Hi Rahul, This is because the plugin is returning null. I can't tell which JSON object name you're passing, but the plugin works by expecting specific key names from the response and retrieving values matching those exact keys before saving them to variables or forms. In your case, it's returning null or an empty string because it can't find the key you specified i.e. the whole response.

Here's a better solution: Use the Enhanced JSON API Tool instead, which lets you format the response before storing it in workflow variables or forms.

Enable the "Format Response" option and use this beanshell code. This code converts your API data into a JSON string and stores it in a map with the key "response" - this lets you capture the entire API response in your workflow variable by using "response" as the JSON Object Name.

I have also attached the app for your reference. Hope this helps!!

import org.joget.workflow.model.service.*;
import java.util.*; 
import org.joget.commons.util.LogUtil;
import org.json.JSONObject;
import org.json.JSONArray;

JSONObject jsonObject = new JSONObject(data); // Convert the data Hashmap to JSON string
String jsonString = jsonObject.toString();
LogUtil.info( "Original data map:----------- " , jsonString.toString());

Map formattedResponse = new HashMap(); 
formattedResponse.put("response", jsonString.toString());  // Store entire data object under "response" key and use this key to store the full response in wf variable

return formattedResponse;

hi Varnaa 

thanks for the idea, it did not strike me to  use the formating are to assign the value to variable.

i have used the below code to assign the value to workflow variable. atleaset i am getting the value in next tool to process the joson and insert it into table directly.

import org.joget.workflow.model.service.*;
import org.json.JSONObject;
import org.joget.commons.util.LogUtil;

// Save the API response directly into a workflow variable
WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");
wm.activityVariable(workflowAssignment.getActivityId(), "product_json", data.toString()); // Save the raw API response into the workflow variable

// Log the saved response for debugging
LogUtil.info("Save JSON API Response", "API response saved to workflow variable 'product_json': " + data.toString());

Hi Hugo 

I am trying to save the JSON response into workflow variable and use this variable in next tool to save JSON data in table (or may be also show in form) using beanshell. my JSON is complex so i need to use beanshell.

I have tried to show the problem using a sample json. the app is attached. 

The only way to get the JSON in workflow variable is to write the code in the "Format Response" script box.

Can you advise how i can directly save the JSON into workflow variable.

-----------work around Code Starts--------------

import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.LinkedHashMap;

// Parse JSON 
ObjectMapper objectMapper = new ObjectMapper();
LinkedHashMap<String, Object> orderedJsonMap = objectMapper.readValue(data.toString(), LinkedHashMap.class);

// Convert back to JSON string if needed
String orderedJsonString = objectMapper.writeValueAsString(orderedJsonMap);

// Save the ordered JSON string into the workflow variable
wm.activityVariable(workflowAssignment.getActivityId(), "wfv_json", orderedJsonString);

-----------work around Code Ends--------------
