TikTok-related fees

[storemanager1]

I’m trying to understand the complete set of fees are to be paid for sales made on Tiktok. For example, if I sold $100 worth of product on TikTok, I believe TikTok charges an 8% referral fee and handles the payment processing too (say 3%). Besides these two, does Shopify charge any additional fees (commissions/variable fee etc.) for selling on TikTok. I believe there is a 1% transaction fee for the 51st to the 99th order (up to $99/month max), which goes to Shopify. But is that the complete set of fees: 8% referral fee + payment processing (3%) [both of these to TikTok] + 1% transaction fee [to Shopify]?

So does Shopify essentially earn only a transaction fee up to a $99/month, for me selling on TikTok?
