LambdaConfigProperty Struct
A collection of user pool Lambda triggers.
Amazon Cognito invokes triggers at several possible stages of user pool operations. Triggers can modify the outcome of the operations that invoked them.
Example
ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_cognito as cognito } from 'aws-cdk-lib';

lambdaVersion: 'lambdaVersion',
},

Properties
createAuthChallengestringcreate_auth_challengestrcreateAuthChallengeStringCreateAuthChallengestringCreateAuthChallenge*string#The configuration of a create auth challenge Lambda trigger, one of three triggers in the sequence of the [custom authentication challenge triggers](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-challenge.html) .
customEmailSenderIResolvable | CfnUserPool.CustomEmailSenderPropertycustom_email_sendertyping.Union[IResolvable, CustomEmailSenderProperty]customEmailSenderIResolvableCustomEmailSenderIResolvableCustomEmailSenderinterface{}#The configuration of a custom email sender Lambda trigger.
This trigger routes all email notifications from a user pool to a Lambda function that delivers the message using custom logic.
A custom message Lambda trigger.
notes
This trigger is an opportunity to customize all SMS and email messages from your user pool. When a custom message trigger is active, your user pool routes all messages to a Lambda function that returns a runtime-customized message subject and body for your user pool to deliver to a user.
customSmsSenderIResolvable | CfnUserPool.CustomSMSSenderPropertycustom_sms_sendertyping.Union[IResolvable, CustomSMSSenderProperty]customSmsSenderIResolvableCustomSmsSenderIResolvableCustomSmsSenderinterface{}#The configuration of a custom SMS sender Lambda trigger.
This trigger routes all SMS notifications from a user pool to a Lambda function that delivers the message using custom logic.
defineAuthChallengestringdefine_auth_challengestrdefineAuthChallengeStringDefineAuthChallengestringDefineAuthChallenge*string#The configuration of a define auth challenge Lambda trigger, one of three triggers in the sequence of the [custom authentication challenge triggers](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-challenge.html) .
inboundFederationIResolvable | CfnUserPool.InboundFederationPropertyinbound_federationtyping.Union[IResolvable, InboundFederationProperty]inboundFederationIResolvableInboundFederationIResolvableInboundFederationinterface{}#The ARN of an [KMS key](https://docs.aws.amazon.com//kms/latest/developerguide/concepts.html#master_keys) . Amazon Cognito uses the key to encrypt codes and temporary passwords sent to custom sender Lambda triggers.
postAuthenticationstringpost_authenticationstrpostAuthenticationStringPostAuthenticationstringPostAuthentication*string#The configuration of a [post authentication Lambda trigger](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-post-authentication.html) in a user pool. This trigger can take custom actions after a user signs in.
postConfirmationstringpost_confirmationstrpostConfirmationStringPostConfirmationstringPostConfirmation*string#The configuration of a [post confirmation Lambda trigger](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-post-confirmation.html) in a user pool. This trigger can take custom actions after a user confirms their user account and their email address or phone number.

This trigger can evaluate and modify user sign-in events.
The configuration of a [pre sign-up Lambda trigger](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-pre-sign-up.html) in a user pool. This trigger evaluates new users and can bypass confirmation, [link a federated user profile](https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-identity-federation-consolidate-users.html) , or block sign-up requests.

notes
Set this parameter for legacy purposes. If you also set an ARN in PreTokenGenerationConfig , its value must be identical to PreTokenGeneration . For new instances of pre token generation triggers, set the LambdaArn of PreTokenGenerationConfig .
preTokenGenerationConfigIResolvable | CfnUserPool.PreTokenGenerationConfigPropertypre_token_generation_configtyping.Union[IResolvable, PreTokenGenerationConfigProperty]preTokenGenerationConfigIResolvablePreTokenGenerationConfigIResolvablePreTokenGenerationConfiginterface{}#The detailed configuration of a [pre token generation Lambda trigger](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-pre-token-generation.html) in a user pool. If you also set an ARN in `PreTokenGeneration` , its value must be identical to `PreTokenGenerationConfig` .
The configuration of a [migrate user Lambda trigger](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-migrate-user.html) in a user pool. This trigger can create user profiles when users sign in or attempt to reset their password with credentials that don't exist yet.
