Publish to a connected Facebook Page, its linked Instagram, OR the brand’s Threads account — text/link/image/VIDEO/CAROUSEL. A MULTI-SLIDE creative is a CAROUSEL, not several posts: pass the slides in order as imageUrls[] and they publish as ONE swipeable post (Instagram album, Threads carousel, Facebook multi-photo post). Never publish slide 1 of a deck on its own — the creative tells the viewer to swipe. target:"facebook" (default) posts to the Page; target:"instagram" publishes a photo or Reel to the linked IG business account (needs an image or video); target:"threads" posts to the connected Threads account (text, image, or video). Works with ANY media — a finished Hermoso ad OR an arbitrary user file: imageUrl/videoUrl accept a public https URL, a data: URI, or a Hermoso /generated path; for a LOCAL file (e.g. on the user’s desktop) call upload_file first and pass the url it returns. INSTAGRAM COLLAB: pass `collaborators` (up to 3 usernames) to invite other accounts to CO-AUTHOR the post — it then shows on their profile too once they accept, which is the reach play behind every creator partnership. This PUBLISHES immediately — confirm the copy + media with the user first. Needs a connected Meta account (Settings ▸ Connectors ▸ Meta) with posting permission; Threads needs its own connection.
