# Changing (updating) AWS Lambda function settings by using the AWS Toolkit for JetBrains
<a name="lambda-update"></a>

To use the AWS Toolkit for JetBrains to change (update) the settings for an AWS Lambda function, do one of the following.
+ With the code file open that contains the function handler for [Java](https://docs.aws.amazon.com/lambda/latest/dg/java-programming-model-handler-types.html), [Python](https://docs.aws.amazon.com/lambda/latest/dg/python-programming-model-handler-types.html), [Node.js](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-prog-model-handler.html), or [C\$1](https://docs.aws.amazon.com/lambda/latest/dg/dotnet-programming-model-handler-types.html), on the main menu, choose **Run**, **Edit Configurations**. Complete the [Run/Debug Configurations](run-debug-configurations-dialog.md) dialog box, and then choose **OK**.
+ Open AWS Explorer, if it isn't already open. If you need to switch to a different AWS Region that contains the function, do that now. Expand **Lambda**, choose the name of the function to change the configuration for, and then do one of the following:
  + **Change settings such as the timeout, memory, environment variables, and execution role –** Right-click the name of the function, and then choose **Update Function Configuration**.

    Complete the [Update Configuration](update-configuration-dialog.md) dialog box, and then choose **Update**. 
  + **Change settings such as the input payload** – On the main menu, choose **Run**, **Edit Configurations**. Complete the [Run/Debug Configurations](run-debug-configurations-dialog.md) dialog box, and then choose **OK**.  
![\[Choosing the Edit Configurations command\]](http://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/images/edit-configurations.png)

    If the configuration details are missing, first expand **Templates**, **AWS Lambda**, and then choose **Local** (for the local version of the function) or **Remote** (for the remote version of that same function). Choose **OK**, and then repeat this procedure from the beginning.)
  + **Change settings such as the function handler name or Amazon Simple Storage Service (Amazon S3) source bucket** – Right-click the function name, and then choose **Update Function Code**.  
![\[Choosing the Update Function Code command\]](http://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/images/update-function-code.png)

    Complete the [Update Code](update-code-dialog.md) dialog box, and then choose **Update**.
  + **Change other available property settings that aren't listed in the preceding bullets** – Change those settings in the function's corresponding AWS SAM template file (for example, in a file named `template.yaml` within the project). 

    For a list of available property settings, see [AWS::Serverless::Function](https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction) in the [awslabs/serverless-application-model](https://github.com/awslabs/serverless-application-model/) repository on GitHub.
