Clarify getTransactionId vs getTransactionReference

[eileenmcnaughton]

I'm just wanting to check I'm right before I try to change my gateway to follow this - I believe that

getTransactionId
should return the ID generated by the client site (ie. the commerce site or other site that uses a payment gateway service).

getTransactionRef
should return a gateway generated unique ID. (e.g paypal reference)

I'm focussing on completePurchaseRequest at the moment but I think this should be the standard pattern are you able to confirm?

Yes, getTransactionReference() is the ID generated by the gateway. The transaction ID is generated, as you say, by the merchant site/commerce site/your site.

I think this answer has been open long enough without any arguments against it :-)
