## Examples
<a name="API_UntagResource_Examples"></a>

If you plan to create requests manually, you must replace the Authorization header contents in the examples (`AUTHPARAMS`) with a signature. For more information, see [Signing AWS API requests](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-signing.html) in the *IAM User Guide*. If you plan to use the [AWS CLI](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/), these tools sign the requests for you.

### Example
<a name="API_UntagResource_Example_1"></a>

The following example removes the tag pair with the key name "environment" from the scalable target specified by its ARN.
