Google AdWords and promo codes

Question

Google

Before that, I had never done advertising, but recently, as a regular user of Google Analytics, I was given a promo code for 300 UAH. I registered a record, added a credit card to the prepaid mode, redeemed the promo code. As a result, 300 UAH hangs on the balance sheet, and the message says that I have exhausted all the money. There is a suspicion that it is true that you need to throw real money into the account, but you don’t want to test the functionality from your pocket))))
I didn’t find the answer in the help, maybe someone can help here? Thank you.

Answer 1

You need to deposit some amount into the account and the promo amount will be added to it. Details were written in a letter with a promo code.

Answer 2

to deposit 400 real rubles for coupons of 1000 rubles each (I was also delighted when I received 5 of them))))
