We need to display some related posts data (i.e. featured image, title, etc) in our website, but the problem is that the posts are located on another website (which is owned by the same client but in a different 3rd level domain , the source site of related posts is for example houses.italianhomesw.it and the site where the post data shal lbe displayed is apartments.italianhomesw.it).
Is there a way to achieve this result? We need to allow the editor of the site to select some post IDs or post URLS from the source site and insert them in a custom field of the main site.
Thanks for any info about that.
