Protx and Pre-Authorisation

[Guest]

Hello, I'm testing Protx at the moment and kept getting the error message:

 

Your transaciton could not be registered. Some of the information you passed is not compatible with your account. Check your vendor name, currency and transaction type.

 

I set "Use Pre-Authorisation for all transactions?" to false in my Admin panel and it now works.

 

My concern is that it isn't a good idea to set pre-auth to false. Does anyone have advice on this please?

 

Thanks.
