4. Use Case

Zylker uses Zoho CRM to manage high-volume orders where customer phone numbers are sensitive data. The CRM Admin wants role-based phone number masking on the Orders List Page (Canvas). To improve visibility and speed, the Admin also wants color-coded order cards in the List View based on order status.

Role-Based Phone Number Visibility



Order Status Color Coding




5. Solution

  1. Go to Setup > Developer Space > Client Script. Click +New Script.
  2. Specify the details to create a script and click Next.



  3. Enter the following script and click Save.

  1. // Mask phone number based on user role
  2. if ($Crm.user.role.name === "Sales Executive") {

  4.     // Mask 7 digits for Sales Executive
  5.     ZDK.Page.getList().maskField("Phone_Number", {
  6.         length: 7,
  7.         character: "#",
  8.         reverse: true
  9.     });

  11. } else if ($Crm.user.role.name === "Support Agent") {

  13.     // Mask 10 digits for Support Agent
  14.     ZDK.Page.getList().maskField("Phone_Number", {
  15.         length: 10,
  16.         character: "#",
  17.         reverse: true
  18.     });
    }

  20. // Highlight cancelled orders in light red
  21. ZDK.Page.getList().style({
  22.         record: {
  23.             backgroundColor: "#FFD6D6"
  24.         }
  25.     },
  26.     "(Status:equals:Cancelled)"
  27. );

  29. // Highlight delivered orders in light green
  30. ZDK.Page.getList().style({
  31.         record: {
  32.             backgroundColor: "#D3F9D8"
  33.         }
  34.     },
  35.     "(Status:equals:Delivered)"
  36. );
  1. Use $Crm.user.role.name to retrieve the role of the currently logged-in user.
  2. When the role is Sales Executive, use ZDK.Page.getList().maskField() on the Phone_Number field to mask the first 7 digits, where 
    1. length defines how many characters should be hidden
    2. character: '#' specifies the masking symbol
    3. reverse: false ensures masking starts from the beginning, allowing partial visibility.
  3. When the role is Support Agent, use ZDK.Page.getList().maskField() on the Phone_Number field to mask all 10 digits, fully hiding the phone number using the same masking parameters.
  4. Use ZDK.Page.getList().style() to apply conditional styling to list records by configuring the record parameter to set the row backgroundColor.
  5. Apply the condition (Status:equals:Cancelled) to highlight cancelled records in light red, and (Status:equals:Delivered) to highlight delivered records in light green, enabling quick visual identification.

  6. Here is how the Client Script works for a "Sales Executive".



  7. Here is how the Client Script works for a "Support Agent".



  8. Here is how the Client Script works for a for other roles like, Manager and Admin.
