I’ve tried hashes with all of the field in this order, different orders, as well as just the last three fields thinking that these are standard ones sent by Twitter so they should work. No combination of what I have tried with the submitted information to these fields has worked. Is there a specific order that I’m missing? Any help would be appreciated.
