Pinterest offers a number of products to allow you to create addons like widgets or buttons for your website or your application, show metadata on a pin, or use tags to track conversions.

The Pinterest API significantly increases the scope of what is possible for you to create as a site or application developer. Standard access to the Pinterest API can be used to:

• View user accounts and user account information
• View, create, or delete Pins
• View, create, update, or delete boards or sections of boards
• View ads, ad groups, campaigns, or ad accounts
• Request analytics information for your Pins, ads, ad groups, campaigns, or accounts

For more information, see: https://developers.pinterest.com/docs/api/v5/

To get started with the Pinterest API and learn about what you need to do to authenticate, read this section of the API documentation. There is also a tutorial that provides a step by step explanation of the authentication process, which uses the OAuth 2.0 standard.
