In what looks to be a long awaited move to embrace developers and open up their API, Pinterest has created an area with the beginnings of organzed documentation.
and you will find an area with information on the new rich pins, aka “more useful pins”. The developers area also includes links to more information on:
iOS Pin It SDK
Android Pin It SDK
as well as a few tools including the rich pin validator and Widget builder.
The biggest sign of hope for a developer API hook is this manage your apps area to Keep track of the client IDs for your mobile apps.
