<p>Creates a case in the Amazon Web Services Support Center. This operation is similar to how you create a case in the Amazon Web Services Support Center <a href="https://console.aws.amazon.com/support/home#/case/create">Create Case</a> page.</p> <p>The Amazon Web Services Support API doesn't support requesting service limit increases. You can submit a service limit increase in the following ways: </p> <ul> <li> <p>Submit a request from the Amazon Web Services Support Center <a href="https://console.aws.amazon.com/support/home#/case/create">Create Case</a> page.</p> </li> <li> <p>Use the Service Quotas <a href="https://docs.aws.amazon.com/servicequotas/2019-06-24/apireference/API_RequestServiceQuotaIncrease.html">RequestServiceQuotaIncrease</a> operation.</p> </li> </ul> <p>A successful <code>CreateCase</code> request returns an Amazon Web Services Support case number. You can use the <a>DescribeCases</a> operation and specify the case number to get existing Amazon Web Services Support cases. After you create a case, use the <a>AddCommunicationToCase</a> operation to add additional communication or attachments to an existing case.</p> <p>The <code>caseId</code> is separate from the <code>displayId</code> that appears in the <a href="https://console.aws.amazon.com/support">Amazon Web Services Support Center</a>. Use the <a>DescribeCases</a> operation to get the <code>displayId</code>.</p> <note> <ul> <li> <p>You must have a Business, Enterprise On-Ramp, or Enterprise Support plan to use the Amazon Web Services Support API. </p> </li> <li> <p>If you call the Amazon Web Services Support API from an account that doesn't have a Business, Enterprise On-Ramp, 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/">Amazon Web Services Support</a>.</p> </li> </ul> </note>
