Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Application ID

A single Amazon Web Services account can be used by multiple customer applications to make calls to Amazon Web Services. Application ID provides a way for customers to identify which source application made a set of calls using an Amazon Web Services account. Amazon SDKs and services don't use or interpret this value other than to surface it back in customer communications. For example, this value can be included in operational emails or in the Amazon Health Dashboard to uniquely identify which of your applications is associated with the notification.

Example of setting this value in the config file:

[default]
sdk_ua_app_id=ABCDEF

Linux/macOS example of setting environment variables via command line:

export AWS_SDK_UA_APP_ID=ABCDEF
export AWS_SDK_UA_APP_ID="ABC DEF"

Windows example of setting environment variables via command line:

setx AWS_SDK_UA_APP_ID ABCDEF
setx AWS_SDK_UA_APP_ID="ABC DEF"

If you include symbols that have a special meaning to the shell being used, escape the value as appropriate.
