%%
%% The AWS Support API reference is intended for programmers who need
%% detailed information about the AWS Support operations and data types. This
%% service enables you to manage your AWS Support cases programmatically. It
%% uses HTTP methods that return results in JSON format.
%%
%% <note> <ul> <li> You must have a Business or Enterprise support plan to
%% use the AWS Support API.
%%
%% </li> <li> If you call the AWS Support API from an account that does not
%% have a Business or Enterprise support plan, the
%% <code>SubscriptionRequiredException</code> error message appears. For
%% information about changing your support plan, see <a
%% href="http://aws.amazon.com/premiumsupport/">AWS Support</a>.
%%
%% </li> </ul> </note> The AWS Support service also exposes a set of <a
%% href="http://aws.amazon.com/premiumsupport/trustedadvisor/">AWS Trusted
%% Advisor</a> features. You can retrieve a list of checks and their
%% descriptions, get check results, specify checks to refresh, and get the
%% refresh status of checks.
%%
%% The following list describes the AWS Support case management operations:
%%
%% <ul> <li> <b>Service names, issue categories, and available severity
%% levels. </b>The <a>DescribeServices</a> and <a>DescribeSeverityLevels</a>
%% operations return AWS service names, service codes, service categories,
%% and problem severity levels. You use these values when you call the
%% <a>CreateCase</a> operation.
%%
%% </li> <li> <b>Case creation, case details, and case resolution.</b> The
%% <a>CreateCase</a>, <a>DescribeCases</a>, <a>DescribeAttachment</a>, and
%% <a>ResolveCase</a> operations create AWS Support cases, retrieve
%% information about cases, and resolve cases.
%%
%% </li> <li> <b>Case communication.</b> The <a>DescribeCommunications</a>,
%% <a>AddCommunicationToCase</a>, and <a>AddAttachmentsToSet</a> operations
%% retrieve and add communications and attachments to AWS Support cases.
%%
%% </li> </ul> The following list describes the operations available from the
%% AWS Support service for Trusted Advisor:
%%
%% <ul> <li> <a>DescribeTrustedAdvisorChecks</a> returns the list of checks
%% that run against your AWS resources.
%%
%% </li> <li> Using the <code>checkId</code> for a specific check returned by
%% <a>DescribeTrustedAdvisorChecks</a>, you can call
%% <a>DescribeTrustedAdvisorCheckResult</a> to obtain the results for the
%% check that you specified.
%%
%% </li> <li> <a>DescribeTrustedAdvisorCheckSummaries</a> returns summarized
%% results for one or more Trusted Advisor checks.
%%
%% </li> <li> <a>RefreshTrustedAdvisorCheck</a> requests that Trusted Advisor
%% rerun a specified check.
%%
%% </li> <li> <a>DescribeTrustedAdvisorCheckRefreshStatuses</a> reports the
%% refresh status of one or more checks.
%%
%% </li> </ul> For authentication of requests, AWS Support uses <a
%% href="https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html">Signature
%% Version 4 Signing Process</a>.
%%
%% See <a
%% href="https://docs.aws.amazon.com/awssupport/latest/user/Welcome.html">About
%% the AWS Support API</a> in the <i>AWS Support User Guide</i> for
%% information about how to use this service to create and manage your
%% support cases, and how to call Trusted Advisor for results of checks on
%% your resources.

%%
%% The AWS Support API doesn't support requesting service limit increases.

%% operation.
%%
%% </li> </ul> A successful <code>CreateCase</code> request returns an AWS
%% Support case number. You can use the <a>DescribeCases</a> operation and

%% additional communication or attachments to an existing case.
%%
