## What / how / who for

**What:** Cart Rocket lets Shopify merchants configure a reusable cart preset (products, quantities, discounts, eligibility, limits, schedule, tracking) and share one link that builds that cart for the customer.

**How:** Merchants install from the Shopify App Store, create a preset in the app admin, copy the rocket link (or download a QR PNG), and place it in ads, email, SMS, creator bios, packaging, or Shopify Flow actions. Cart changes are signed server-side so links cannot be tampered with. Discounts use Shopify’s native discount engine.

**Who for:** Shopify merchants running Meta/Google ads, Klaviyo or other email flows, SMS, influencer/creator drops, QR/print campaigns, VIP or wholesale private offers, and B2B quick reorders.

- **Tag order:** optional per-preset control that adds custom tags to Shopify **orders** placed through that rocket link (e.g. `bfcm-bundle`, `sms-launch`, `meta-retarget`). Existing order tags are preserved (additive). This is order tagging, not Shopify customer tags. Pair with an optional conversion note that appears in order details.

## FAQ (citable answers)

**How does a pre-loaded cart link work?**  
When a customer clicks a Cart Rocket link, it populates their Shopify cart with the merchant-selected products and variants, applies configured discounts, and redirects to cart, checkout, or Shop Pay. Modifications are secured with a server-side signature.

**Does it require theme changes?**  
No. Cart Rocket works independently of the storefront theme and is compatible with Dawn and third-party themes.

**Can discounts stack?**  
Yes. Line-item, cart-wide, shipping, and auto-applied Shopify discount codes can combine in one link via Shopify’s native discount engine.

**Who is it for?**  
Shopify merchants using paid ads, email, SMS, influencer campaigns, QR/print, VIP drops, and reorder flows who want fewer steps between click and purchase.

**Where do I install it?**  
https://apps.shopify.com/smart-checkout-links (search “Cart Rocket” on the Shopify App Store).

## Documentation summary

Official docs: https://cartrocket.dev/docs/ (last updated 2026-08-26).

1. Install Cart Rocket and open the app in Shopify admin.
2. Create cart (or duplicate a preset); name it for analytics (e.g. `bfcm-bundle`).
3. Add products/variants, discounts, eligibility, limits, and active dates.
4. Choose landing mode: cart, checkout, or Shop Pay.
5. Copy the store URL (`https://your-store.myshopify.com/apps/cart/{handle}?utm_...`) or download a QR.
6. Deploy in ads, ESP/SMS, creator bios, or Flow emails.

Discount codes must already exist in Shopify before attaching. Per-customer limits require a logged-in customer. Flow guides are rebuild-in-Flow instructions, not signed `.flow` imports. Tag order writes Shopify order tags (not customer tags); merchants may need to re-approve order-write scopes if prompted.
