Asynchronous Payments

[Andy Malakov]

From what I can interpret, the assignment does not imply that payment transaction happens synchronously. Strictly speaking, all we know is that e-mail is sent after payment is authorized.

I've seen many large web sites performing credit card authorization later on, [after order submission].

Also, TransMaster call may take up to ? seconds (not counting time to transmit request and re-establish HTTPS connection, if dropped).

Any thoughts?

Andy,

I agree with you - it seems to be an asynchronous process.

as long as you document your assumptions you can go either way.

[Samuel Pessorrusso]

Just document your assumption. There were people who made it asynchronously and other made it synchronously.

Best regards

Thanks everybody.

Asynchronous payments may produce interesting situation when Itinerary is partially paid. For example, after "Change Itinerary" usecase updated segment may require additional payment that fails to complete due to something like credit card cancellation.
