Razorpay fires both a browser callback and a webhook, and only the webhook is reliable

A successful Razorpay payment produces a browser-side result, either the Checkout handler function or a POST to your callback URL, and separately a server-to-server webhook such as payment.captured. The browser path is lost whenever the customer closes the tab, loses connectivity after a bank redirect, or completes payment inside a UPI app that never returns to the browser. The webhook still arrives.

Systems that mark orders paid only from the callback accumulate paid-but-unfulfilled orders, which for UPI and netbanking is a routine fraction rather than an edge case. Confirm by killing the browser immediately after authorising a test UPI payment. Treat the webhook as the source of truth, make both paths idempotent on the payment ID, and use the callback only to render a result page.
