Why do I get this 501 Not Implemented error?

Question

I am performing the following AJAX call:

$(document).ready(function() {

  $.getJSON(\'https://sendgrid.com/api/user.stats.json\',
    {
      \'api_user\':

As this is the top Google match for "jQuery 501 (Method not implement)" I thought I'd share what worked for me when experiencing this on the same domain (which is not your problem).

My problem was that I was not returning valid JSON, I was just returning "1". So to fix this, either:

• Ensure you return valid JSON, or if you don't require a JSON response,
• Swap your call to use $.ajax instead of $.getJSON, or
• If you're already using &.ajax, remove type: "json"

Hope that helps some people.
