Backward compatible API to reactivate the FairPay App service
Since the API upgrade of botc-wallet server, the somewhat spreaded and used FairPay android App (the merchants way to accept Fairpay cards and android wallets with detailed tickets) is not working. The App uses the old API and it was working fine after the last updates from the app developer.
To update the app with new api calls and refresh the playstore repos don't seem a fast solution (dev not available), so the way to bring up again the service might be to open endpoints in the new api to respond to the old api calls. At least to let the app log-in the server and then we see what else is needed to operate again.
Will be wonderful to fix this asap because there are some pending payments from cards in shops and cards pending to activate and recharge.
