Answer: Map title + downloadable
videoUrl in the Postifys YouTube node/API. Default privacy is private unless you set otherwise. YouTube still processes after submit.What this means in a real publishing workflow
YouTube determines Shorts eligibility from the uploaded video, not from a separate Shorts endpoint in Postifys. The workflow still uses the normal YouTube upload operation with a valid title, channel, privacy setting, and video URL.
Recommended implementation
- Map a non-empty title whose final value is no more than 100 characters.
- Select the correct connected YouTube channel.
- Use a direct media URL that remains available throughout the upload.
- Set privacy, category, tags, audience, and subscriber notification intentionally.
How to verify the fix
Remember to count any hashtags appended by the workflow. A table title of 95 characters becomes invalid if the node adds twelve more characters before sending it to YouTube.
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.
