Creating response json block based on the API result

[bharatid]

How to create response json block based on the API result which is in json format. Tried many ways from the doc I have seen, still get failure.
My tavern test:

# ===================================================================
# New Business Partner (BP) and full-setup, similar to full-setup.rtt
# ===================================================================
# Testing deployment, 220221, 10:47
includes:
  - !include config/common.yaml

test_name: Tavern POC, SAS-2279, New Business Partner/Customer, full setup, and NSQ

# Additional keys in JSON and headers OK
strict:
 - headers:off
 - json:off
 #- response:off    Does not work

marks:
  # For Shipwire Api calls, hostname on which the test is run is needed
  - usefixtures:
      - get_randomstr_len1
      - get_randomstr_len10
      - get_host_name

# Create SAP customer using endpoint which uses Recurring Billing APIs
stages:

  # SignIn
  - name: Signon Using the Newly Created Business Partner/Customer using SW API
    request:
      url: http://merchant.developer.corp.shipwire.com/data/auth
      method: GET
      json:
        user: aee99fbea4d14b619fe5929ae118595f+fakedev_shipwire_net+fakedev@shipwire.net
        pass: Ingram?123
      headers:
        Content-Type: application/json
    response:
      status_code: [200]
      json:
        code: !anystr
        message: !anydict
        url: !anystr
        result: !anydict    
        state: !anylist
      #headers:
      #cookies:
      #  - PHPSESSID
      #  set_cookie: 
      #    PHPSESSID: !anystr
      #  content-type: application/json
      #- __swCustomerPreferences

The response, got 200:
