Access parent response as plain text

Some times the response from a parent is a token in plain text that is needed to send with the child request to update some resource in the remote system.

To access a plain text in the child use {{body}} syntax

Parent POST /remotehost/gettoken respond with a token example: tdyfuiwojfwpiojfpewjfpfjwepojfwewfe

Child POST /remotehost/createsomething?token={{body}}
