My store is running on Shopify Payments and I’m seeing friction at the very last stage: the one-click checkout is not auto-filling customer details as expected. I need someone who can jump in, trace the exact break-point, and make sure the checkout works flawlessly with Gokwick only (Shiprocket isn’t required). Scope • Diagnose why the current Shopify Payments flow fails to retain or pre-populate buyer data during one-click checkout. • Adjust the integration so that every required billing and shipping field is auto-filled when customers hit “Buy Now”. • Test thoroughly on both desktop and mobile to confirm the fix is stable, with no new transaction errors introduced. Please be comfortable working inside the Shopify admin, Theme code, and any relevant Gokwick configuration screens. I’ll provide collaborator access right after we agree on the task and timeline, and I expect a short hand-off guide once the solution is live so I can replicate it in the future if needed.
