<p>Returns the current list of Amazon Web Services services and a list of service categories for each service. You then use service names and categories in your <a>CreateCase</a> requests. Each Amazon Web Services service has its own set of categories.</p> <p>The service codes and category codes correspond to the values that appear in the <b>Service</b> and <b>Category</b> lists on the Amazon Web Services Support Center <a href="https://console.aws.amazon.com/support/home#/case/create">Create Case</a> page. The values in those fields don't necessarily match the service codes and categories returned by the <code>DescribeServices</code> operation. Always use the service codes and categories that the <code>DescribeServices</code> operation returns, so that you have the most recent set of service and category codes.</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.
