Welcome
The AWS Support API Reference is intended for programmers who need detailed information about the Support operations and data types. You can use the API to manage your support cases programmatically. The AWS Support API uses HTTP methods that return results in JSON format.
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
SubscriptionRequiredExceptionerror message appears. For information about changing your support plan, see AWS Support.
You can also use the Support API to access features for AWS Trusted Advisor
You can manage your support cases with the following Support API operations:
-
The CreateCase, DescribeCases, DescribeAttachment, and ResolveCase operations create Support cases, retrieve information about cases, and resolve cases.
-
The DescribeCommunications, AddCommunicationToCase, and AddAttachmentsToSet operations retrieve and add communications and attachments to AWS Support cases.
-
The DescribeServices and DescribeSeverityLevels operations return AWS service names, service codes, service categories, and problem severity levels. You use these values when you call the CreateCase operation.
You can also use the AWS Support API to call the Trusted Advisor operations. For more information, see AWS Trusted Advisor in the AWS Support User Guide.
For authentication of requests, Support uses Signature Version 4 Signing Process.
For more information about this service and the endpoints to use, see About the AWS Support API in the AWS Support User Guide.
