Pass an input variable as json, get an output as json, by hitting the REST API call

I am passing an input json variable for a process model. On hitting a REST API call, it should return an output variable, which needs to be captured.

@Kishore in which rest api you’re posting the request?

I am using Python to create REST API and using Postman API Client. I want to check it.

What i need is…I am passing an input variable as input to a REST API call. The output from the REST API call i need to print on the process model or pass that output as input to another REST API call

which camunda rest endpoint you’re using?
