How this free Pinterest pin scheduler works
Drop a vertical pin image or short video, draft a 100-character title and 500-character description, paste the numeric board ID, add a destination URL, and pick a publish time. The form matches the fields Pinterest API v5 needs on POST /pins.
Pinterest title and description limits
Pinterest enforces a 100-character pin title and 500-character pin description. The counters on this page block save at those limits so you do not waste a scheduled publish on a 400 from the API.
Finding your Pinterest board ID
The Pinterest API needs the numeric board ID (not the username/board-slug URL). Use our free Pinterest board ID finder — paste the board URL, copy the ID, paste it here, and schedule.
- A 2:3 portrait image (1000×1500) is the safest default for the Pinterest home feed.
- Add UTM tags to the destination URL so analytics attribute clicks to Pinterest.
- Schedule a week of pins in one sitting from the Postmixr calendar after signing up.
