Overview
Install the topropay app from the Shopify App Store (or via a custom-app install URL). The app injects a checkout extension that adds topropay as a payment option at the standard Shopify checkout page — no theme edits, no JavaScript pasted into Liquid.
What you get
- Checkout extension — no Theme.liquid changes, survives every theme update
- Shopify Plus compatible (Functions + Checkout UI extensions)
- Orders, refunds, and chargebacks sync into the Shopify admin
- Per-country connector priority — meet local-payment-method requirements
