANA e-wallet payment integration in your PHP 8 + Laravel backend, identify why the customer balance is not being detected, and verify the complete payment flow through a successful transaction. I’ll review the DANA API credentials and configuration, request/response handling, callback and webhook processing, signature validation, timestamp handling, transaction status mapping, and relevant Nginx/Laravel logs. I’ll then reproduce the issue in a controlled environment to determine whether it affects all transactions or only specific payment conditions. Once the root cause is identified, I’ll implement the required code or configuration fix and run end-to-end tests covering payment initiation, callback/webhook processing, balance/status detection, and successful transaction completion. I’ll also provide concise documentation explaining the cause, solution, and maintenance considerations for your internal team. I estimate the initial audit and reproduction will take around 2–4 hours, with the final timeline depending on what the logs and DANA responses reveal. To start, I’ll need access to the relevant Laravel code/configuration, DANA sandbox or production credentials as appropriate, recent payment/webhook logs, and the exact transaction scenario that currently fails. No sensitive credentials need to be shared publicly. Kind regards, Juan
