Sending Zendesk ticket to salesforce

I want to send Zendesk ticket to Salesforce. I have used http target option in extension in zendesk and set the url of my visualforce page (Url: https://c.ap4.visual.force.com/apex/restOutput) and also enabled the Basic Authentication. When i send the test data from zendesk no logs are generated in salesforce developer console. The response sent by zendesk after sending the test data.

My visual page code is as follows: `

<apex:page controller="myController">
</apex:page>

My controller is defined as

@RestResource(urlMapping='/restOutput')
global class myController {
    public myController(){
        System.debug('constructor');
       callBack();
    }
    @HttpPost
    global static void callBack()
    {
        RestRequest req = RestContext.request;
        RestResponse res = RestContext.response;
        System.debug(req.requestBody);
        //System.debug(ApexPages.currentPage().getParameters());
    }
}

Solution

Finally i got the solution, I was making mistake in consuming the api. To consume the salesforce api, send a post request with authorization header(containing access token),post data. The Request seems similar to.

  curl --request POST \
  --url https://ap4.lightning.force.com/services/apexrest/restOutput \
  --header '<access_token or sessionID' \
  --data '{\n"ticket_title":"Workbench Api Request Test",\n"ticket_description":"This is just a test Description",\n"ticket_status":"New",\n"requester_firstname":"Ebizon",\n"requester_lastname":"NetInfo",\n"requester_email":"[email protected]"\n}\n'
