[AlphaCommerceHub] What is the recommended way to detect the chosen payment option from a `SuccessURL` response?

I have included below is a list of SuccessURL responses for different payment options.

The chosen payment option can be detected with some heuristics / guessing (for example, a bank card payment’s SuccessURL response could contain "ProviderName": "westpac", and a PayPal payment’s SuccessURL response does not contain a JSON at all), but it could be erroneous or unstable.

So what is the recommended way to detect the chosen payment option from a SuccessURL response?

Why do not just include the chosen payment option to a SuccessURL response?

I have got a response from AlphaCommerceHub:

The field Method is supposed to be in the response which would distinguish the chosen payment method.
