Scripts for subscriptions
自定义订阅w的购买体验ith Scripts.
When merchants sell subscription products, those product are assigned a selling plan (by the subscription app). When you write scripts, you can use the lineitem object.selling_plan_idto identify when a product is being bought as a subscription.
- Line items for subscriptions have a selling plan ID.
- Line items for one-time purchases don't have a selling plan ID.
A product can be bought both as a subscription and as a one-time purchase. For example, a customer could buy the same bar of soap as a subscription and by itself. Usually there is one line item per product variant in an order. The exception is when an order contains subscriptions. Subscriptions have their own line items in orders. For example, when a customer buys the same soap as a subscription and as a one-time purchase, then there is a line item for each. Similarly subscriptions can have their own shipping lines in an order.

Customers can pay for subscription products with Shopify Payments only. Make sure that you don't have a payment script that hides Shopify Payments. Otherwise, your customer won't be able to pay for their subscription order.
