When I try to use “Checkout Create payment link” for payment, I am currently testing in the sandbox environment and found that the parameters of Webhook “payment.updated” do not include “reference\_id” and “processing\_fee”. This is very important to me as I need to associate the order information in my system through “reference\_id” and also display the processing fee information to my users. Additionally, when using “Checkout Create payment link”, I have already set the information of “reference\_id” through “order.reference\_id”.

Is this only in the sandbox environment? Or does it also apply to the production environment?

Unfortunately, this is the expected behavior in sandbox with payment links. The payment link experience in sandbox is unfortunately incomplete. You can create a 0 dollar checkout to test the full experience in production. 🙂
