Queue a post to go out at a future time, to one or more connected channels at once (facebook, instagram, threads, tiktok, youtube, linkedin, x, pinterest, bluesky, telegram — TEN channels, and every one of them is live. google_business is accepted by the schema too but is currently HELD BACK: Google allowlists that API per project and ours reads 0 QPM, so it is refused at enqueue rather than failing hours later). A MULTI-SLIDE creative goes in imageUrls[] as a CAROUSEL, in order — never schedule just its first slide. This is how you run a content calendar: schedule now, and Hermoso publishes at the time you set — you do not need to be around. Either name the exact time in `at`, or pass `useQueue:true` to take the brand’s next free POSTING SLOT (its saved posting times, skipping any already occupied) — that is what “just queue it” means and it saves the user picking a minute. Pass a Hermoso render URL as imageUrl/videoUrl (or an upload_file URL for external media). PINTEREST AND YOUTUBE ALSO SHOW A TITLE: pass `title` (max 100 chars) — omit it and Hermoso derives one from the caption’s first sentence rather than truncating the caption mid-word, which is what a Pin headline used to be. A YOUTUBE ITEM’S CAPTION IS ITS TITLE, NOT ITS DESCRIPTION: pass `description` (≤5000 chars) for the box under the video — the links, the CTA and everything YouTube search reads — plus `tags` (up to 30). Omit them and the upload lands with an empty description, which is not recoverable by the time anyone notices. Use `captions` to give each channel its own wording; anything not listed falls back to `message`. PER-CHANNEL SETTINGS, all carried straight through to the real publisher: TIKTOK takes the paid-partnership disclosure (`brandedContent`) and the own-brand one (`yourBrand`) — set them whenever the post is commercial, they are compliance declarations — plus `disableComment` and, on a video, `disableDuet` / `disableStitch` / `coverTimestampMs`. GOOGLE BUSINESS takes `topicType` (STANDARD / EVENT / OFFER / ALERT) with `event` and `offer`, and a real `actionType` button instead of the hard-coded Learn more. X takes a whole `thread`, a `poll`, `replySettings` and `madeWithAi`. INSTAGRAM takes `collaborators` — up to 3 usernames invited to CO-AUTHOR the post, which puts it on their profile too once they accept (the invite is sent when the post fires, and is pending until then). Channels are attempted INDEPENDENTLY, so one failing channel never blocks the others. SOME CHANNELS MUST BE TOLD WHICH ACCOUNT, and Hermoso never guesses one: a Pinterest pin needs `boardId` (list_pinterest_boards) or it is refused outright; a LinkedIn COMPANY PAGE post needs `linkedinOrganizationId` (list_linkedin_pages) and without it the post goes to the connected person’s own profile; a brand with more than one connected Facebook Page needs `pageId` (list_meta_pages) and an account managing more than one Google Business listing needs `locationId` (list_business_locations) — resolve those FIRST and let the user pick, because with several to choose from and no id the post is refused when it fires, hours later. A scheduled post GOES LIVE PUBLICLY by default on every channel — that is what scheduling means, and nothing is ever quietly downgraded to a draft or an unlisted upload. If the user genuinely wants something staged instead, set `visibility` (or `visibilityByChannel` for just one channel): ‘public’ (default, live) · ‘unlisted’ (YouTube only — link-only) · ‘private’ (YouTube private, or TikTok posted SELF_ONLY) · ‘draft’ (TikTok drafts, or an unpublished Facebook Page post for a human to publish). Ask for a weaker visibility only if the user asked for one. If a channel cannot do the visibility requested, the call is REFUSED right now with the reason, rather than posting something weaker later. Most channels publish publicly and nothing else: only YouTube has unlisted/private, only TikTok has private/draft, and only Facebook has draft.
