How to update API Version that is being called for CloudWatch?

Question

I'm using API Gateway to integrate with CloudWatch and when using majority of actions I get the following error message as the returned response.   
  
{  
  "Error": {  
    "Code": "InvalidAction",  
    "Message": "Could not find operation DescribeAlarms for version 2009-05-15",  
    "Type": "Sender"  
  },  
  "RequestId": "828bf814-a81a-41d2-8560-f1f64b81d977"  
}  
  
This is happening as the API Version it should be using is 2010-08-01, I tried updating the HTTP Header with X-Amz-Target and putting 'GraniteServiceVersion20100801.DescribeAlarms' as the value in Integration Request but nothing changed.

Answer

Under Method Integration -> URL Query String Parameters > I added Version as the name and '2010-08-01' as the value.  
  
All actions are now working as expected.
