Strange that the partner needs to be pay, with most payment gateways is the other way around. The developer works to bring more customers and a higher sales volume and the payment gateway in return does revenue sharing.

It might be worth it. In our case being listed on Stripe's website brought a non-negligible number of new customers.

For Stripe, it may be a way to filter out not serious applications.

Other payment gateways often need you more than you need them ;)
