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.
- AnalyticsMetadata
-
The analytics metadata for collecting Amazon Pinpoint metrics for
AdminRespondToAuthChallenge
calls.Type: AnalyticsMetadataType object
Required: No
- ChallengeName
-
The challenge name. For more information, see AdminInitiateAuth.
Type: String
Valid Values:
SMS_MFA | SOFTWARE_TOKEN_MFA | SELECT_MFA_TYPE | MFA_SETUP | PASSWORD_VERIFIER | CUSTOM_CHALLENGE | DEVICE_SRP_AUTH | DEVICE_PASSWORD_VERIFIER | ADMIN_NO_SRP_AUTH | NEW_PASSWORD_REQUIRED
Required: Yes
- ChallengeResponses
-
The challenge responses. These are inputs corresponding to the value of
ChallengeName
, for example:-
SMS_MFA
:SMS_MFA_CODE
,USERNAME
,SECRET_HASH
(if app client is configured with client secret). -
PASSWORD_VERIFIER
:PASSWORD_CLAIM_SIGNATURE
,PASSWORD_CLAIM_SECRET_BLOCK
,TIMESTAMP
,USERNAME
,SECRET_HASH
(if app client is configured with client secret). -
ADMIN_NO_SRP_AUTH
:PASSWORD
,USERNAME
,SECRET_HASH
(if app client is configured with client secret). -
NEW_PASSWORD_REQUIRED
:NEW_PASSWORD
, any other required attributes,USERNAME
,SECRET_HASH
(if app client is configured with client secret).
The value of the
USERNAME
attribute must be the user's actual username, not an alias (such as email address or phone number). To make this easier, theAdminInitiateAuth
response includes the actual username value in theUSERNAMEUSER_ID_FOR_SRP
attribute, even if you specified an alias in your call toAdminInitiateAuth
.Type: String to string map
Required: No
-
- ClientId
-
The app client ID.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern:
[\w+]+
Required: Yes
- ClientMetadata
-
A map of custom key-value pairs that you can provide as input for any custom workflows that this action triggers.
You create custom workflows by assigning AWS Lambda functions to user pool triggers. When you use the AdminRespondToAuthChallenge API action, Amazon Cognito invokes any functions that are assigned to the following triggers: pre sign-up, custom message, post authentication, user migration, pre token generation, define auth challenge, create auth challenge, and verify auth challenge response. When Amazon Cognito invokes any of these functions, it passes a JSON payload, which the function receives as input. This payload contains a
clientMetadata
attribute, which provides the data that you assigned to the ClientMetadata parameter in your AdminRespondToAuthChallenge request. In your function code in AWS Lambda, you can process theclientMetadata
value to enhance your workflow for your specific needs.For more information, see Customizing User Pool Workflows with Lambda Triggers in the Amazon Cognito Developer Guide.
Note Take the following limitations into consideration when you use the ClientMetadata parameter:
-
Amazon Cognito does not store the ClientMetadata value. This data is available only to AWS Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration does not include triggers, the ClientMetadata parameter serves no purpose.
-
Amazon Cognito does not validate the ClientMetadata value.
-
Amazon Cognito does not encrypt the the ClientMetadata value, so don't use it to provide sensitive information.
Type: String to string map
Required: No
-
- ContextData
-
Contextual data such as the user's device fingerprint, IP address, or location used for evaluating the risk of an unexpected event by Amazon Cognito advanced security.
Type: ContextDataType object
Required: No
- Session
-
The session which should be passed both ways in challenge-response calls to the service. If
InitiateAuth
orRespondToAuthChallenge
API call determines that the caller needs to go through another challenge, they return a session with other challenge parameters. This session should be passed as it is to the nextRespondToAuthChallenge
API call.Type: String
Length Constraints: Minimum length of 20. Maximum length of 2048.
Required: No
- UserPoolId
-
The ID of the Amazon Cognito user pool.
Type: String
