Permissions are inherited from the parent\nresource.\n\nUser IDs\n--------\n\nA user ID uniquely identifies the operator of a Citizens Broadband Radio Service Device (CBSD).\nSAS uses user IDs to assign a device to a\n[customer](/spectrum-access-system/docs/key-terms).\nEvery SAS customer has to provide at least one user ID during\ncustomer account setup. You can add additional user IDs later.\n\nDevices\n-------\n\nThe SAS Portal API enables multistep registration of\nCBSDs. For devices that need to be installed by a\n[Certified Professional Installer (CPI)](/spectrum-access-system/docs/key-terms), there are two ways\nto initiate the multistep registration process:\n\n- **Option 1.** Initiate the process with a CPI account. The user must be\n authenticated with the [`role_cpi` role](/spectrum-access-system/docs/roles-and-permissions#cpi).\n First, the user is verified by using the\n [`ValidateInstaller()` method](/spectrum-access-system/docs/reference/rest/v1alpha1/installer/validate#spectrum.sas.portal.v1alpha1.DeviceManager.ValidateInstaller),\n and then they use the [`SignDevice()` method](/spectrum-access-system/docs/reference/rest/v1alpha1/deployments.devices/signDevice)\n to send the CPI-validated configuration to SAS.\n\n | **Note:** The user only needs to validate their CPI identity once.\n- **Option 2.** Initiate the process with any account. Any user can use the\n [`CreateSigned()` method](/spectrum-access-system/docs/reference/rest/customers.devices/createSigned)\n to create an inactive device configuration that is ready for the\n CBSD to use. This method uses device parameters that are\n encoded with a CPI's private key.\n\nRegardless of which option you use, this process creates an inactive\nconfiguration for the device in the SAS. Then, the\nCBSD sends a registration request to the SAS. If\nit is successful, the device status changes to **Registered**.\n\n- For CBSDs that do not need CPI validation, use the [`CreateDevice()` method](/spectrum-access-system/docs/reference/rpc/spectrum.sas.portal.v1alpha1#spectrum.sas.portal.v1alpha1.DeviceManager.CreateDevice).\n- For single-step registration with CPI-encoded data, use the [SAS-CBSD API](https://winnf.memberclicks.net/assets/CBRS/WINNF-TS-0016.pdf) defined by WInnForum.\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)."]]
