Does Shopify Advanced support selling_plan property in cart liquid?

Topic summary

Issue: After configuring a subscription app for auto-charging, test orders are not being created with the auto-charging subscription plan.

App guidance: The vendor suggested adding the selling_plan property in the cart (cart.liquid) so line items are linked to a subscription plan at checkout.

Key question: Does the Shopify Advanced plan support the Shopify Subscription API’s selling_plan properties (e.g., passing a selling_plan ID on line items), or is this capability limited to Shopify Plus?

Context: “selling_plan” is a line‑item attribute used by the Shopify Subscription API to associate products with recurring purchase plans.

Status: Guidance requested; no answers yet. The thread remains open with uncertainty about whether plan-level (Advanced vs Plus) restrictions affect the use of selling_plan in cart/theme code.

Hi!

We set up a Subscription App for our Shopify store for only auto charging purpose. However, after testing, orders are not being placed with the auto charging plan subscription.

They suggest adding the selling_plan property in the cart. Does Shopify Advanced support the new Shopify Subscription API’s selling_plan properties or only Shopify Plus?

Any guidance would be appreciated.
