The v1beta version was discontinued on February 28, 2026, causing all
API calls to return HTTP 409 errors. Updated all three endpoint paths
(products list, test connection, reports search) to use v1.
Also updated product attribute access to match v1 schema changes:
- Product.attributes → Product.productAttributes
- attributes.gtin / attributes.gtins → productAttributes.gtins
