Buy Button JS must be upgraded to the latest version

Last year, we announced the deprecation of the Checkout APIs, which Buy Button JS is dependent on. As part of this deprecation, checkout functionality will stop working on older versions of Buy Button JS on August 1, 2025 11:00 AM ET. To maintain functionality for customers to complete purchases, ensure that your app or storefront is on the latest major version of Buy Button JS (v3.0).

For documentation on how to update your Buy Button JS code, refer to the developer docs.

**Critical Deadline: August 1, 2025 11:00 AM ET. **You must update by this date or customers will not be able to complete purchases.
