Getting subscription Information At Checkout (Using checkout.liquid)

Cross posting this here as I think I posted it in the wrong section.

In checkout.liquid I need to know if a product is being purchased on a subscription basis. However, line_item.selling_plan_allocation always seems to be nil, so the below outputs nothing.

{%- for line_item in checkout.line_items -%}
  {%- if line_item.selling_plan_allocation != nil -%}
    {{ line_item.product.title }} has selling plan name {{ line_item.selling_plan_allocation.selling_plan.name }}.
  {%- endif -%}
{%- endfor -%}

How should I be accessing the selling plan information for products in the order at checkout? Thanks for any help.

Hi Joelp! I apologize for the late reply.

Selling plan-related customizations are only supported for the product forms, the cart items and the order details. We do not have plans to support selling plan customizations in checkout.liquid.

According to your snippet it seems that you want to exemplify the access to the selling plan allocation for each line item product, but I do wonder whether or not building a post-purchase checkout extension would work for your case.

Best,

Juan
