Our embedded Shopify app currently relies on the FulfillmentOrderLineItem.line_item property. However, there is a message on the Shopify Partners API health page stating, "UPDATE DEADLINE: October 1, 2023" and directly under it "As of API version 2023-01, FulfillmentOrderLineItem.line_item has been deprecated...".
Considering the 2023-10 API release candidate version still includes the line_item property, it seems unlikely that it will suddenly disappear from the API call on Oct 1. In fact, according to Shopify's API versioning documentation (https://shopify.dev/docs/api/usage/versioning), each stable version is supported for a minimum of 12 months. This means that the earliest removal of the line_item property could be in the 2024-10 API version.
So what will happen after Oct 1 if we don't update our app to use a newer API version? Could our app be delisted?
