I am new to QuickBooks APIs. I'm unsure how to connect QuickBooks Online Company (https://quickbooks.intuit.com/#) with an Intuit Developer Account.

I already have a QuickBooks Account now. I created an Intuit Developer Account, but when I used the same email ID as QuickBooks, I thought my QuickBooks company would appear in the Intuit Developer Account; however, it did not. What steps do I need to take now?
