After switching our (not yet working) application from v1 to v2 I managed to create a first test order. The response was basically ok (finding and quoting the correct shipping and billing address), but had the following error:
ERR-TICOM-ORDER-API-0009
Invalid Apruve payment Id
Check your Apruve Account information in checkout profile and resubmit your request.
Now the customer says that he c/p his apruve id from his old (v1) account to the new (v2) one. Is it necessary to create a new apruve id as well to use the new API version?
