Project description:
"My storefront is already live on Shopify; the checkout just needs to be wired up to Mollie Payments and then mirrored back into Shopify with the right data. The flow I have in mind is straightforward:

1. Connect Mollie to my existing Shopify checkout so every payment method Mollie offers shows up and processes correctly.
2. Build a lightweight custom script that listens for the Mollie webhook and, on the events “new order”, “order updated”, and “order paid”, calls the Shopify Admin API to recreate or update the order.
3. Push back all the essentials—customer details, product details and full transaction details—so the order timeline inside Shopify matches what actually happened at the gateway.
4. Final-round testing in a staging environment, followed by a quick live-mode confirmation, so I can switch off my old manual reconciling routine immediately.

A clean, commented script (Node.js or PHP are both fine), clear setup instructions, and a short hand-off session will wrap this up for me." (client-provided description)
