When you don't provide an <code>AttributesToGet</code> parameter, Amazon Cognito returns all attributes for each user.</p> <p>Use <code>AttributesToGet</code> with required attributes in your user pool, or in conjunction with <code>Filter</code>. Amazon Cognito returns an error if not all users in the results have set a value for the attribute you request. Attributes that you can't filter on, including custom attributes, must have a value set in every user profile before an <code>AttributesToGet</code> parameter returns results.</p><br>

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.</p><br>

Quotation marks within the filter string must be escaped using the backslash (\) character.

The server-side filter matches no more than one attribute. For an advanced search, use a client-side filter with the <code>--query</code> parameter of the <code>list-users</code> action in the CLI. When you use a client-side filter, ListUsers returns a paginated list of zero or more users. You can receive multiple pages in a row with zero results. Repeat the query with each pagination token that is returned until you receive a null pagination token value, and then review the combined result.</p>  <p>For more information about server-side and client-side filtering, see <a href="https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-filter.html">FilteringCLI output</a> in the <a href="https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-filter.html">Command Line Interface User Guide</a>.</p> </note> <p>For more information, see <a href="https://docs.aws.amazon.com/cognito/latest/developerguide/how-to-manage-user-accounts.html#cognito-user-pools-searching-for-users-using-listusers-api">Searching for Users Using the ListUsers API</a> and <a href="https://docs.aws.amazon.com/cognito/latest/developerguide/how-to-manage-user-accounts.html#cognito-user-pools-searching-for-users-listusers-api-examples">Examples of Using the ListUsers API</a> in the <i>Amazon Cognito Developer Guide</i>.</p><br>
