Making requests to the Amazon EC2 API
Important
As of October 14, 2022, HTTP responses from
the Amazon EC2 APIs no longer include a reason-phrase element. As recommended by
RFC7230
We provide the Query API for Amazon EC2, as well as software development kits (SDK) for Amazon that enable you to access Amazon EC2 from your preferred programming language. For more information, see the Amazon EC2 Developer Guide.

Required knowledge

-
XML

Web services
-

One or more programming languages, such as Java, PHP, Perl, Python, Ruby, C#, or C++.
Available APIs for Amazon EC2
The Amazon EC2 Query API provides HTTP or HTTPS requests that use the HTTP verb GET or POST
and a Query parameter named Action
.
Amazon provides libraries, sample code, tutorials, and other resources for software developers who prefer to build applications using language-specific APIs instead of submitting a request over HTTP or HTTPS. These libraries provide basic functions that automatically take care of tasks such as cryptographically signing your requests, retrying requests, and handling error responses, so that it is easier for you to get started.
For more information, see Create Amazon EC2 resources using an Amazon SDK in the Amazon EC2 Developer Guide.
