What is a Custom Function?

For more information about Deluge scripting language, refer to Zoho - Deluge Scripting Language.

Custom Function for a service can be created in Settings > Select a Service > Automation > Actions > Custom Functions.

How Custom Function works in Zoho People

1. Create a Custom Function for a form in a service and associate it with a new or existing Workflow.
   
2. Whenever a Workflow trigger event occurs, the Custom Function executes, performing the specified actions as defined in your code.
   

Create Custom Function

1. From you home page, navigate to Settings > Select a Service > Automation > Custom Functions.
   
   
2. Click Add Custom Function.
   
3. Select the form for which you would like to create Custom Function.
   
4. Enter a name for the Custom Function.
   
5. Click Edit Parameters, define the method name, and specify the required method arguments by specifying the variable name and the corresponding field values.
   
   
6. Click Save.
7. Enter the description of the Custom Function.
   
8. Enter the Deluge code, for more information, refer to Zoho - Deluge Scripting Language
   
1. For Syntax auto-suggestion, enable Syntax Builder.
   
2. For Connections, refer to Connections.
   
9. Click Save.
   
   

   Click Save and Execute to test and run the script immediately.

Map the created custom function to a workflow to automatically run the code whenever a trigger event defined in the workflow occurs.

Map a Custom Function to Workflow

1. From your home page, go to Settings > Select a Service > Workflows > Add Workflow.
2. Provide all the required details, Learn more to configure Workflow.
3. Under Actions, click Custom Functions and click the (+) add icon to add a new custom function to the workflow or you can select the existing custom function which are created for the form.
   
   
4. Click Add.
   A workflow is created and based on the trigger events the custom function executes, performing the specified actions as defined in your code.

Use Cases

Automatic travel expense update using custom functions

1. From your home page, go to Settings > Select a Service (Travel) > Automation > Actions > Custom Functions.
2. Select respective Form (Travel Expense) and click  Add Custom Function.
3. Provide a Custom Function Name and required parameter details
4. Provide the script as given below.
   
5. Click Save  to save the Custom Function.
   

   Click Save and Execute to test and run the script immediately.

1. travelExpenseMap = zoho.people.getRecordById("travelexpenses",travel_id);
2. tabularList = travelExpenseMap.get("tabularSections").get("Expense");
3. totalExp = 0;
4. for each str in tabularList
5. {
6. totalExp = totalExp + str.get("Ticket").toDecimal() + str.get("Lodging").toDecimal() + str.get("LocalConveyance").toDecimal() + str.get("Boarding").toDecimal() + str.get("Others").toDecimal() + str.get("Incidentals").toDecimal() +str.get("Phone").toDecimal();
7. }
8. updateemp = Map();
9. updateemp.put("recordid",erecno);
10. updateemp.put("Total_Expense",totalExp);
11. updaterecord = zoho.people.update("employee",updateemp);
12. info updaterecord;
    

Automatically change the employee status from active to resigned during an employee's date of exit using Custom Functions

An employee is resigning his job and you want to change the status to 'Resigned' in the employee form during the date of exit. You can do this action using the below script in our custom function. By adding exit details for an employee, a workflow will be triggered where the mapped custom function will get executed. Upon successful execution, the selected employee's employee status value will be changed to 'Resigned'. Thus, the employee cannot log in to the organization account anymore.

1. getrecord = zoho.people.getRecordById("employee",erecno);
2. params = Map();
3. params.put("scope","creatorapi");
4. params.put("Employee_ID",empid);
5. params.put("First_Name",fname);
6. params.put("Last_Name",lname);
7. params.put("Email_ID",emailid);
8. pushrecord = invokeurl
9. [
   
10.   url: "https://creator.zoho.com/api/karenjohn/json/custom-function/form/Custom_form/record/add/"
11.     type: POST
12.     parameters: params
13.     connection : "cf"
14. ];
15. info pushrecord;
    

Automatic check out in Attendance module

Let us consider a scenario, where an employee forgets to do check out on the system at the end of the day. It is possible to use Custom Functions to do an Auto-check out on the system. This helps in tracking the exact working hours of an employee.

Use the following parameters for both the methods mentioned below.

Method 1: When the check out is not done, Custom Functions can be used to update the respective shift's end time as the check out time on the system.

Steps:

1. From your home page, go to Settings > Select a Service > Automation > Actions > Custom Functions.
2. Select respective Form and click  Add Custom Function.
3. Provide a Custom Function Name and required parameter details
4. Provide the script as given below.
   
5. Click Save to save the Custom Function
   
   

   Click Save and Execute to test and run the script immediately.

Automatic check-out custom functions can be used only when all employees in the organization belong to the same time zone.

The above scripts can also be edited and used to serve other similar scenarios.

All APIs used in Custom Functions have threshhold limits. Refer the API guide for the limits under each module and customize the code accordingly.
