Orders webhooks now include selling_plan_id on line items
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on October 01, 2026.
This Shopify update is categorized as API, Update, Events & webhooks, 2026-10.
What changed
Line items in Orders webhook payloads now include a selling_plan_id field. This field identifies the selling plan applied to a subscription line item, which helps you avoid extra API calls to look up that information. The change applies to API version 2026-10 and later, and you don’t need to take any action to keep your app working. Previously, if your app needed to know which selling plan applied to a subscription line item, it had to make a follow-up Admin API call for every order it received. That value now arrives directly in the webhook payload.
Who is affected
Apps that subscribe to or process Shopify webhooks or event payloads should review this change.
