Custom Payment Extension

[emil_kostadinov]

Thanks again! Got everything working... Now I want to catch the case when the order status is changed from the admin panel. Are there any good examples I can look into? Also, is it possible to display the payment URL somewhere on the order page?

Hello @emil_kostadinov

Why do you need to change order status from admin?

Magento 2 itself will do that.

When you generate invoice it will go processing, and after creating the shipment, it will complete order.

Do you want to any other customization for that?

If it will help you then mark as solution

The main case is when the order is canceled. The system has to cancel the external payment invoice - just want to create a simple handler that will send an API request to the payment service to cancel the invoice.

Hello,

I think it should be on credit memo generation, not when canceling the order.

Please check Magento 2 provide function refund to do that when you generate credit memo.

Hope it will clear your question.

If it will work then mark as solution.

What I did was to register a new observer on the order_cancel_after event. And now it cancels and the external payment. Another thing that I want to catch is when the invoice is set to On Hold. Searched for some other events like order_status_onhold but I couldn't find such. How can I execute a function when the order status is changed?
