Problem: The client is experiencing an issue where product variations such as color and size are not included in the
line_items.name
attribute in the WooCommerce REST API response when the 'WPML Multilingual & Multicurrency for WooCommerce' plugin is active.
Solution: 1. Verify product attribute translation settings through the WooCommerce Multilingual attributes tab. 2. Synchronize product variations using WPML troubleshooting tools and re-save the variable product. 3. Check how variations are displayed in the backend order details in WooCommerce admin and verify the order language. 4. Use the
?lang=nl
parameter in the REST API call. 5. If these steps do not resolve the issue, reproduce the API request on a staging site with the same plugin/theme setup to confirm if there is a compatibility or integration issue between WPML and WooCommerce REST API for variable products. 6. Examine any filters or overrides on the REST API response, particularly those added by WPML or the theme.
