I want to add a UPI payment option to my WooCommerce-based WordPress store that accepts money from any UPI platform—Google Pay, PhonePe, Paytm, or whichever app the shopper prefers. As soon as the transaction is approved at the bank’s end, the site must automatically mark the WooCommerce order as “paid” and push the buyer straight to the standard order-confirmation page without manual refreshes or staff intervention. A clean, lightweight solution is ideal—custom plugin, child-theme addition, or a well-supported third-party library modified to fit—so long as it is secure, PCI-compliant, and survives WordPress and WooCommerce updates. I will provide a live UPI VPA for end-to-end testing. Deliver the finished integration fully installed on my staging server, then migrate it to production once I confirm payments flow correctly and orders flip to “processing” automatically. If you have previous experience with UPI intent flows, deep links, or NPCI’s collect requests inside WooCommerce, let me know; that background will make onboarding easier. must work on all platform desktop ,tablet and mobile
