Create ticket with attachment using Google Apps Script problem.

Hello,

I try to use google apps script to create ticket with attachments via API.

We have no google app script sample code with attachment yet.

I tried the following code, but it seems always return error by /helpdesk/tickets.json api.

how to do this right? (post a attachment in google app script with UrlFetchApp)

function createFreshdeskTicketWithAttachments() {

  

 var API_KEY = PropertiesService.getScriptProperties().getProperty('FreshDeskApiKey')

  if (!API_KEY) throw new Error('FreshDeskApiKey not found in script properties.')

  

  var ENDPOINT = Utilities.formatString('https://%s.freshdesk.com', 'zixia')

  

  var headers = {

    'Authorization': 'Basic ' + Utilities.base64Encode(API_KEY + ':X')

    , 'Content-type': 'application/json'

    //'Content-type': 'multipart/form-data'

  };



  var response = UrlFetchApp.fetch("https://circleci.com/gh/AKAMobi/ucapp/tree/master.svg?style=svg")

  var fileBlob = response.getBlob()

  Logger.log("%s:%s"

             , response.getResponseCode()

             , fileBlob.getContentType()

            )

    

  var payload = {

    helpdesk_ticket: {

      description: 'TEST 4'

      , subject: "TEST 4"

      , email: "test@test.com"

      , priority: 1

      , status: 2

      , attachments: { '': [ { resource: fileBlob } ] }

    }

  } 

  

  //Adds the extensions that are needed to post a new ticket to the end of the url

  var url = ENDPOINT + '/helpdesk/tickets.json';

  

  var options = {

    'method': 'post',

    'headers': headers,

    'payload': JSON.stringify(payload),

//    'payload': payload,

    muteHttpExceptions: true

  };

  

  var response = UrlFetchApp.fetch(url, options);

  

  Logger.log('resp: %s, %s'

             , response.getResponseCode()

             , response.getContentText()

            )



}
