A free UPI payment gateway tier that still respects enterprise patterns
Prototype fast, keep redirect checkout simple, opt into popup UX when you want it, and always finalize with webhooks. Upibridge offers redirect checkout by default and optional popup checkout (free) for smoother UX. Webhook delivery is the only reliable source of truth for payment success—see webhook documentation.
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.

Frequently asked questions
- Is the gateway really free?
- You can onboard and integrate without licensing narratives described here—final commercial pricing lives in your merchant agreement and dashboard. This page focuses on technical accessibility.
- Do free tiers get webhooks?
- Yes. Webhooks are foundational—not gated—because they protect both you and your customers from ambiguous payment states.
- Popup checkout included?
- Optional popup checkout is available without a separate product SKU. Redirect remains the default for maximum compatibility.
