What is a UPI payment gateway?

A UPI payment gateway lets your website or app collect Unified Payments Interface (UPI) payments by creating payment sessions, showing a checkout experience, and notifying your systems via webhooks.

Is Upibridge only for QR codes?

No. Upibridge supports full online checkout via payment links and APIs. QR and scan-based flows are a common use case—not the only one. Learn more on our UPI QR generator page.

Popup vs redirect checkout—what should I use?

Redirect checkout is the default and works everywhere. Popup checkout is optional and can feel smoother when the browser allows it. Regardless of UI mode, webhook verification is the source of truth for success.

How do I trust a successful payment?

Implement your webhook handler and treat webhook-confirmed status as authoritative. Return URLs and front-end events are helpful for UX but not proof of settlement.

How Upibridge checkout works

Redirect checkout is the default: customers complete UPI payment in a full-page flow.
Popup checkout is an optional, free upgrade for UX—open the same payment URL in a focused window when browsers allow it.
Webhook is the only source of truth for payment success. Always confirm funds and order fulfillment server-to-server from your webhook handler.
Treat redirect/return URLs and client-side callbacks as UX hints only—not proof of payment.
