These roles are\nassigned to the user's Google Account.\n\nUser roles\n----------\n\nThe roles assigned to a user are [`role_admin`](/spectrum-access-system/docs/roles-and-permissions#admin)\nand [`role_cpi`](/spectrum-access-system/docs/guides/roles-and-permissions#cpi).\nEach user can be assigned to one or more roles.\n\n### role_admin\n\nThe first user of a SAS customer's organization is the\n*administrator*. The administrator is automatically added during the sign-up\nprocess. The administrators can then add other users and assign them roles,\nincluding the administrator role.\n\nThe administrator role has full administrative permissions for all of the child\n[resources](/spectrum-access-system/docs/manage-resources) under the parent\nresource to which it has been granted access. The administrator sets up the\norganization's structure within the SAS Portal and manages user\naccess.\n\n### role_cpi\n\nThe [CPI](/spectrum-access-system/docs/key-terms) role is for users who are\n*Certified Professional Installers* . To be assigned this role, users need to\nhave an active CPI certification. To validate if a user has this certification,\nuse the [`ValidateInstaller()` method](/spectrum-access-system/docs/reference/rest/v1alpha1/installer/validate#spectrum.sas.portal.v1alpha1.DeviceManager.ValidateInstaller).\n\nOnly users with a validated `role_cpi` role can use the\n[`SignDevice()` method](/spectrum-access-system/docs/reference/rest/v1alpha1/deployments.devices/signDevice)\nto submit the installation parameters of CBSDs that\nrequire CPI installation.\n\nMethods\n-------\n\nThe following table shows which roles can use each type of method.\n\nWhat's next\n-----------\n\n- To get an overview of the SAS Portal API, see [Google SAS Portal API overview](/spectrum-access-system/docs/overview-api).\n- For information about each API, see [Customers API](/spectrum-access-system/docs/customers-api) and [Device Manager API](/spectrum-access-system/docs/device-manager-api).\n- For examples of how to use the API, see [API code samples](/spectrum-access-system/docs/samples).\n- For reference documentation, see [APIs and reference](/spectrum-access-system/docs/apis)."]]
