This is a really simple NODE webapp that you can use to test Paystack's sample mobile apps.
It has only 2 endpoints
/verify/:reference which verifies a transaction, returning the gateway response.
/new-access-code which starts a new transaction and returns a fresh access code.
This is intended as a sample only: you'll likely need something more serious for your production apps.
