Do i need to create a second Test account and link that to the Test Manger Account to test AdWords API

Hey, This is what I have done so far: * created a Production Manager Account and used it to generate *client ID*, *client secret* and *Developer token* * created a Test Manager Account and generated the refresh token, by using OAuth mechanism. (In the OAuth flow I gave access to this account)

Re: MCC test account confusion, account works but client account gives USER_PERMISSION_DENIED

So does this mean, we have to create another Test account and then link it to the Test Manager Account to test API ? And also, Is this test account going to be another Test Manager account, because, I don't see any way to create a Test Account, which is not a manager On Friday, 28 February 20
