Where can I find a license key to connect my business website to Quickbooks?

Welcome to the Community, @usermichael-stevenso.

We have a separate online forum called Intuit Developer Community. This is a place where customers, engineers, and product developers come together, discuss a variety of development topics, and answer integration questions.

I recommend signing up so that one of the specialists will be able to reach out to you and help integrate your website to QuickBooks Online (QBO).

Here's how:

1. Go to https://www.developer.intuit.com/app/developer/homepage.
2. Click the Ask a Question button.
3. Select either Sign in or Create Account.

Feel free to comment below if you have any other questions or concerns about QuickBooks. I'll be more than happy to help. Have a great day!

On which platform did you build your website? Do you have a webstore/eCommerce?
