PostbaseHow posting to YouTube works
- Video
- From your library
- The agent finds the video with list_media and attaches it by id. Postbase uploads it to YouTube when it's due.
- Title
- 100
- Characters. Set it with youtube.title, or the post's first line is used.
- Description
- 5,000
- Characters, taken from the post's text.
- Visibility
- 3 options
- Public, Unlisted or Private, per video.
Problems go back to the agent, not out to your followers
- No video
- A YouTube post without a video attached is refused when the agent calls the tool, so it can pick one from your library.
- Made for kids
- YouTube requires every upload to say whether it's made for kids. The agent has to set it, so it should ask you.
- In the past
- A time in the past is refused rather than uploaded straight away.
The tools
The same five tools on every network.
list_channelsRead onlyList channelsPostbaseThe accounts connected to the workspace: id, network, handle and status. The agent calls it first to get channel ids.
No arguments.
create_postWritesCreate or schedule a postPostbaseSaves a draft, or schedules a post or a thread, on one or more channels. The post lands on your Postbase calendar and publishes through each network's official API.
body or thread, channel_ids, scheduled_at (ISO 8601 with an offset) or schedule_in_minutes, and media_ids from list_media. Leave both times out to save a draft.
list_mediaRead onlylist_mediaPostbaseThe images and videos in your Postbase media library, newest first. The agent passes their ids to create_post to attach them.
type (optional): image or video. search (optional): part of a file name.

Frequently asked questions
Can the agent upload a video from my computer?
No. Upload the video to your Postbase media library first. The agent can then find it and schedule it, but it can't send files of its own.
Can it schedule YouTube Shorts?
Yes. A vertical video under YouTube's Shorts length limit is published as a Short.
Does it set the video's visibility?
Yes. The agent can make it Public, Unlisted or Private. If it doesn't say, the video is public.
What about TikTok?
TikTok requires you to choose who sees each post and agree to its terms yourself, so an agent can only save a TikTok draft. You schedule it from the Postbase composer.
