Background of the issue:
I am developing a bilingual site (EN + FR) using WordPress and have installed the WPML plugins. I am trying to fetch data from this WordPress site to another site using the REST API. Specifically, I want to get the JSON data for my custom post type called 'news-post'. When I enter the URL hidden link, it returns 10 posts, but I don't see the French data.
Symptoms:
When using the REST API, I am unable to retrieve both English and French data for the 'news-post' custom post type.
Questions:
How can I get both the EN and FR data using the REST API?

Thank you Marcel! From the 2 json urls (hidden link + hidden link), is there any data that connects its secondary language post to the primary language post?
Example:
English post: hidden link
Below is the French translation for the post above: hidden link
From the json file, where does it show that French post is French version of that English post?
The original ID is stored in the "trid" column. You can use the following hooks to retrieve the original ID or its translation:
- wpml_object_id – Retrieves the corresponding object ID in a specific language.
- wpml_element_trid – Gets the translation group (trid) for a given element.
So for your case to get the translated ID in the WP REST API, you can use wpml_object_id. This allows you to retrieve the corresponding translation of a post, page, or custom post type in the desired language. If you need the translated ID in the REST API response, you can modify the API output using a filter like rest_prepare_post. This way, when you request a post via the REST API, it will include the translated version’s ID based on the specified language.
