= AWS Lambda - Invoke new Lambda = **Summary**: How to use a lambda to invoke a new lambda \\ **Date**: Around 2022 \\ **Refactor**: 20 February 2025: Checked links and formatting. \\ {{tag>aws lambda nodejs}} It would be better to do this using [[awstoolkitforvsc|Step Functions]] but sometimes quick and dirty is good enough. See the code below to invoke a new Lambda function onze your current one is done.


// Lambda Variables
var aws = require('aws-sdk');
var lambda = new aws.Lambda({
  region: 'eu-west-1' //change to your region
});

// Invoke nextlambda if you don't want to use Step Functions

// function invoke Email
function invokeLambdaEmail(requestBody, callback, error){
    var params = {
        FunctionName: 'sendoutEmail',
        InvocationType: 'Event',
        Payload: JSON.stringify(requestBody, null, 2)
      };
      lambda.invoke(params, function(err, data) {
        if (err) console.log(err, err.stack); // an error occurred
        else     console.log(data);           // successful response
      });
}
