Install and connect Shopify
Complete this shared setup once, then configure Croissant Pay for your online store, Shopify POS, or both.
1. Install the app
- Install Croissant from the Shopify App Store.
- Authorize the requested permissions. Croissant reads orders, products, customers, gift cards, and returns, and writes discounts and a web pixel.
2. Confirm it connected
In the background, Croissant creates your five discounts and registers the analytics pixel. Nothing on your storefront changes yet — this step is just confirming the backend came up clean.
- Navigate to the Croissant app in your Shopify admin.
- On its Settings page, confirm the connection reads Connected, with all five discounts and the pixel Active.
- Then check Discounts in your Shopify admin directly and confirm the same five discounts are there. The app page is a summary; the admin list is the source of truth.
Warning
If Settings reads Not Connected, this store's domain is not linked to a Croissant merchant account. Nothing will render until it is, and reinstalling does not help — send the exact domain to your Croissant contact.3. Choose your sales channels
Installing the app does not place Croissant Pay in your online store or on a POS smart grid. Continue with the setup guide for each channel your business uses.
| Channel | What you configure | Continue |
|---|---|---|
| Online store | Cart, cart drawer, and checkout surfaces | Online store guide |
| Shopify POS | Smart-grid tile and Croissant tender | POS setup guide |
