aws Canonical query

I generate canonical query for sts.amazonaws.com based on https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html. Is it correct for parameters listed below ?

Version=2011-06-15&Action=AssumeRole&RoleArn=arn:aws:iam::123456789101:role/gp_developer_role&RoleSessionName=Test1c
