Comprehensive Payment Gateway Support Solutions in Patna, Bihar
Integrating an online payment gateway involves far more than pasting a payment button. To prevent "money deducted but order not created" complaints, your backend must verify cryptographic HMAC signatures, handle asynchronous server-to-server webhooks, log transaction IDs in MySQL, and generate instant receipts.
At NS Technologie, our Payment Gateway Support engineers in Patna integrate and troubleshoot all leading Indian and international payment gateways—ensuring 100% transaction reconciliation and RBI compliance.
