# ListDevices Lists the devices that Amazon Cognito has registered to the currently signed-in user. For more information about device authentication, see [Working with user devices in your user pool](https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-device-tracking.html). Authorize this action with a signed-in user's access token. It must include the scope `aws.cognito.signin.user.admin`. **Note** Amazon Cognito doesn't evaluate AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can't use IAM credentials to authorize requests, and you can't grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see [Using the Amazon Cognito user pools API and user pool endpoints](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pools-API-operations.html). ## Request Syntax ``` { "AccessToken": "string", "Limit": number, "PaginationToken": "string" } ``` ## Request Parameters For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md). The request accepts the following data in JSON format. ** [AccessToken](#API_ListDevices_RequestSyntax) ** A valid access token that Amazon Cognito issued to the currently signed-in user. Must include a scope claim for `aws.cognito.signin.user.admin`. Type: String Pattern: `[A-Za-z0-9-_=.]+` Required: Yes ** [Limit](#API_ListDevices_RequestSyntax) ** The maximum number of devices that you want Amazon Cognito to return in the response. Type: Integer Valid Range: Minimum value of 0. Maximum value of 60. Required: No ** [PaginationToken](#API_ListDevices_RequestSyntax) ** This API operation returns a limited number of results. The pagination token is an identifier that you can present in an additional API request with the same parameters. When you include the pagination token, Amazon Cognito returns the next set of items after the current list. Subsequent requests return a new pagination token. By use of this token, you can paginate through the full list of items. Type: String Length Constraints: Minimum length of 1. Pattern: `[\S]+` Required: No ## Response Syntax ``` { "Devices": [ { "DeviceAttributes": [ { "Name": "string", "Value": "string" } ], "DeviceCreateDate": number, "DeviceKey": "string", "DeviceLastAuthenticatedDate": number, "DeviceLastModifiedDate": number } ], "PaginationToken": "string" } ``` ## Response Elements If the action is successful, the service sends back an HTTP 200 response. The following data is returned in JSON format by the service. ** [Devices](#API_ListDevices_ResponseSyntax) ** An array of devices and their details. Each entry that's returned includes device information, last-accessed and created dates, and the device key. Type: Array of [DeviceType](API_DeviceType.md) objects ** [PaginationToken](#API_ListDevices_ResponseSyntax) ** The identifier that Amazon Cognito returned with the previous request to this operation. When you include a pagination token in your request, Amazon Cognito returns the next set of items in the list. By use of this token, you can paginate through the full list of items. Type: String Length Constraints: Minimum length of 1. Pattern: `[\S]+` ## Errors For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md). ** ForbiddenException ** This exception is thrown when AWS WAF doesn't allow your request based on a web ACL that's associated with your user pool. ** message ** The message returned when AWS WAF doesn't allow your request based on a web ACL that's associated with your user pool.
