Is it possible to add an entry action to the payment status Paid in state transition system?

We use the Adyen plugin and we want to execute integration code when a payment gets Paid.

Litium version: 7.02

No, it is not possible to add entry and exist actions for the payment states.

What you can do is to add a related state so when the state is changed for the payment you will move the order into next state that can have entry/exit actions.

Ok, is this the recommended way to handle server-to-server background calls from PSPs?

If we for example get at notification from Adyen that a payment is successfully captured.

Yes, it’s the recommended method.
