GuideStar APIs Are Now Even Better

Hundreds of partners rely on our APIs (application programming interfaces) to integrate GuideStar data into their websites and applications. Last year, we proudly released our next generation APIs. We’d completely rebuilt them to provide more powerful searches and more in-depth information. Our customers overwhelmingly embraced these enhancements.

Today, we’re excited to announce additional upgrades to two of our APIs. We’ve added more information, some of it available only through GuideStar, and added new filters so your users can find information in new ways.
