Shopify
Use Plandalf beside Shopify for focused offers, campaign pages, paid upgrades, deadline promos, and checkout flows outside the native cart.
Plandalf does not replace Shopify’s store engine. Use it when a campaign, service, add-on, booking, digital product, or paid upgrade should run through a Plandalf offer instead of the native Shopify cart.
Keep the store and the offer separate
Shopify owns the catalog and cart. Plandalf owns the focused offer flow, checkout blocks, deadline context, order bumps, invoices, and follow-up automation.
The path
-
Pick the upsell, booking, service, event, digital product, or campaign checkout that should use Plandalf.
-
Add the organization SDK before the closing
bodytag in the theme or through a managed script area. -
Confirm the Shopify path still works, then complete the Plandalf offer in test mode.
Common patterns
Theme snippet
Shopify offer button
<script src="https://acme.plandalf.com/js/plandalf-sdk.js" async></script><button data-plandalf-present="vip-upgrade">
Add VIP upgrade
</button><button
data-plandalf-present="vip-upgrade"
data-plandalf-apply-promo="launch-week"
data-plandalf-mode="test"
>
Claim launch price
</button>Do not mix carts accidentally
If a buyer should complete the Shopify cart and a Plandalf offer, make the handoff explicit in the page copy and fulfillment workflow. Do not hide a second checkout behind a normal add-to-cart action.
