Stripe Checkout doesn't save the registrar and doesn't send confirmation emails

I just added stripe checkout payment. If I choose stripe in my registration form, I get my payment, but no confirmation emails are sent and the registrar is not registered. I use offline payment or Paypal payment also and then the person in registered and I get confirmation e-mails. What have I done wrong?

Added the webhook, and now it works

Yes. When you use Stripe Checkout, you need to setup webhook as described in readme.txt file

I'm glad you figured it out and have it works as expected now
