HttpRequest req = new HttpRequest();
req.setEndpoint('callout:aws_WScallout/alpha/plan/5?Source=Ops&localen=NA');
req.setMethod('GET');
Http http = new Http();
HTTPResponse res = http.send(req);
while (res.getStatusCode() == 302) {
res.setEndpoint(res.getHeader('Location'));
res = new Http().send(req);
}
System.debug(res.getBody());

- req.setHeader('x-amz-access-token', token);
- req.setHeader('Authorization', EncodingUtil.base64Encode( Blob.valueof('x-amz-access-token'+ token)));
- req.setHeader('x-amz-access-token', EncodingUtil.base64Encode(Blob.valueof(token)));

I used postman, where request works. I am setting the header with x-amz-access-token = token
1)Please check whether the accesstoken is deserilized in the correct way from the programming, which may includes extra characters while deserilzing the data.
2)Use Advanced Rest client tool,(ARC) i has more features to see the exact error or exception.
3)Pass the values statically using the anonymous window.
4)Give the header key and value in the correct format .
Finally , 1)please check weather the url provided for u was exposed as global...
Thank you..!
