Payment gateway reference Id

[stealth-dev]

Once an order is placed by the user, is there are a way to get any transaction id/reference number from the payment gateway on the order.

We want to be able to link the order data on shopify with the reports from the payment gateway we are using.

We also want this information to be available in the "create order" webhook. Looked at the Order resource documentation, however could not find any field that provides a transaction identifier from the payment gateway.

Is there a way to get this identifier?

I have the very same issue right now. 

Tried to look at the Transaction ressource that gives more details about a payment, but still no luck 😞
