Using #set

You can use #set to define a variable that can be used within the template.

Our (original) template is as follows:

{  "name" : $input.json('$.user.name'),  "time": $input.json('$.greeting.time') }

The template, when rewritten by using #set, is as follows:

#set($inputRoot = $input.path('$')){  "name" : "$inputRoot.user.name",  "time": "$inputRoot.greeting.time"}

The $inputRoot is also the variable name that is autogenerated by API Gateway in the AWS Management Console. However, you are free to use any name.
