- Type last changed: v2.119.0 · 11 Jan 2024

## 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';
const preTokenGenerationConfigProperty: cognito.CfnUserPool.PreTokenGenerationConfigProperty = {
  lambdaArn: 'lambdaArn',
  lambdaVersion: 'lambdaVersion',
};
```

## Properties

- `lambdaArn`: string — The Amazon Resource Name (ARN) of the function that you want to assign to your Lambda trigger.

  This parameter and the `PreTokenGeneration` property of `LambdaConfig` have the same value. For new instances of pre token generation triggers, set `LambdaArn` .

- `lambdaVersion`: string — The user pool trigger version of the request that Amazon Cognito sends to your Lambda function.

  Higher-numbered versions add fields that support new features.
