## Pinterest as a source

* PostOnce checks Pinterest for new Pins every 10 minutes.
* A deleted or private Pin is skipped with "This Pin was deleted or made private."

## Publishing to Pinterest

Pinterest needs an image or video. Text-only posts are skipped.

| | Limit |
| - | - |
| Title | 100 characters |
| Description | 500 characters |
| Images | 1 to 5 per Pin, 32 MB each, same shape |
| Video | 4 seconds to 5 minutes, up to 2 GB |

**Title:** the source's title, or else the start of the caption.

**Board:** in [Create Post](/help/create-and-schedule-posts) you choose the board. Workflows don't have a board setting. PostOnce uses your saved default board, then a board named "PostOnce", then your first board. If you have no boards, it creates a public board named "PostOnce".

PostOnce creates the cover image for video Pins. If Pinterest rejects images of different shapes, PostOnce posts the first image on its own.

## Pinterest errors

| Error message | What to do |
| - | - |
| "Pinterest authentication failed" | [Reconnect](/help/reconnect-an-account) Pinterest. |
| "Pinterest API rate limit exceeded while creating pin." | Retry later. |
| "Images must have the same width/height ratios" | Use images with the same shape in one Pin. |
| "Pinterest rejected the video during processing. The video was uploaded, but no Pin was created." | Check the video is 4 seconds to 5 minutes, then retry. |
