I already run a live Shopify store and now want every buyer to see Snapmint as a seamless EMI payment option during checkout. You’ll take the integration from first credential request through to successful live transactions. What I need you to cover: • Obtain or plug in the required Snapmint API/merchant keys • Install and configure the Snapmint payment gateway inside my Shopify Payments settings (no app currently installed) • Custom-fit the checkout UI so Snapmint’s EMI plans display clearly on product pages, cart, and checkout without slowing the site • End-to-end testing in both sandbox and live modes, including order capture, refunds, partial captures, and settlement reconciliation • Coordinate with Snapmint support if any whitelisting or paperwork is needed • Provide a short hand-off document or screen-share walkthrough so I know where to find logs, enable/disable the gateway, and read basic reports Acceptance criteria: a real order paid through Snapmint on the live storefront, visible in Shopify admin with correct status updates, and no console errors. Familiarity with Shopify Liquid, payment-gateway scripts, and PCI-aware best practices will help this move quickly. Let me know your estimated timeline and any access you’ll need so we can get EMI live for my customers without delay.
