Flow
When the customer chooses card at the payment step, a payment session opens and they are redirected to the PayTR screen. Once the payment is confirmed, the appointment is created automatically and the customer returns to the thank-you page.
Slot lock
Until payment completes, the selected time is briefly reserved (about 30 minutes) so no one else can take it. If the time runs out or the payment fails, the slot reopens.
If payment fails
If the card payment fails, the customer can retry with a different card or (if enabled) switch to bank transfer. For troubleshooting, see the Payment issues guide.
