Question:
Can the entire web service response be stored in a global variable/Index field in a Workflow?
Answer:
An entire Web Service response cannot be written to a global variable or Index Field; however, the keys of the JSON response can be written to global variables.
For example, when sending a request to our Intelligent Document Processing web service, you can capture the response data into Global Variables/Index Fields by defining the exact path from the JSON path that's returned.
