Google App Script connection returning error 401

Question

I'm using a google script to connect to an external API with the code:

  var url='https://app.ecwid.com/api/v1/XXX/orders'

  var parameters = { method : 'get',
                    headers : {'Authorization': 'Bearer '+'yyy'}, 
                    contentType:'application/json',                   
                    muteHttpExceptions:true};

  var response = UrlFetchApp.fetch(url,parameters).getContentText();

  Logger.log(response);

But why is this returning the following error?

HTTP ERROR 401
Problem accessing /api/v1/XXX/orders. Reason:
    Unauthorized

Answer 1

Try removing the contentType from parameters and give it a shot.

For cross-domain requests, setting the content type to anything other than

• application/x-www-form-urlencoded
• multipart/form-data
• text/plain

will trigger the browser to send a preflight OPTIONS request to the server.
