You can try the Affiliate Marketing app from Secomapp, which is extremely easy to set up, it also supports integrating with Bold Subscription and provide an accurate tracking process. The tracking options could be via the affiliate link, coupon code, customer email or SKU.
The app also works with Shopify buy button, you just need to add the third-party tracking code on the WordPress website and the app will track the click.
