# GetChangeTypeVersion
<a name="API_GetChangeTypeVersion"></a>

Returns information about the specified change type; optionally, you can specify a change type version identifier. By default, the most recent version of the change type is returned.

The information returned includes:
+ Execution approval requirements (`ApprovalCondition`)
+ Whether execution of the change is automated or manual (`AutomationStatus`)
+ Change type deprecation information (`DeprecationMessage` and `DeprecationTime`)
+ An estimate of the time required for execution of the change (`ExpectedExecutionDurationInMinutes`)
+ The parameters that can be specified for the change (`ExecutionInputSchema`)

For more information and examples, see [Understanding Change Types](https://docs.aws.amazon.com/managedservices/latest/userguide/understanding-cts.html) in the *AWS Managed Services User Guide*.

## Request Syntax
<a name="API_GetChangeTypeVersion_RequestSyntax"></a>

```
{
   "ChangeTypeId": "string",
   "Locale": "string",
   "Version": "string"
}
```

## Request Parameters
<a name="API_GetChangeTypeVersion_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [ChangeTypeId](#API_GetChangeTypeVersion_RequestSyntax) **   <a name="amscm-GetChangeTypeVersion-request-ChangeTypeId"></a>
The unique ID of the change type, in the form ct-2ty5seo8rxfsc.  
Type: String  
Required: Yes

 ** [Locale](#API_GetChangeTypeVersion_RequestSyntax) **   <a name="amscm-GetChangeTypeVersion-request-Locale"></a>
The locale (language) to return information in. The default is English. **Note:** For future use; not currently implemented.  
Type: String  
Required: No

 ** [Version](#API_GetChangeTypeVersion_RequestSyntax) **   <a name="amscm-GetChangeTypeVersion-request-Version"></a>
The version identifier of the change type to return.  
If you use the AWS CLI and want to specify a change type version in the request, you must use extra double hyphens (--) to cause the CLI to interpret the `--version` parameter correctly (and not interpret it as a base AWS CLI option). Any base AWS CLI options and parameters (not specific to the AWS Managed Services API), such as `--output` or `--profile`, must appear before the double hyphen. The simplest way to do this is by putting the double hyphens immediately before the `get-change-type-version` command. For example: `aws amscm --output text -- get-change-type-version --version 1.0`   
This special treatment applies only if you specify the parameter on the command line; no special treatment is necessary if you provide parameters in JSON format.
Type: String  
Required: No
