Is amex the only credit card that intergrates with banking

QuickBooks support 20,000+ local and international banks, @geolen. That said, AMEX is not only the credit card that integrates with our banking feature. 

I'm happy to walk you through the steps to see if your Financial Institution (FI) is supported by QuickBooks Online banking. This way, you can connect it and manage your transactions anytime.

Bank feeds save time, so you don't have to enter anything manually. Once you connect your accounts, transactions will download and categorized. All you have to do is approve them. Follow the steps below to check our supported FI: 

1. Go to the Banking menu on the upper left side. 
2. Select the Link Account tab. 
3. Type your bank's name or URL in the search box. 

If you see, then it's supported in QuickBooks. If you're ready to connect, you can browse this article for complete steps: Connect bank and credit card accounts to QuickBooks Online.

If you don't see it, be aware that a financial institution may have multiple bank names or different types of accounts. But will only publish one website to set up a QuickBooks connection. For more details, see this link: Find your bank or credit card account when you connect to online banking.
