Storefront API changes when Cart ID is missing the key param

API

Effective August 15, 2024

We are modifying how cart queries and mutations behave when the Storefront API Cart ID is missing the key param. This behavior is applied retroactively to all versions of the Storefront API.

An example cart ID: gid://shopify/Cart/c1-7a2abe82733a34e84aa472d57fb5c3c1?key=824bdj25mhg1242bdb385

  • Queries: Querying a cart without including the key param will result in a cart with the buyer's private details removed.

  • Mutations Updating a cart without including the key param will result in an error : The specified cart does not exist.
