Buy Button SDK - Updates for Buy SDK V3

Topic summary

A developer is seeking clarification on whether the Buy Button SDK will be updated to support Buy SDK V3 before the July 1, 2025 deadline, when Checkout object support ends and transitions to the Cart object.

Key concerns raised:

  • Compatibility with the upcoming V3 release and Cart object migration
  • Status of pending pull requests that contain fixes and updates for the Buy Button SDK repository

Another participant pointed to a relevant GitHub issue (#878) tracking the same question about upgrading the package to JS Buy v3, suggesting this is a broader community concern with ongoing discussion.

Was wondering what the plan is for the Buy Button SDK, with the deprecation of the Buy SDK, and the final release of V3 which should address the Checkout โ†’ Cart object switchover? Will the Buy Button SDK be updated as well, so that we can continue to use it past the July 1, 2025 deadline for the discontinuation of the Checkout object support? Was also wondering if the existing pull requests for the Buy Button SDK could be reviewed and applied, to bring the repo up to date with fixes/updates?
