Method Detail

authFlow

public final AuthFlowType authFlow()

The authentication flow for this call to execute. The API action will depend on this value. For example:

• REFRESH_TOKEN_AUTH will take in a valid refresh token and return new tokens.

• USER_SRP_AUTH will take in USERNAME and SRP_A and return the SRP variables to be used for next challenge execution.

• USER_PASSWORD_AUTH will take in USERNAME and PASSWORD and return the next challenge or tokens.

Valid values include:

• USER_SRP_AUTH: Authentication flow for the Secure Remote Password (SRP) protocol.

• REFRESH_TOKEN_AUTH/REFRESH_TOKEN: Authentication flow for refreshing the access token and ID token by supplying a valid refresh token.

• CUSTOM_AUTH: Custom authentication flow.

• USER_PASSWORD_AUTH: Non-SRP authentication flow; USERNAME and PASSWORD are passed directly. If a user migration Lambda trigger is set, this flow will invoke the user migration Lambda if the USERNAME is not found in the user pool.

• ADMIN_USER_PASSWORD_AUTH: Admin-based user password authentication. This replaces the ADMIN_NO_SRP_AUTH authentication flow. In this flow, Cognito receives the password in the request instead of using the SRP process to verify passwords.

ADMIN_NO_SRP_AUTH is not a valid value.

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

Returns:

The authentication flow for this call to execute. The API action will depend on this value. For example:

• REFRESH_TOKEN_AUTH will take in a valid refresh token and return new tokens.

• USER_SRP_AUTH will take in USERNAME and SRP_A and return the SRP variables to be used for next challenge execution.

• USER_PASSWORD_AUTH will take in USERNAME and PASSWORD and return the next challenge or tokens.

Valid values include:

• USER_SRP_AUTH: Authentication flow for the Secure Remote Password (SRP) protocol.

• REFRESH_TOKEN_AUTH/REFRESH_TOKEN: Authentication flow for refreshing the access token and ID token by supplying a valid refresh token.

• CUSTOM_AUTH: Custom authentication flow.

• USER_PASSWORD_AUTH: Non-SRP authentication flow; USERNAME and PASSWORD are passed directly. If a user migration Lambda trigger is set, this flow will invoke the user migration Lambda if the USERNAME is not found in the user pool.

• ADMIN_USER_PASSWORD_AUTH: Admin-based user password authentication. This replaces the ADMIN_NO_SRP_AUTH authentication flow. In this flow, Cognito receives the password in the request instead of using the SRP process to verify passwords.

ADMIN_NO_SRP_AUTH is not a valid value.

AuthFlowType

hasAuthParameters

public final boolean hasAuthParameters()

For responses, this returns true if the service returned a value for the AuthParameters 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.

authParameters

public final Map<String,String> authParameters()

The authentication parameters. These are inputs corresponding to the AuthFlow that you are invoking. The required values depend on the value of AuthFlow:

• For USER_SRP_AUTH: USERNAME (required), SRP_A (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY .

• For REFRESH_TOKEN_AUTH/REFRESH_TOKEN: REFRESH_TOKEN (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY .

• For CUSTOM_AUTH: USERNAME (required), SECRET_HASH (if app client is configured with client secret), DEVICE_KEY. To start the authentication flow with password verification, include ChallengeName: SRP_A and SRP_A: (The SRP_A Value).

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 hasAuthParameters() method.

Returns:

The authentication parameters. These are inputs corresponding to the AuthFlow that you are invoking. The required values depend on the value of AuthFlow:

• For USER_SRP_AUTH: USERNAME (required), SRP_A (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY.

• For REFRESH_TOKEN_AUTH/REFRESH_TOKEN: REFRESH_TOKEN (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY.

• For CUSTOM_AUTH: USERNAME (required), SECRET_HASH (if app client is configured with client secret), DEVICE_KEY. To start the authentication flow with password verification, include ChallengeName: SRP_A and SRP_A: (The SRP_A Value).

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 certain custom workflows that this action triggers.

You create custom workflows by assigning Lambda functions to user pool triggers. When you use the InitiateAuth API action, Amazon Cognito invokes the Lambda functions that are specified for various triggers. The ClientMetadata value is passed as input to the functions for only the following triggers:

• Pre signup

• Pre authentication

• User migration

When Amazon Cognito invokes the functions for these triggers, it passes a JSON payload, which the function receives as input. This payload contains a validationData attribute, which provides the data that you assigned to the ClientMetadata parameter in your InitiateAuth request. In your function code in Lambda, you can process the validationData value to enhance your workflow for your specific needs.

When you use the InitiateAuth API action, Amazon Cognito also invokes the functions for the following triggers, but it does not provide the ClientMetadata value as input:

• Post authentication

• Custom message

• Pre token generation

• Create auth challenge

• Define auth challenge

• Verify auth challenge

For more information, see Customizing User Pool Workflows with Lambda Triggers in the Amazon Cognito Developer Guide.

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 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.

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.
