# Using the AWS SAM CLI with Serverless.tf for local debugging and testing
<a name="using-samcli-serverlesstf"></a>

The AWS Serverless Application Model Command Line Interface (AWS SAM CLI) can be used with Serverless.tf modules for local debugging and testing of your AWS Lambda functions and layers. The following AWS SAM CLI commands are supported:
+ `sam build`
+ `sam local invoke`
+ `sam local start-api`
+ `sam local start-lambda`

**Note**  
Serverless.tf version 4.6.0 and newer supports AWS SAM CLI integration.

To begin using the AWS SAM CLI with your Serverless.tf modules, update to the latest version of Serverless.tf and the AWS SAM CLI.

Starting from **serverless.tf version 6.0.0**, you must set the `create_sam_metadata` parameter as `true`. This generates the metadata resources that the AWS SAM CLI `sam build` command requires.

To learn more about Serverless.tf, see the [terraform-aws-lambda-module](https://registry.terraform.io/modules/terraform-aws-modules/lambda/aws/latest).
