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.
