API Documentation

  • DandyID's API gives developers the ability to create better social networks by allowing users to more clearly define who they are, helping them to connect with one another on a more personal level, and making it easier for new users to get up and running more quickly. User experience is important, and users on DandyID-enabled sites form tighter bonds with each other and connect in more meaningful ways. DandyID tools can help you turn casual visitors into die-hard fans.
    Getting started with the DandyID API is easy. First apply for an API key, then check out our API documentation below. Also, visit Extend & Share to see some of the apps built on our API. If you have any quesions, or would like to become a trusted partner, please contact us.


    No one wants to fill out the same form over and over. Save your users time and reduce headaches by leveraging the return_profile API call to access a user's globally recognizable profile.


    The return_services and reverse_lookup API calls lets you discover where your users exist on over 250 sites. Use that information to understand them better, connect with them in more meaningful ways and tap into their other online activities.


    (coming soon) A social network is nothing without friends. The return_contacts API call make it easy for your users to connect with their existing contacts on your service.

  • Portable Contacts:

    DandyID also supports Portable Contacts -- an open standard that combines some of the functionality of the API calls listed above.
  • Pro Accounts:
