Mark

Search CMS Media

search_cms_media

Read-onlyIdempotent

Searches the images already in one of the connected CMS's media collections, newest first, 24 per page. get_website_cms lists the collections Mark can read (mediaCollections); left out, Mark uses the default, and the reply names the collection it searched. Use a result as a website post's cover with save_post meta.cover = { source: "cms", mediaId, collection }, or attach it to a social post with save_post meta.cmsImages = [{ mediaId, collection }]: Mark keeps a reference, never a copy, and a social post's image is copied to the platform when the post is scheduled. To put one in a website post's body, add alt on its own line with the result's url (the original file): on a rich-text (lexical) mapping Mark publishes it as that media document, uploading nothing. Does not change anything; reads from the customer's CMS. These ids are not Mark asset ids. Related: save_post, get_website_cms, search_assets.
