Using ZRC in Client Script

Using ZRC in Client Script

Hello everyone!

Welcome to another week of Kaizen. In today's post, lets see what is ZRC (Zoho Request Client) and how we can use ZRC methods in Client Script to get inputs from a Salesperson and update the Lead status with a single button click.

1. What is ZRC?

Zoho Request Client (ZRC) is a built-in SDK in Zoho CRM that provides a unified way to make REST API calls across developer-centric features of Zoho CRM like Client Script, Widgets. Invoking CRM APIs, Connection APIs, and external APIs requires different syntax and separate code for each type. ZRC removes this complexity by offering one common and consistent approach to call all APIs, making client-side development easier and faster.

The following are the key features of ZRC.
  1. ZRC works with any CRM API version
  2. It supports self domain calls by providing only the API endpoint without specifying the domain
  3. Uses a single unified syntax for CRM APIs, custom Connections, and external public APIs. 
  4. No authentication handling needed for the same CRM org as ZRC manages it automatically
  5. Automatic JSON handling without manual parsing.
  6. Supports clean async code with full async-await and promise chaining.

3. Use Case - Log call notes and update the Lead status with a button click.

Quote
At Zylker, Salespersons often make multiple call attempts before connecting with a lead. Manually recording these attempts and updating the Lead status is often overlooked, leading to incomplete tracking and inaccurate pipeline data. To address this, the Admin wants the following changes:

1. Display a popup to capture call attempt details when a button is clicked and save them as a Note on the current Lead.

2. Also, update the Lead_Status of the current Lead to “Contacted” .

4. Solution

Here, the requirement is to create a note based on the Salesperson's description and update the status of the Lead record.To achieve this, Salesperson's input is collected through a pop-up when a custom button is clicked. The ZRC POST method is used to create a note for the Lead. The ZRC PUT method is used to update the status of the Lead record. As the Client Script has to be triggered with a button click, you should create a custom button and add Client Script from "Create Custom Button" pop-up.

  1. Go to Setup > Customization > Modules and Fields. Click Leads and navigate to "Buttons" tab.
  2. Specify the details about the custom button, Define action as "Client Script" and click Create.


  1. This opens Client Script IDE.
  2. Enter the following script and click Add in Client Script IDE. 
  1. // Validate if the script is running on a Lead record page
  2. if (!leadModule || !leadRecordId || leadModule !== 'Leads') {
  3.     ZDK.Client.showMessage('This script is designed to run exclusively on Lead record pages. Please navigate to a Lead record to use this feature.', { type: 'warning' });
  4.     return;
  5. }

  7. // Display a loader to indicate ongoing background operations
  8. ZDK.Client.showLoader({ message: 'Logging call attempt and creating follow-up actions...' });

  10. try {
  11.     // 1. Create a standardized Note attached to the Lead
  12.     var notes_content = ZDK.Client.getInput([{
  13.         type: 'text',
  14.         label: 'Log Call Details'
  15.     },
  16.     ], 'Log Call Details', 'OK', 'Cancel');
  17.     log(notes_content);
  18.     console.log({ notes_content });
  19.     const notePayload = {
  20.         data: [{
  21.             Note_Title: 'Call Attempt Log',
  22.             Note_Content: notes_content[0],
  23.             Parent_Id: { // Associate the note with the current Lead record
  24.                 id: leadRecordId,
  25.                 name: leadRecordName,
  26.                 module: {
  27.                     api_name: leadModule
  28.                 }
  29.             }
  30.         }]
  31.     };

  33.     const noteCreationResponse = await zrc.post('/crm/v8/Notes', notePayload);

  35.     // Check for successful note creation (200 OK or 201 Created)
  36.     if (noteCreationResponse.status !== 201 && noteCreationResponse.status !== 200) {
  37.         throw new Error('Failed to create Note: ' + JSON.stringify(noteCreationResponse.data));
  38.     }

  40.     // 2. Update the Lead_Status field to “Contacted” on the current Lead
  41.     const leadUpdatePayload = {
  42.         data: [{
  43.             id: $Page.record_id, // Specify the record to update
  44.             Status: 'Contacted'
  45.         }]
  46.     };
  47.     const leadUpdateResponse = await zrc.put(`/crm/v8/${leadModule}/${leadRecordId}`, leadUpdatePayload);
  48.     $Client.refresh();

  50.     // Check for successful lead status update (200 OK or 202 Accepted)
  51.     if (leadUpdateResponse.status !== 200 && leadUpdateResponse.status !== 202) {
  52.         throw new Error('Failed to update Lead Status: ' + JSON.stringify(leadUpdateResponse.data));
  53.     }

  55.     // Display a success message
  56.     ZDK.Client.showMessage('Call attempt logged, and Lead status updated', { type: 'success' });

  58. } catch (error) {
  59.     // Log and display an error message if any step fails
  60.     console.error('Error executing Log Call Attempt script:', error);
  61.     ZDK.Client.showMessage(`An error occurred: ${error.message}`, { type: 'error' });
  62. } finally {
  63.     // Always hide the loader, regardless of success or failure
  64.     ZDK.Client.hideLoader();
  65. }

  1. In the above script, $Page.module retrieves the current CRM module from which the script is executed.
  2. $Page.record_id fetches the unique ID of the record currently opened on the page.
  3. $Page.record provides access to the field values of the current record.
  4. ZDK.Client.showLoader() displays a visual loading message to inform the Salesperson that background operations are in progress.
  5. ZDK.Client.getInput() prompts the Salesperson to enter details about the call through an input dialog.
  6. ZRC.post() sends a POST request to Zoho CRM to create a new record and automatically handles authentication and domain resolution.
  7. In the notePayload,"Parent_Id" links the created note to the current CRM record and module.
  8. ZRC.put() sends a PUT request to Zoho CRM to update an existing record.
  9. $Client.refresh() refreshes the current CRM page so the latest updates are immediately visible to the Salesperson.
  10. Here is how Client Script works.
