UNIPaaS Gateway Setup Guide
Last updated on Sep 17, 2026
Connect UNIPaaS to Advanced Billing to process credit card transactions in USD and CAD.
Private key
UNIPaaS issues the private key that authorizes Advanced Billing to charge through your gateway. Generate it in the UNIPaaS business gateway, not in Maxio.
To get a Private Key
- Log in to your UNIPaaS business gateway.
- Go to Account > Settings.
- Click Generate Key.
- Copy the key into the password field of your payment gateway configuration in Advanced Billing.
Requirements
Even if the product doesn't require an address, the UNIPaaS gateway requires the country to be entered on the payment form.
Currencies and merchant location
For complete currency and merchant location support information, see the payment gateway overview page.
Data portability policy
Contact UNIPaaS for more information.
