Usage

cognitoidentityprovider_list_users(UserPoolId, AttributesToGet, Limit,
  PaginationToken, Filter)

Arguments

UserPoolId

[required] The ID of the user pool on which the search should be performed.
AttributesToGet

A JSON array of user attribute names, for example given_name, that you want Amazon Cognito to include in the response for each user. When you don't provide an AttributesToGet parameter, Amazon Cognito returns all attributes for each user.

Use AttributesToGet with required attributes in your user pool, or in conjunction with Filter. 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 AttributesToGet parameter returns results.
Limit

Maximum number of users to be returned.
PaginationToken

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.
Filter

A filter string of the form ⁠\"AttributeName Filter-Type \"AttributeValue\"⁠. Quotation marks within the filter string must be escaped using the backslash (⁠\⁠) character. For example, ⁠"family_name = \"Reddy\""⁠.

  • AttributeName: The name of the attribute to search for. You can only search for one attribute at a time.

  • Filter-Type: For an exact match, use =, for example, "⁠given_name = \"Jon\"⁠". For a prefix ("starts with") match, use ⁠^=⁠, for example, "⁠given_name ^= \"Jon\"⁠".

  • AttributeValue: The attribute value that must be matched for each user.

If the filter string is empty, list_users returns all users in the user pool.

You can only search for the following standard attributes:

  • username (case-sensitive)

  • email

  • phone_number

  • name

  • given_name

  • family_name

  • preferred_username

  • cognito:user_status (called Status in the Console) (case-insensitive)

  • ⁠status (called Enabled in the Console) (case-sensitive)⁠

  • sub

Custom attributes aren't searchable.

You can also list users with a client-side filter. The server-side filter matches no more than one attribute. For an advanced search, use a client-side filter with the --query parameter of the list-users 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.

For more information about server-side and client-side filtering, see FilteringCLI output in the Command Line Interface User Guide.
