CreateCase - AWS Support


Creates a case in the AWS Support Center. This operation is similar to how you create a case in the AWS Support Center Create Case page.

The AWS Support API doesn't support requesting service limit increases. You can submit a service limit increase in the following ways:

A successful CreateCase request returns an AWS Support case number. You can use the DescribeCases operation and specify the case number to get existing AWS Support cases. After you create a case, use the AddCommunicationToCase operation to add additional communication or attachments to an existing case.

The caseId is separate from the displayId that appears in the AWS Support Center. Use the DescribeCases operation to get the displayId.

  • You must have a Business, Enterprise On-Ramp, or Enterprise Support plan to use the AWS Support API.

  • If you call the AWS Support API from an account that doesn't have a Business, Enterprise On-Ramp, or Enterprise Support plan, the SubscriptionRequiredException error message appears. For information about changing your support plan, see AWS Support.
