How can I pay my app developer a commission?

Hey, guys.

I just installed Goaffpro. It’s a dynamite tool for referrals, and the support has been stellar–with at least one badly needed feature added literally overnight!

At the moment, there isn’t an API he can use to get a percentage of a referral sale. I’d like very much to do that, if I could. It would reward him for a job well done, and let me unlock advanced features at a price I can afford while sales are just beginning, and at a rate that will let me reward him handsomely when sales take off!

The tricky bit is that Shopify needs to manage the process. To keep it manageable, the rate could be fixed (1%, say, or .5%), and give me the option of enabling or disabling it to access the advanced features.

Where do I send a feature request like that?

I believe you could do this with the Billing API:

You could set up a commission structure with the usage charge:

Talked with my app developer. His response:

Shopify charges a 20% fee on their billing API to developers.
It could work as an Interim measure, but would eat up all the
margins in the long run.

Too bad! A more practical fee structure would be a win-win-win for me, the
app developer, and Shopify!
