Pinterest is essentially a virtual pinboard where users can post and share images, which are referred to as "pins." It can be used to collect recipes, project ideas, clothing items, vacation destinations, and pretty much anything else found online.
This unofficial API was developed at a time when Pinterest lacked their own API, circa June 2012. It has recently run into some difficulties since Pinterest made changes to their backend, but it is still capable of retrieving pins via REST calls.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
