You can monetize products sold with Rye by marking up prices with a margin. This works for both the Sell Anything API and the Sync API. You can even double dip and combine markups with commissions in cases where you are using the Sync API. For example, if a pair of headphones costs $100 to fulfill, you can charge the user $120 and keep the difference to earn a profit of $20. When you place orders, you can mark up the Rye-quoted price before you charge the shopper with your own payment processor. Because the submitCart mutation only debits your Developer Account for the Rye-quoted price, you keep the difference with no reconciliation process or payout period. The margin can be set as a % of each item or a dollar amount per item. Margins set through the console will be paid out monthly directly to the developer.
