Background of the issue:
I am working on a site under development and the requirements documentation indicates that a REST API is required. It is unclear which REST API is meant. WooCommerce includes a REST API that requires a key for access. The documentation might be referring to the Legacy REST API, but it does not specify this. The WooCommerce Legacy REST API plugin is not compatible with High-Performance Order Storage, which is used by default in WooCommerce 9.x. I cannot switch to legacy WordPress posts storage, so I cannot install the legacy REST API.
Symptoms:
The documentation is unclear about which REST API is required, and I cannot use the Legacy REST API due to compatibility issues with High-Performance Order Storage.
Questions:
Is the REST API included in WooCommerce 9.x sufficient to meet WPML's requirements?
Does WPML need an API key to access the REST API? If so, how do I configure it?
WooCommerce Multilingual is fully compatible with the WordPress REST API (wp-json). This allows you to create, read, update, and delete translated WooCommerce content seamlessly. You don't need any other, it always refers to the WP REST API.
I discovered that REST API is a build-in feature of WordPress. It can be tested at yourdomain/wp-json and it is active by default. REST API is mentioned as requirement becauser there are plugins and other ways to deactivate it.
