article_set_data
Idempotent
Set or update a custom data field on an article with any JSON value except null, including nested objects and arrays. Rejects internal_ keys; use article_delete_data to remove keys.
Instructions
Set a single article.data. value (PUT /articles/{id}/data/{key}). To delete a key use article_delete_data. Keys starting with 'internal_' are server-protected and rejected client-side.
