# DescribeServices
<a name="API_DescribeServices"></a>

Returns the current list of AWS services and a list of service categories for each service. You then use service names and categories in your [CreateCase](API_CreateCase.md) requests. Each AWS service has its own set of categories.

The service codes and category codes correspond to the values that appear in the **Service** and **Category** lists on the Support Center [Create Case](https://console.aws.amazon.com/support/home#/case/create) page. The values in those fields don't necessarily match the service codes and categories returned by the `DescribeServices` operation. Always use the service codes and categories that the `DescribeServices` operation returns, so that you have the most recent set of service and category codes.

**Note**  
You must have an AWS Business Support\+, AWS Enterprise Support, or AWS Unified Operations plan to use the AWS Support API. If you're in an AWS Region that doesn't offer one of these AWS Support plans, or if you haven't transitioned to one of these plans, you can use the AWS Support API with a Business, Enterprise On-Ramp, or Enterprise Support plan.
If you call the AWS Support API from an account that doesn't have an AWS Business Support\+, AWS Enterprise Support, or AWS Unified Operations plan, the `SubscriptionRequiredException` error message appears. For information about changing your support plan, see [AWS Support](http://aws.amazon.com/premiumsupport/).
