# Apps and books metadata for organizations

Get metadata for apps and books your organization owns.

## Discussion

Use the Apps and Books Metadata for Organizations API to retrieve metadata for apps and books that your organization owns, or to search for and retrieve metadata for apps and books in the public catalog.

This API requires authentication that you’re a member of the Apple Developer Program and a trusted developer. Each request requires a signed developer token as a header. Requests for apps and books your organization owns also require your organization’s `sToken` as a cookie.
