1. npm install && cp .env.example .env
2. Set Payvib credentials and deploy (Heroku, Railway, etc.)
3. Create a Shopify custom app in Partners; set APP URL to your server
4. Use checkout UI extension or redirect checkout to POST /api/payment/create
5. On payment complete, Payvib redirects to /api/payment/return

Shopify requires a hosted app for native payment apps; this package provides the Payvib API bridge.
