SOAP requests

We have deprecated the SOAP API for Amazon EC2. As of 1 December 2015, we no longer support SOAP requests for any version of the API. If you use a SOAP request you receive the following response:

Client.UnsupportedProtocol: SOAP is no longer supported.

Similarly, the Amazon Software Development Kits (SDKs) no longer support SOAP requests for any version of the API.

We recommend that you use the Query API for Amazon EC2, or the Amazon SDKs. For more information, see Making requests to the Amazon EC2 API.
