When does stripe actually deduct money from credit card

Question

I am new in payment gateway; I can't seem to figure out when does a payment actually gets deducted. So once the all card details are successfull the code below gets executed:

public partial class Charge : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e) {
        if (Request.Form["stripeToken"] != null)
        {
            var customers = new StripeCustomerService();
            var charges = new StripeChargeService();

            var customer = customers.Create(new StripeCustomerCreateOptions
            {
                Email = Request.Form["stripeEmail"],
                SourceToken = Request.Form["stripeToken"]
            });

            var charge = charges.Create(new StripeChargeCreateOptions
            {
                Amount = 500,
                Description = "Sample Charge",
                Currency = "usd",
                CustomerId = customer.Id
            });

            Console.WriteLine(charge.Id);
        }

    }
}

what I noticed is that if I enter and email of [email protected] without the "com" in the end, the code above gets executed, but it will say the email is invalid on Email = Request.Form["stripeEmail"].

so the question is does the money gets deducted when I get the token Request.Form["stripeToken"] or the money gets charged/deducted when I created a Charge via:

var charge = charges.Create(new StripeChargeCreateOptions
{
    Amount = 500,
    Description = "Sample Charge",
    Currency = "usd",
    CustomerId = customer.Id
});
