Q:

Test email and password for Quick Books API Oauth authentication

I want to test connecting to Quick Books  using their API.  So I've set up everything I need.  When I click on a button and it gets me to a page where I should enter an email and a password.  I'd like to use their "test" email and password.  But I didn't find any anything about that?  Do they exist? 

A:

There is no "test" username and password.  
Either submit a support ticket to Intuit to get a free trial of QuickBooks Online, or just sign up for the 30-day QuickBooks Online free trial to test.
