Answer: Every YouTube upload through Postifys needs a connected channel, a reachable video URL, and a non-empty title. Empty titles fail with “invalid or empty video title.”
Required fields
| Field | Required | Notes |
|---|---|---|
| Channel / connection | Yes | Google account with upload scope |
| video URL | Yes | Public or proxyDownload-capable |
| title | Yes | Must be non-empty |
| privacyStatus | Recommended | private / unlisted / public as supported |
- Connect YouTube in Postifys and confirm the channel appears.
- In n8n, map title from your CMS - never leave it blank or whitespace-only.
- Upload, then wait for provider processing before expecting the public watch page.

What this means in a real publishing workflow
A YouTube submission needs a connected channel, a stable video URL, a non-empty title of no more than 100 characters, and valid status metadata. Postifys downloads the source before initiating YouTube’s resumable upload.
Recommended implementation
- Count the final title after workflow-added hashtags.
- Keep the media URL alive for the full download window.
- Choose privacy, category, tags, audience, and notifications intentionally.
- Store the history ID and allow large resumable uploads to finish.
How to verify the fix
If a retry reports 404, replace the expired media URL. If YouTube reports an invalid or empty title, inspect both emptiness and the 100-character maximum.
Operational check: Test with one item, confirm the final destination and Postifys history state, and only then enable the recurring workflow. Keep the returned Postifys ID beside the source row so every result remains traceable.
