Multi-Currency Percentage Promotions
You can configure the promotion to target all enabled transactional currencies when creating a promotion. The promotion will run regardless of what currency the shopper selects as transactional currency within the cart and checkout.
Multi-currency promotions intentionally only support percentage-based discounts (not amount-based discounts). You will not be able to create an amount-based promotion in multiple currencies. This choice prevents discounting based on fluctuating currency rates as some currencies have broader foreign exchange rates than others (for example, a 10 USD discount is substantially different from 10 JPY).
The following is an example of a coupon promotion offered to all international customers worldwide in their local transactional currency. The WELCOME10 coupon applies a 10% discount off the order, and you can digitally distribute the coupon through social media channels (e.g., Instagram, Facebook, TikTok) or email marketing. Use the Create a promotion endpoint followed by the Create a coupon code endpoint.
