## Examples


In the following example or examples, the Authorization header contents( `AUTHPARAMS` ) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) in the *AWS General Reference*.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the [AWS Command Line Interface (AWS CLI)](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/) to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

### Example


This example updates the default outbound calling name for the administrator's AWS account.

#### Sample Request


```
PUT /settings/phone-number HTTP/1.1 Host: service.chime.aws.amazon.com Accept-Encoding: identity User-Agent: aws-cli/1.16.170 Python/3.6.0 Windows/10 botocore/1.12.160 X-Amz-Date: 20191028T185642Z Authorization: AUTHPARAMS Content-Length: 25 {"CallingName": "myName"}
