An organization is a container of other elements: plans, APIs, and clients are defined in the organization. An organization contains and manages all elements used by a company, department, etc. within API Management.
Every user must be associated with at least one organization to be able to manage elements in the application. Scheer PAS API Management implements role-based access control for users. The organization membership of a user defines the actions he is able to perform and the elements he can manage within the organization. Before any other actions can be taken, an organization must exist. All other operations take place within the context of an organization.
