Json request to call flowable engine

Hi all,

I am new to flowable. i have a use case where a service is calling flowable engine and passing an input object (having 5 or more variables) as a json and my process is triggered to call another external service via REST. I am using http task to call RESTful API. I want to use few variables further in my process to call some other external service via REST. Can someone help me in that. Is it possible to pass those variables/parameters.

Process variables are stored until the instance is finished. So if you set them, they’ll be available later on in the process.
