Shopify E-Commerce With Payment Gateway

The project centres on a brand-new Shopify storefront that must be fully designed, configured, and launched as a conversion-focused e-commerce site. My top priority is a seamless payment experience, so the build needs native integration with Shopify Payments. If technical constraints arise, I can stay flexible and consider PayPal, Stripe, or Square, but the default should remain Shopify’s gateway.

Beyond the standard Shopify setup, the store has to communicate with a third-party API. I will supply endpoint documentation and credentials; the integration should run securely, respect rate limits, and surface the returned data inside the storefront in a way that feels native to the theme.

Deliverables
• Custom Shopify theme (mobile-first, speed-optimised)
• End-to-end configuration of Shopify Payments, fully tested in live mode
• Integration of the specified third-party API, with any required webhooks or middleware
• Clear hand-off notes so I can manage products, orders, and the API connection without developer assistance going forward

Acceptance criteria
– Store loads in under three seconds on desktop and mobile (Google PageSpeed)
– Test orders process successfully via Shopify Payments
– API data displays accurately and updates without manual refresh
– No console errors and liquid files pass Shopify theme check

Code should be clean, commented, and pushed to a private Git repository I will provide. Once the checklist above is met, we can schedule a quick screen-share for final verification before I mark the project complete.
