# Deleting a parameter group
<a name="parametergroups.deleting"></a>

You can delete a custom parameter group using the MemoryDB console, the AWS CLI, or the MemoryDB API.

You cannot delete a parameter group if it is associated with any clusters. Nor can you delete any of the default parameter groups.

## Deleting a parameter group (AWS CLI)
<a name="parametergroups.deleting.cli"></a>

To delete a parameter group using the AWS CLI, use the command `delete-parameter-group`. For the parameter group to delete, the parameter group specified by `--parameter-group-name` cannot have any clusters associated with it, nor can it be a default parameter group.

The following sample code deletes the *myRedis6x* parameter group.

**Example**  
For Linux, macOS, or Unix:  

```
aws memorydb delete-parameter-group \
    --parameter-group-name myRedis6x
```
For Windows:  

```
aws memorydb delete-parameter-group ^
    --parameter-group-name myRedis6x
```

## Deleting a parameter group (MemoryDB API)
<a name="parametergroups.deleting.api"></a>

To delete a parameter group using the MemoryDB API, use the `DeleteParameterGroup` action. For the parameter group to delete, the parameter group specified by `ParameterGroupName` cannot have any clusters associated with it, nor can it be a default parameter group.

**Example**  
The following sample code deletes the *myRedis6x* parameter group.  

```
https://memory-db.us-east-1.amazonaws.com/
   ?Action=DeleteParameterGroup
   &ParameterGroupName=myRedis6x
   &SignatureVersion=4
   &SignatureMethod=HmacSHA256
   &Timestamp=20210802T192317Z
   &Version=2021-01-01
