Question

I have everything working except the actual file is not readable. I assume it loads since I dont get any errors and the attachment is created. The “file” needs to be base64 in salesforce so I am assuming my problem is that the blob in Drive is not base64. The question is, how do I convert the file blob to a base64 format for uploading, and will this actually work.

Relevant Code chunks

    var payload =  Utilities.jsonStringify(
      {"Name" : name, //string
       "ParentId" : acctId,  //string
       "OwnerId" : ownerId,  //string
       "body" : content  //base64
      }
    );

    var contentType = "application/json; charset=utf-8";
    var feedUrl = instanceUrl + "/services/data/v23.0/sobjects/Attachment/"
    var response = UrlFetchApp.fetch(feedUrl, { method : "POST", headers : { "Authorization" : "OAuth " + accessToken }, payload : payload, contentType: contentType });

    var feed = JSON.parse(response.getContentText());

looking at it here it seams the Utilities.jsonStringify() the file would be an issue. Still need some help making this work though.

The code snippet below works for me. I re-wrote it a bit to fit my sample. I didn’t include an ownerid as I didn’t know what to include there. I think the key issue might be that you didn’t use getAs(). If you got pure Google Doc blob then your browser won’t know how to convert that. Notice, how I used application/pdf. I believe you can use a similar MIME type for MS Word as well. Also note that I converted to Base64 using the Utilities API.

var myFileId = 'MY_FILE_ID';
var myParendId = 'ACCOUNT_ID';
var myToken = 'USER_TOKEN';

var baseContent = DocsList.getFileById(myFileId).getAs('application/pdf').getBytes();
var base64Content = Utilities.base64Encode(baseContent);

var payload =  Utilities.jsonStringify(
  {"Name" : 'ArunTest.pdf', //string
   "ParentId" : myParendId,  //string
   "body" : base64Content  //base64
  }
);

var options = {
        "method": "post",
        "contentType" : "application/json",
        "payload" : payload,
        "headers" : {
                     "Authorization" : "Bearer " + myToken
                    }
}

var getDataURL = UserProperties.getProperty(baseURLPropertyName) + '/services/data/v26.0/sobjects/Attachment/';
var dataResponse = UrlFetchApp.fetch(getDataURL,options).getContentText();
