Creating a function after payment is successfully done

Shopware 6 (English)

I want to create some function that when payment transition is successfully done. Is there a method for that or how can i handle that transition ?
NOTE : I’m using Mollie plugin

Maybe Mollie has a Webhook, not sure about that.

Or create your own plugin, subscribe to the Event and execute your code.

Actually, i am trying to create my own plugin for this situation but the bad part is every method i’ve tried didn’t fix my problem yet.
All i’m asking is state_enter.order_transaction.state.paid is this one the correct method for to handle „paid“ statement ?

                ->addAssociation('paymentMethod'),
            $event->getContext()
        )->first();

        if (!$transaction instanceof OrderTransactionEntity) {
            return;
        }

        $order = $transaction->getOrder();
        if (!$order instanceof OrderEntity) {
            return;
        }

check the file vendor/shopware/core/Checkout/Order/OrderEvents.php here you can find all events which are triggered by shopware.

you could also create a custom flow event and configure it in flow builder
