Multifunction POST method in apex REST API controller

Question

I want to create a single POST method which takes method as a parameter along with the Request body. Using the parameter string method i'm trying to call the related method within my apex controller. But everytime I call this REST API using workbench and passing the method value i'm getting null value for method.

**

@RestResource(urlMapping='/AutomationSFEndPoint/*')
    global without sharing class Automation_SFEndPoint{
        @HttpPost
        global static String handleMethod(string method){
            if(method == 'Create_something'){
                //have some logic
            }
            if(method == 'Create_somethingElse'){
                //have some logic
            }
        }
    }
    //debug log for method is coming null every time

Answer 1

In order for this to work, you need to format your request in a very specific way. First, the Content-Type header must be set to application/json or application/xml. Then, you must provide the appropriate JSON or XML:

JSON

{ "method": "Hello World" }

XML

<request>
  <method>Hello World</method>
</request>
