My URL for iDevAffilliate is: http://[MYDOMAIN]/idevaffiliate/admin/index.php
Should I use this complete URL as the path to the standalone version?
If you have your affiliate system on yoursite.com/idevaffiliate/ you just need to use
idevaffiliate.
There is a default entry for iDev orderid (order_id) and iDev order amount (order_subtotal), should these be changed?
No, you should leave those values as they are.
Best regards,
