Class RespondToAuthChallengeRequest

    • Method Detail

      • clientId

        public final String clientId()

        The app client ID.

        Returns:
        The app client ID.
      • session

        public final String session()

        The session that should be passed both ways in challenge-response calls to the service. If InitiateAuth or RespondToAuthChallenge API call determines that the caller must pass another challenge, they return a session with other challenge parameters. This session should be passed as it is to the next RespondToAuthChallenge API call.

        Returns:
        The session that should be passed both ways in challenge-response calls to the service. If InitiateAuth or RespondToAuthChallenge API call determines that the caller must pass another challenge, they return a session with other challenge parameters. This session should be passed as it is to the next RespondToAuthChallenge API call.
      • hasChallengeResponses

        public final boolean hasChallengeResponses()
        For responses, this returns true if the service returned a value for the ChallengeResponses property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • challengeResponses

        public final Map<String,​String> challengeResponses()

        The responses to the challenge that you received in the previous request. Each challenge has its own required response parameters. The following examples are partial JSON request bodies that highlight challenge-response parameters.

        You must provide a SECRET_HASH parameter in all challenge responses to an app client that has a client secret.

        SMS_MFA

        "ChallengeName": "SMS_MFA", "ChallengeResponses": {"SMS_MFA_CODE": "[SMS_code]", "USERNAME": "[username]"}

        PASSWORD_VERIFIER

        "ChallengeName": "PASSWORD_VERIFIER", "ChallengeResponses": {"PASSWORD_CLAIM_SIGNATURE": "[claim_signature]", "PASSWORD_CLAIM_SECRET_BLOCK": "[secret_block]", "TIMESTAMP": [timestamp], "USERNAME": "[username]"}

        Add "DEVICE_KEY" when you sign in with a remembered device.

        CUSTOM_CHALLENGE

        "ChallengeName": "CUSTOM_CHALLENGE", "ChallengeResponses": {"USERNAME": "[username]", "ANSWER": "[challenge_answer]"}

        Add "DEVICE_KEY" when you sign in with a remembered device.

        NEW_PASSWORD_REQUIRED

        "ChallengeName": "NEW_PASSWORD_REQUIRED", "ChallengeResponses": {"NEW_PASSWORD": "[new_password]", "USERNAME": "[username]"}

        To set any required attributes that InitiateAuth returned in an requiredAttributes parameter, add "userAttributes.[attribute_name]": "[attribute_value]". This parameter can also set values for writable attributes that aren't required by your user pool.

        In a NEW_PASSWORD_REQUIRED challenge response, you can't modify a required attribute that already has a value. In RespondToAuthChallenge, set a value for any keys that Amazon Cognito returned in the requiredAttributes parameter, then use the UpdateUserAttributes API operation to modify the value of any additional attributes.

        SOFTWARE_TOKEN_MFA

        "ChallengeName": "SOFTWARE_TOKEN_MFA", "ChallengeResponses": {"USERNAME": "[username]", "SOFTWARE_TOKEN_MFA_CODE": [authenticator_code]}

        DEVICE_SRP_AUTH

        "ChallengeName": "DEVICE_SRP_AUTH", "ChallengeResponses": {"USERNAME": "[username]", "DEVICE_KEY": "[device_key]", "SRP_A": "[srp_a]"}

        DEVICE_PASSWORD_VERIFIER

        "ChallengeName": "DEVICE_PASSWORD_VERIFIER", "ChallengeResponses": {"DEVICE_KEY": "[device_key]", "PASSWORD_CLAIM_SIGNATURE": "[claim_signature]", "PASSWORD_CLAIM_SECRET_BLOCK": "[secret_block]", "TIMESTAMP": [timestamp], "USERNAME": "[username]"}

        MFA_SETUP

        "ChallengeName": "MFA_SETUP", "ChallengeResponses": {"USERNAME": "[username]"}, "SESSION": "[Session ID from VerifySoftwareToken]"

        SELECT_MFA_TYPE

        "ChallengeName": "SELECT_MFA_TYPE", "ChallengeResponses": {"USERNAME": "[username]", "ANSWER": "[SMS_MFA or SOFTWARE_TOKEN_MFA]"}

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasChallengeResponses() method.

        Returns:
        The responses to the challenge that you received in the previous request. Each challenge has its own required response parameters. The following examples are partial JSON request bodies that highlight challenge-response parameters.

        You must provide a SECRET_HASH parameter in all challenge responses to an app client that has a client secret.

        CUSTOM_CHALLENGE

        "ChallengeName": "CUSTOM_CHALLENGE", "ChallengeResponses": {"USERNAME": "[username]", "ANSWER": "[challenge_answer]"}

        Add "DEVICE_KEY" when you sign in with a remembered device.

      • analyticsMetadata

        public final AnalyticsMetadataType analyticsMetadata()

        The Amazon Pinpoint analytics metadata that contributes to your metrics for RespondToAuthChallenge calls.

        Returns:
        The Amazon Pinpoint analytics metadata that contributes to your metrics for RespondToAuthChallenge calls.
      • userContextData

        public final UserContextDataType userContextData()

        Contextual data about your user session, such as the device fingerprint, IP address, or location. Amazon Cognito advanced security evaluates the risk of an authentication event based on the context that your app generates and passes to Amazon Cognito when it makes API requests.

        Returns:
        Contextual data about your user session, such as the device fingerprint, IP address, or location. Amazon Cognito advanced security evaluates the risk of an authentication event based on the context that your app generates and passes to Amazon Cognito when it makes API requests.
      • hasClientMetadata

      • clientMetadata

        public final Map<String,​String> 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 Lambda functions to user pool triggers. When you use the RespondToAuthChallenge API action, Amazon Cognito invokes any functions that are assigned to the following triggers: post authentication, pre token generation, define auth challenge, create auth challenge, and verify auth challenge. 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 RespondToAuthChallenge request. In your function code in Lambda, you can process the clientMetadata 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.

        When you use the ClientMetadata parameter, remember that Amazon Cognito won't do the following:

        • Store the ClientMetadata value. This data is available only to Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration doesn't include triggers, the ClientMetadata parameter serves no purpose.

        • Validate the ClientMetadata value.

        • Encrypt the ClientMetadata value. Don't use Amazon Cognito to provide sensitive information.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasClientMetadata() method.
