<a name="example_lambda_RemovePermission_section"></a>

The following code examples show how to use `RemovePermission`.

------
#### [ CLI ]

**AWS CLI**  
**To remove permissions from an existing Lambda function**  
The following `remove-permission` example removes permission to invoke a function named `my-function`.  

```
aws lambda remove-permission \
    --function-name {{my-function}} \
    --statement-id {{sns}}
```
This command produces no output.  
For more information, see [Using Resource-based Policies for AWS Lambda](https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html) in the *AWS Lambda Developer Guide*.
