Double commissions with iDev

I’m seeing double commissions in iDev for affiliates, I believe it has something to do with Paypal as there are two emails and notifications that are sent, one that starts the transaction and then one that creates a recurring profile that does the monthly recurring billing. I’ve asked for help on iDev, but wanted to check here in case someone has seen this before and knows how to fix it!

Could you tell me how you set up the iDev integration? With the Tracking or the Notifications API, and which ones?

If you have the signup and payment notifications, for example, they’ll both happen on the first payment. The signup one is a paid registration. So on a paid registration three notifications happen: signup, payment and registration.
