n8n-nodes-chat33

n8n community node for Chat33 — schedule and publish posts
to Instagram, TikTok, YouTube, X and Facebook from your n8n workflows.

Installation

In n8n: Settings → Community Nodes → Install → n8n-nodes-chat33.

Credentials

Create an API key in Chat33 → Settings → API Keys and paste it into the
Chat33 API credential. Scopes needed: accounts:read, posts:read,
posts:write, media:write.

Resources & Operations

Supported platforms: Instagram, Facebook, TikTok, YouTube, X, LinkedIn.

Media size limits

For files over 500 MB, host the file somewhere publicly reachable and use the
URL input type.

Typical workflow

1. Media → Upload the image/video produced earlier in the workflow.
2. Post → Create: pick accounts from the dropdown, set text, paste the
   uploaded URL, optionally schedule.
3. Poll Post → Get or set a callbackUrl to get publish status.

Wait for Delivery

Post → Create normally returns as soon as the post is queued — it goes live a
minute or two later via Chat33's publisher. Turn on Wait for Delivery and
the node polls until the post is actually live, then returns it with the final
externalPostUrl, ready for the next step in your workflow.

• Multi-account posts wait for every account. A failure on one account
  doesn't fail the node: each post returns its own status (PUBLISHED /
  FAILED + error message), so you can branch per platform with an IF node.
• Scheduled posts skip the wait — a post queued for next month can't go
  live inside this run, so it's returned as QUEUED immediately.
• On timeout (default 5 minutes, configurable) still-publishing posts come back
  in their current state rather than as an error — TikTok occasionally takes up
  to an hour. Pair with a callbackUrl if you need a guaranteed notification.

Platform settings

The account dropdown stores channel IDs, so the node cannot tell which
platforms you picked. Tick them under Configure Platform Settings and only
those collections appear.

Every platform Chat33 accepts settings for has a collection here, so nothing
needs hand-written JSON:

• YouTube — tick it on every YouTube post. YouTube/FTC mandates the
  Made for Kids declaration and Chat33 rejects an upload without it. Privacy
  defaults to public, so set Privacy if you want unlisted or private.
  Scheduled posts ignore it: they upload as private and YouTube flips them at
  the scheduled time. Also carries title, description, tags, category and
  subscriber notification.
• TikTok — leave it unticked and the video lands in your TikTok drafts
  rather than publishing. Set Publish Mode to Direct Post to publish, which
  also requires a Privacy Level. Options you don't set are left alone, so
  comments, duets and stitches stay enabled unless you turn them off.
• Instagram — First Comment is posted right after publishing, which is
  where hashtags usually go so they stay out of the caption.
• X — Post as Thread splits the text on a separator and chains each chunk
  as a reply, plus reply permissions.
• LinkedIn — visibility and article card fields; everything you leave blank
  keeps the server-side default.
• Facebook — caption override.

Each collection also has a Caption field that overrides the shared text for
that platform alone, so one node can send a different message to each network.

Anything not covered by the typed collections still goes in Additional
Options → Platform Config (JSON) — full schema at
