Hi, variable extractors can be used to extract values from JSON responses and store those values in variables. For the requests, you can edit the payload like this

{"password":${varPassword},"email":${varEmail}}

where ${myvariablename} is the variable

...here is the help link for variable extraction, the what's new in 6.1 also mentions JSON. hope it helps
