how to call apex class from process builder

that apex class using update the record fields
Khan AnasKhan Anas (Salesforce Developers) 
Hi Prasad,

Greetings to you!

To use this action in a process, ask your developer to annotate the appropriate method with @InvocableMethod. 
  1. The Apex class and the process are executed by the user whose action triggered the process. Enter a name for this action. This text appears on the canvas and helps you differentiate this action from others in your process. The name truncates to fit on the canvas.
  2. Choose an Apex class by entering the name of the class to filter results or select a class from the drop-down list.
  3. If the class includes an invocable variable, you can manually enter values or reference field values from a related record.
The value must match the variable’s data type. You can set values for sObject and primitive type list variables only.
  • To set values for sObject variables and sObject list values, reference an object’s related records, for example, all child contact records associated with the Account object that started the process.
  • To set a value for a primitive list variable (String, Integer, Time, and so on), select the String value type and enter a value in the text input field. You can’t pass multiple values to lists.
      4. Click Save.
