title: Unable to create offline conversion data set
body: <p>Having some difficulties creating offline data sets for third party clients. Any assistance would be greatly appreciated</p>
  <p>My app has received approval for ads_management advanced access.</p>
  <p>I've tried creating a data set for third party client. The query works when not using a third party client.</p>
  <p>Followed guide: <a href="https://developers.facebook.com/docs/marketing-api/offline-conversions/#create-event" rel="nofollow noreferrer">https://developers.facebook.com/docs/marketing-api/offline-conversions/#create-event</a></p>

  <p>mentions that create is not possible with endpoint</p>
  <p>Also followed steps at <a href="https://developers.facebook.com/docs/marketing-api/error-reference/" rel="nofollow noreferrer">https://developers.facebook.com/docs/marketing-api/error-reference/</a> on how to fix error code 100 subcode 33</p>
  <p>Is there an email for me to directly be in contact with a representative from facebook as there doesn't seem to be any response by asking for help on their developer support community platform.</p>
