Deletes tags from a customer
managed key. To delete a tag, specify the tag key and the KMS key.
Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details,
see ABAC
for KMS in the Key Management Service Developer Guide.
When it succeeds, the UntagResource operation doesn't return any output. Also,
if the specified tag key isn't found on the KMS key, it doesn't throw an exception
or return a response. To confirm that the operation worked, use the ListResourceTags
operation.
For information about using tags in KMS, see Tagging keys. For general information about tags, including the format and syntax, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference.
The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the Key Management Service Developer Guide.
Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.
Required permissions: kms:UntagResource (key policy)

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginUntagResource and EndUntagResource.

| Exception | Condition |
|---|---|
| InvalidArnException | The request was rejected because a specified ARN, or an ARN in a key policy, is not valid. |
| KMSInternalException | The request was rejected because an internal exception occurred. The request can be retried. |
| KMSInvalidStateException | The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide. For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception. |
| NotFoundException | The request was rejected because the specified entity or resource could not be found. |
| TagException | The request was rejected because one or more tags are not valid. |
