I have just created "Data Deletion Request Callback". I have filled in "Data Deletion Request URL" as described here https://developers.facebook.com/docs/apps/delete-data. When I remove my App from https://www.facebook.com/settings?tab=applications§ion=active ,"deauthorize" request from facebook is sending to my server....but when I try to send data deletion request, nothing happens, facebook isn't sending request to my server, but show me info "Unable to confirm request was received"
same issue i am also getting. kindly share if u find any solution
I solved my problem by getting the data by $signed_request = $request->query->get("signed_request");
as I noticed facebook sends the information by form-data
Same problem here, did you find any solution to this?
Seems this is worst than I thought :/ So many complicated steps with unreliable notification callbacks
