Amazon Glacier supports a set of operations—specifically, a set of RESTful API calls—that enable you to interact with the service.
You can use any programming library that can send HTTP requests to send your REST requests to Amazon Glacier. When sending a REST request, Amazon Glacier requires that you authenticate every request by signing the request. Additionally, when uploading an archive, you must also compute the checksum of the payload and include it in your request. For more information, see Signing Requests.
In the event of an error, You need to know what Amazon Glacier sends in an error response so that you can process it. This section provides all this information, in addition to documenting the REST operations, so that you can make REST API calls directly.
You can either use the REST API calls directly or use the AWS SDKs that provide wrapper libraries to simplify your coding task. These libraries sign each request you send and compute the checksum of the payload in your request. Therefore, using the AWS SDKs simplifies your coding task. This developer guide provides working examples of basic Amazon Glacier operations using the AWS SDK for Java and .NET. For more information see, Using the AWS SDKs with Amazon Glacier.
