What Pinterest allows a scheduler to do

Read on 2026-10-12. Where Pinterest’s pages are silent, so is this one.

What Pinterest’s API lets a scheduler publish

A Pin is created on a board, or on a section of a board, that the account owns, with a title, a description, a destination link and alt text. Pinterest says it has simplified organic formats to image Pins and video Pins; a video Pin is registered, uploaded as an MP4, MOV or M4V file and published with a cover image.

Pinterest reserves the create call for new content made by the user. Saving other people’s Pins to your boards is meant to go through its Save button instead. An account holds up to 2,000 boards and 200,000 Pins.

A person chooses each Pin

Pinterest’s developer guidelines list Pin schedulers among the tools it expects, with one condition: an app may not let people start actions automatically without considering each one. Its own example is scheduling, where “the end user must choose each Pin to be published”. A tool that turns a feed into Pins therefore has to put each one in front of you first.

Trial and Standard access

Every app starts with Trial access. What it creates are sandbox Pins and boards that only their creator sees, and the whole app is limited to 1,000 requests a day. Standard access, granted after Pinterest reviews a recording of the app in use, is counted by the minute for each user.

FAQ

Frequently asked questions

Can I choose which board a Pin goes to?

At launch you will pick a board for each Pin when you schedule it. Pinterest’s API creates a Pin on one board, or one section of a board, that your account owns.

How will my AI agent post to Pinterest through Postnavo?

Once Postnavo launches, you connect your agent and ask it to prepare Pins, for example one for each new article on your blog, with a title, a description and the link. Pinterest asks that a person chooses each Pin that is published, so the Pins wait for your confirmation.

Can Pins be created automatically from my blog’s RSS feed?

Pinterest’s developer guidelines say that when an app schedules Pins, the person must choose each Pin to be published. At launch, Postnavo will prepare Pins from new feed items and wait for you to confirm them.

How long can a Pin description be?

Up to 800 characters, with a title of up to 100, in both Pinterest’s API reference and its spec guide. Pinterest says the first 40 characters of a title may show in people’s feeds.
