title: GMB API - Payload schema for notification (pub/sub)
body: <p>We are working with a google my business integration.</p>
  <p>The API documentation is pretty exhaustive, except for the notification schema used on pub/sub.
  we are unable to find the correct information.</p>
  <p>Does anybody know what the data looks like?</p>
