 - **User data object**
   For user access token, Logto provides additional user data context for you to access. The user data object contains all the user profile data and organization membership data you may need to set up the custom claims. Please check [Users](/user-management/user-data) and [Organizations](/organizations/organization-management#organization-data-structure) for more details.
+- **Organization data object**
+  For [organization access tokens](/authorization/organization-template) (an access token requested for a specific organization), Logto provides the target organization through `context.organization`, so you can attach per-organization claims—for example, mapping the Logto organization ID to an internal ID stored in the organization's custom data. This data object is only present when the token is issued for a specific organization, and contains:
