Can you help with iyzico integration on the website using php?

[BrianBOSS]

Hello friends, my issue is about the iyzico integration on the website. We have obtained the theme, international API, and key. Payments are going through, but it does not show that orders have been received and orders are not appearing in the management panel. However, everything works correctly when a purchase is made through a bank transfer. Can anyone who understands iyzico integration please help? I would appreciate it.
