Zoho CRM Workflow Function Not Receiving Field Data – All Values NULL

Hi Everyone,

I am trying to do an automation using function and workflow.

One of our client has a request that they want to get an update about all of their sales order on their application when the status of sales order change. I created a work flow rules, crete and edit and if the account name is "client account name", then apply the function.

An automated category functuion is created to send

SO_Number, Status, Deal_Name,Contact_Name to a

webhook url. later will be replaced by clients standard Mule Rest Callout with auth2.0 authentication.

my response is success but no data is sent all logs are showing data point is null. I have fot the fields name and API name from Zoho API names only.

Info

🔍 Function Execution Started
Received SO Number: NULL

Received Account Name: NULL or Empty
string standalone.sendSalesOrderToMule(Int sales_order_id)
{
// Fetch Sales Order details from Zoho CRM
sales_order = zoho.crm.getRecordById("SalesOrders",sales_order_id);
// Check if the Account Name is "Aldar Properties"
account_name = sales_order.get("Account_Name");
if(account_name != "Aldar Properties")
{
return "No action taken - Not Aldar Properties";
}
// Extract required fields
so_number = sales_order.get("SO_Number");
status = sales_order.get("Status");
deal_name = sales_order.get("Deal_Name");
contact_name = sales_order.get("Contact_Name");
// Prepare JSON payload
data_map = Map();
data_map.put("so_number",so_number);
data_map.put("status",status);
data_map.put("deal_name",deal_name);
data_map.put("contact_name",contact_name);
// Convert Map to JSON string
json_payload = data_map.toString();
// Ensures proper JSON format
// Define Webhook URL (For now, we use a dummy API for testing)
webhook_url = "https://httpbin.org/post";
// 🔄 Replace with MuleSoft API later
// Send POST request
response = invokeurl
[
url :webhook_url
type :POST
parameters:json_payload
headers:{"Content-Type":"application/json"}
];
// Log response for debugging
info response;
// Return success message
return "Webhook sent successfully!";
}
❌ Error: Account Name is empty!
