# DeletePermissionVersion
<a name="API_DeletePermissionVersion"></a>

Deletes one version of a customer managed permission. The version you specify must not be attached to any resource share and must not be the default version for the permission.

If a customer managed permission has the maximum of 5 versions, then you must delete at least one version before you can create another.

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

```
DELETE /deletepermissionversion?clientToken=clientToken&permissionArn=permissionArn&permissionVersion=permissionVersion HTTP/1.1
```

## URI Request Parameters
<a name="API_DeletePermissionVersion_RequestParameters"></a>

The request uses the following URI parameters.

 ** [clientToken](#API_DeletePermissionVersion_RequestSyntax) **   <a name="ram-DeletePermissionVersion-request-uri-clientToken"></a>
Specifies a unique, case-sensitive identifier that you provide to ensure the idempotency of the request. This lets you safely retry the request without accidentally performing the same operation a second time. Passing the same value to a later call to an operation requires that you also pass the same value for all other parameters. We recommend that you use a [UUID type of value.](https://wikipedia.org/wiki/Universally_unique_identifier).  
If you don't provide this value, then AWS generates a random one for you.  
If you retry the operation with the same `ClientToken`, but with different parameters, the retry fails with an `IdempotentParameterMismatch` error.

 ** [permissionArn](#API_DeletePermissionVersion_RequestSyntax) **   <a name="ram-DeletePermissionVersion-request-uri-permissionArn"></a>
Specifies the [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) of the permission with the version you want to delete.  
Required: Yes

 ** [permissionVersion](#API_DeletePermissionVersion_RequestSyntax) **   <a name="ram-DeletePermissionVersion-request-uri-permissionVersion"></a>
Specifies the version number to delete.  
You can't delete the default version for a customer managed permission.  
You can't delete a version if it's the only version of the permission. You must either first create another version, or delete the permission completely.  
You can't delete a version if it is attached to any resource shares. If the version is the default, you must first use [SetDefaultPermissionVersion](API_SetDefaultPermissionVersion.md) to set a different version as the default for the customer managed permission, and then use [AssociateResourceSharePermission](API_AssociateResourceSharePermission.md) to update your resource shares to use the new default version.  
Required: Yes

## Request Body
<a name="API_DeletePermissionVersion_RequestBody"></a>

The request does not have a request body.

## Response Syntax
<a name="API_DeletePermissionVersion_ResponseSyntax"></a>

## Response Elements
<a name="API_DeletePermissionVersion_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [clientToken](#API_DeletePermissionVersion_ResponseSyntax) **   <a name="ram-DeletePermissionVersion-response-clientToken"></a>
The idempotency identifier associated with this request. If you want to repeat the same operation in an idempotent manner then you must include this value in the `clientToken` request parameter of that later call. All other parameters must also have the same values that you used in the first call.  
Type: String

 ** [permissionStatus](#API_DeletePermissionVersion_ResponseSyntax) **   <a name="ram-DeletePermissionVersion-response-permissionStatus"></a>
This operation is performed asynchronously, and this response parameter indicates the current status.  
Type: String  
Valid Values: `ATTACHABLE | UNATTACHABLE | DELETING | DELETED` 

 ** [returnValue](#API_DeletePermissionVersion_ResponseSyntax) **   <a name="ram-DeletePermissionVersion-response-returnValue"></a>
A boolean value that indicates whether the operation is successful.  
Type: Boolean

## Errors
<a name="API_DeletePermissionVersion_Errors"></a>

For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

The operation failed because the specified client token isn't valid.  
HTTP Status Code: 400
