Frequently Asked Questions

Does CodeMarkers store customer credit card details or UPI PINs on our website?

Never. All sensitive payment credentials are entered directly into the PCI-DSS compliant gateway interface over encrypted HTTPS. Your server only receives transaction status tokens.

What happens if a user's internet drops after paying through their UPI app?

Because we implement server-to-server webhook listeners, the payment gateway notifies your server directly, confirming the order even if the user's browser was closed.

Can we accept international payments from foreign clients?

Yes. Gateways like Stripe and international Razorpay accounts can be configured to accept multi-currency credit and debit cards globally.
