The users API corresponds to the users resource of the SCIM API.
Full Users API documentation.
Currently only the GET method is partially implemented. The edu-ID SCIM-User API also specifies the Users-Resource-API to create, modify and delete the personal part of an individual's identity, but there are no plans to implement these methods.
To use the Affiliation API an organization must be legally authorized. It is only allowed to access to data of their members, and it must obtain permission from their members to read and further process personal data.
Acccess to the Users-API is only granted to organizations that are legally authorized to do so.
