PayPal.
For the 'business', enter the email
address of your Paypal account - this is effectively your PayPal user
ID.
Change the status from 'OFF' to 'ON' (for live
orders) or 'TEST' or 'FAKE' for testing. 'TEST' means that
transactions will be sent to PayPal's sandbox server. 'FAKE' means
that Kartris will skip the PayPal site and instead format a post back
itself to the callback page of Kartris. This is useful for testing
that the callback process works, triggers the appropriate emails and
so on without keep having to keep going through the PayPal payment
process.
If you have Kartris v2.9 or above, it
will automatically determine whether to post to the live or sandbox
Paypal server. If you have an earlier version of Kartris (or a Paypal
DLL in Kartris earlier than 1.1.0.0) you will need to change the URL
setting to the appropriate one for LIVE or test orders.
