Pass tag Key and Value for resource name in AWS Cloudformation

I have my cloudformation json template which has the resource(VPC to be specific) Tags mapped something like this:

"Tags" : [ {"Key" : "Name", "Value" : "nameofresource"} ]
Now I am running this from a shell script with the command

aws cloudformation create-stack --stack-name stackname --template-body file://template.json

I want to pass the name from the parameter. I tried it using

--parameters ParameterKey=Name,ParameterValue=somevalue

after my template. But it throws an error. Also I tried replacing the "Value" in the JSON with "Ref" : "paramkeyvalue" and passed it as required from the cli. How do I pass the name from parameters?

Replace the parameters Key and value name as ParameterKey and ParameterValue

--parameters ParameterKey=Name,ParameterValue=somevalue

"Tags" : [ {"ParameterKey" : "Name", "ParameterValue" : "somevalue"} ]
