Query Request: EC2 Version

In StartInstances - Amazon Elastic Compute Cloud Amazon describes how to make a request to Start Instances of EC2 service.

To write the parameters of request with a Signature Version 4, I followed Common Query Parameters - Amazon Elastic Compute Cloud but I don't find the version to use.

I wonder if the version is strictly required in an API_StartInstances and where can I look for it? What is the last version valid for a StartInstance and other EC2 actions? Will there be a specific version for each EC2 command? At the moment I tried the version that I found in Query Requests - Amazon Elastic Compute Cloud:

GET
https://ec2.amazonaws.com/?Action=StartInstances
&InstanceId.1=i-1234567890abcdef0
&Version=2016-11-15
&AUTHPARAMS
Solution

  • I found the lastest EC2 Version that is 15-11-2016 and the list in https://docs.aws.amazon.com/it_it/AWSEC2/latest/WindowsGuide/DocumentHistory.html.
