ListUsers
Given a user pool ID, returns a list of users and their basic details in a user pool.
Note
Amazon Cognito evaluates AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.
Request Syntax

",
"Limit": number

Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
The request accepts the following data in JSON format.
- 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 anAttributesToGet
parameter, Amazon Cognito returns all attributes for each user.Use
AttributesToGet
with required attributes in your user pool, or in conjunction withFilter
. 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 anAttributesToGet
parameter returns results.Type: Array of strings
Length Constraints: Minimum length of 1. Maximum length of 32.
Pattern:
[\p{L}\p{M}\p{S}\p{N}\p{P}]+
Required: No
- 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,
ListUsers
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.
Note
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 thelist-users
action in the AWS 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 FilteringAWS CLI output in the AWS Command Line Interface User Guide.
For more information, see Searching for Users Using the ListUsers API and Examples of Using the ListUsers API in the Amazon Cognito Developer Guide.
Type: String
Length Constraints: Maximum length of 256.
Required: No
-
- Limit
-
The maximum number of users 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
-
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
- UserPoolId
-
The ID of the user pool where you want to display or search for users.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 55.
Pattern:
[\w-]+_[0-9a-zA-Z]+
Required: Yes

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.
- PaginationToken
-
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]+
- Users
-
An array of user pool users who match your query, and their attributes.
Note
Amazon Cognito creates a profile in your user pool for each local user in your user pool and for each unique user ID from your third-party identity providers (IdPs). When you link users with the AdminLinkProviderForUser API operation, the output of
ListUsers
displays both the IdP user and the local user that you linked. You can identify IdP users in theUsers
object of this API response by the IdP prefix that Amazon Cognito appends toUsername
.Type: Array of UserType objects
