Problem: The client is using a decoupled website with a Next.js/React frontend and a WordPress backend, attempting to access different translations of a post via the WordPress REST API. They are facing issues when adding the query parameter 'lang=de' to fetch German translations, as no translation information appears in the JSON object. Solution: To fetch all pages in a specific language, such as German, from your WordPress site, you can use the following API endpoint:
/wp-json/wp/v2/pages/?lang=de
If you need to check if the original content has translations, consider using PHP with the following WPML hooks:
Remember, each translation has its own ID, so you might need to query for the ID of the translated post to access specific translations.
