Class AdminRespondToAuthChallengeRequest

    • Method Detail

      • userPoolId

        public final String userPoolId()

        The ID of the user pool where you want to respond to an authentication challenge.

        Returns:
        The ID of the user pool where you want to respond to an authentication challenge.
      • clientId

        public final String clientId()

        The ID of the app client where you initiated sign-in.

        Returns:
        The ID of the app client where you initiated sign-in.
      • challengeName

        public final ChallengeNameType challengeName()

        The name of the challenge that you are responding to. You can find more information about values for ChallengeName in the response parameters of AdminInitiateAuth.

        If the service returns an enum value that is not available in the current SDK version, challengeName will return ChallengeNameType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from challengeNameAsString().

        Returns:
        The name of the challenge that you are responding to. You can find more information about values for ChallengeName in the response parameters of AdminInitiateAuth.
        See Also:
        ChallengeNameType
      • challengeNameAsString

        public final String challengeNameAsString()

        The name of the challenge that you are responding to. You can find more information about values for ChallengeName in the response parameters of AdminInitiateAuth.

        If the service returns an enum value that is not available in the current SDK version, challengeName will return ChallengeNameType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from challengeNameAsString().

        Returns:
        The name of the challenge that you are responding to. You can find more information about values for ChallengeName in the response parameters of AdminInitiateAuth.

        ChallengeNameType
      • 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. Include a DEVICE_KEY for device authentication.

        SELECT_CHALLENGE

        "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "USERNAME": "[username]", "ANSWER": "[Challenge name]"}

        Available challenges are PASSWORD, PASSWORD_SRP, EMAIL_OTP, SMS_OTP, and WEB_AUTHN.

        Complete authentication in the SELECT_CHALLENGE response for PASSWORD, PASSWORD_SRP, and WEB_AUTHN:

        • "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "ANSWER": "WEB_AUTHN", "USERNAME": "[username]", "CREDENTIAL": "[AuthenticationResponseJSON]"}

          See AuthenticationResponseJSON.

        • "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "ANSWER": "PASSWORD", "USERNAME": "[username]", "PASSWORD": "[password]"}

        • "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "ANSWER": "PASSWORD_SRP", "USERNAME": "[username]", "SRP_A": "[SRP_A]"}

        For SMS_OTP and EMAIL_OTP, respond with the username and answer. Your user pool will send a code for the user to submit in the next challenge response.

        • "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "ANSWER": "SMS_OTP", "USERNAME": "[username]"}

        • "ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "ANSWER": "EMAIL_OTP", "USERNAME": "[username]"}

        SMS_OTP

        "ChallengeName": "SMS_OTP", "ChallengeResponses": {"SMS_OTP_CODE": "[code]", "USERNAME": "[username]"}

        EMAIL_OTP

        "ChallengeName": "EMAIL_OTP", "ChallengeResponses": {"EMAIL_OTP_CODE": "[code]", "USERNAME": "[username]"}

        SMS_MFA

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

        PASSWORD_VERIFIER

        This challenge response is part of the SRP flow. Amazon Cognito requires that your application respond to this challenge within a few seconds. When the response time exceeds this period, your user pool returns a NotAuthorizedException error.

        "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]}

        For more information about SECRET_HASH, see Computing secret hash values. For information about DEVICE_KEY, see Working with user devices in your user pool.

        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. Include a DEVICE_KEY for device authentication.

      • session

        public final String session()

        The session identifier that maintains the state of authentication requests and challenge responses. If an AdminInitiateAuth or AdminRespondToAuthChallenge API request results in a determination that your application must pass another challenge, Amazon Cognito returns a session with other challenge parameters. Send this session identifier, unmodified, to the next AdminRespondToAuthChallenge request.

        Returns:
        The session identifier that maintains the state of authentication requests and challenge responses. If an AdminInitiateAuth or AdminRespondToAuthChallenge API request results in a determination that your application must pass another challenge, Amazon Cognito returns a session with other challenge parameters.

      • analyticsMetadata

        public final AnalyticsMetadataType analyticsMetadata()

        The analytics metadata for collecting Amazon Pinpoint metrics for AdminRespondToAuthChallenge calls.

        Returns:
        The analytics metadata for collecting Amazon Pinpoint metrics for AdminRespondToAuthChallenge calls.
      • contextData

        public final ContextDataType contextData()

        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.

        For more information, see Collecting data for threat protection in applications.

      • hasClientMetadata

        public final boolean hasClientMetadata()
        For responses, this returns true if the service returned a value for the ClientMetadata 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.
      • 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 AdminRespondToAuthChallenge API action, Amazon Cognito invokes any functions that you have assigned to the following triggers:

        • Pre sign-up

        • custom message

        • Post authentication

        • User migration

        • Pre token generation

        • Define auth challenge

        • Create auth challenge

        • 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 that provides the data that you assigned to the ClientMetadata parameter in your AdminRespondToAuthChallenge 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, note 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 send sensitive information in this parameter.

        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.

        Returns:

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
