Can I accept Union Pay through QB?

Hi there,

It's good you're using the Online Payments feature in QuickBooks. I'd be glad to answer your question. 

At this time, QBO Payments only accepts Mastercard, Visa, Apple Pay and Discover. I recommend you to take a look at third-party apps such as PayPal which you can ingrate with QBO. To search for the apps which allow you to integrate your Payment Processor with QBO, visit www.apps.com and enter the name of the Payment Processor you're using. 

If you have further questions about this, don't hesitate to reach out. I'm here to make sure you're all set. I'll be on standby. :)
