Because Amazon Cognito invokes this trigger before token generation, you can customize the claims in user pool tokens. With the Basic features of the version one or V1_0 pre token generation trigger event, you can customize the identity (ID) token. In user pools with the Essentials or Plus...
Pre authentication Lambda trigger parameters The request that Amazon Cognito passes to this Lambda function is a combination of the parameters below and the common parameters that Amazon Cognito adds to all requests. JSON { "request": { "userAttributes": { "string": "string", . . . }, "...
One Lambda function cannot trigger another lambda function directly in order to connect these two functions, the first event will have to generate an event for the second function in order to be triggered. For Lambda to know which event will trigger it, can be defined in the configuration sect...

// Create another vector that contains index values. vector<int> indices(3); indices[0] = 0; indices[1] = -1; // This is not a valid subscript. It will trigger an exception. indices[2] = 2; // Use the values from the vector of index values to ...

infrastructure is required, you will need to set it up yourself. For example, the lambda.Kinesis project template shows you how to process incoming Kinesis events, but it does NOT create the Kinesis streams for you, or add the relevant permissions needed for Kinesis to trigger the Lambda ...
However SAM local won't allow you to react to real events or view a chain of events. Suppose a Lambda function that is triggered by a change in a S3 bucket and writes something into a Kinesis stream, which will then trigger another Lambda function. ...
