IAM identifiers

• Note When you use ARNs to identify resources in an IAM policy, you can include policy variables. Policy variables can include placeholders for runtime information (such as the user's name) as part of the ARN. For more information, see IAM policy elements: Variables and tags

Quotas, name requirements, and character limits

• Note To get account-level information about IAM usage and quotas, use the GetAccountSummary API operation or the get-account-summary AWS CLI command.

Signing AWS API requests

• Important If you use an AWS SDK or AWS command line tool to send API requests to AWS, these tools sign the API requests for you. You must only sign AWS API requests as described in this documentation if you do not use an AWS SDK or AWS command line tool to send AWS API requests.
