Does Netflix automatically withdraw money from my account?

If I choose direct debit as the payment method at Netflix and provide my IBAN, does Netflix automatically withdraw the money from my account? Or do I have to do something extra?

Yes book yourself.

The money is always debited automatically.

With direct debits, debits are always made automatically. You give permission.

They book themselves. You don't have to do anything now, except to ensure that there's always enough money in your account.
