Request Syntax

{ "AnalyticsMetadata": { "AnalyticsEndpointId": "string" }, "ChallengeName": "string", "ChallengeResponses": { "string" : "string" }, "ClientId": "string", "ContextData": { "EncodedData": "string", "HttpHeaders": [ { "headerName": "string", "headerValue": "string" } ], "IpAddress": "string", "ServerName": "string", "ServerPath": "string" }, "Session": "string", "UserPoolId": "string" }

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.

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).
