API

• We’re happy to announce that you can now retrieve channels to which a product is assigned when you get a product through the Catalog API. You can also filter products by the channel when you Get All Products.

GraphQL

• We added the ability to upgrade a guest cart to a customer cart as part of the login mutation. See the Signing customers in section for details.

B2B

• The following newly-released B2B endpoints for getting and selecting shipping rates on quotes are available to use.

  • Get available shipping rates for quote

  • Get custom shipping methods

  • Select a shipping rate for quote

  • Remove selected shipping rate for quote

Enhancements

• Added required tags to clarify that either a userId or customerId is needed to run the Get Shopping Lists query.

• Updated the description of key in the Widget Template API to prevent confusion.

• Added a 403 response error code to the Create Promotion endpoint.

Bug Fix

• Removed the limit of 40 concurrent requests because only adaptive limits are used for product endpoints.
