# Lambda

## Overview

**AWS Lambda** is a serverless computing service provided by**Amazon Web Services (AWS)**. Users create**Lambda Functions,** self-contained applications are written in one of the supported languages and runtimes, and upload them to **AWS Lambda,** which executes those Functions in an efficient and flexible manner.

The [Lambda Functions](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-concepts.html#gettingstarted-concepts-function) can perform any kind of computing task, from serving web pages and processing streams of data to calling APIs and integrating with other AWS services. For more information, refer to [AWS Lambda](https://aws.amazon.com/lambda/).

## Lambda Steps

To run the Lambda Steps, it is mandatory to follow the following prerequisite:

- [Install the AWS Module](https://documentation.decisions.com/v9/docs/installing-modules-decisions)
- [An active AWS account](https://signin.aws.amazon.com/signin?redirect_uri=https%3A%2F%2Fconsole.aws.amazon.com%2Fconsole%2Fhome%3FhashArgs%3D%2523%26isauthcode%3Dtrue%26nc2%3Dh_ct%26src%3Dheader-signin%26state%3DhashArgsFromTB_eu-north-1_c1412528899e4833&client_id=arn%3Aaws%3Asignin%3A%3A%3Aconsole%2Fcanvas&forceMobileApp=0&code_challenge=HQku5BPrRUboP5p1wGr4Ai_nBIQNSqsR2eHJNCBfxhQ&code_challenge_method=SHA-256)
- [Configure the Amazon WebServices Settings](https://documentation.decisions.com/v9/docs/setting-up-amazon-webservices-integration)
- [Configure and set up a Lambda Function](https://docs.aws.amazon.com/lambda/latest/dg/lambda-functions.html)

[Amazon Web Services (AWS) Module](https://documentation.decisions.com/v9/docs/setting-up-amazon-webservices-integration) provides pre-built Flow Steps that allow users to invoke a [Function](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-concepts.html#gettingstarted-concepts-function) that processes an [Event](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-concepts.html#gettingstarted-concepts-event). These steps can be found in the Flow Designer at **Toolbox > Integrations > Amazon AWS > LAMBDA**. Currently, there are two steps under Lambda:

| Step Name | Description |
| --- | --- |
| **Run Lambda Function with Data** | Allows you to execute a Lambda Function while providing it with specific payload data in JSON format. This enables you to pass information or parameters which can be used by the Lambda Function during its execution. |
| **Run Lambda Function** | Allows triggering the execution of a specific Lambda Function. |
