Sorry, I'm confused about why you would want this. 'Pending' is the status that's given to a commission when 1) the referrer is part of a partner program where the 2) product is commissionable and 3) we've tracked the referrer's link as the source of the sale. It's 'pending' because you still have to decide if you want to pay it or not.
It's up to you whether you show your users their pending commissions (if you're using Dynamic CMS for your partner center rather than the old wordpress thing).
I'm unclear why you would want us to add another step to the process here. Also, I'm unclear on the part where you say 'they never sent the customer their unique link' which can't be true... we aren't making up who the referrer is, it's tracked. I'm also unclear why you would not want to pay a commission to a referrer who made a referral for a product that you designated is commissionable?
Help me understand this?
