We are new to Shopify partner apps.

I want a 10% fee on my marketplace sales channel when my customer purchases a shopify merchant product. How can I keep the percentage commission for orders that are made on my marketplace? Lets say the order amount is $100 and out of that our marketplace commission is $10 on our shopify marketplace partner app.

The app is free to use for Shopify merchants. We are using the checkout API (not Billing API) and Shopify has approved our Stripe connected account. Thanks in advance!

Any pointers on this at all? We are interested in doing this to.
