Thanks Russ, Yes I guess getting the callback page to write to the database, and then the original request read and wait for that database value is a way to solve this. And yes we do pass a unique transaction reference to identify the value - its just a bit clunky compared to it all being in one request which is how our other PSP, 'datacash' (who I highly recommend BTW) handle things.
