For purchases made through your links on Instagram and Facebook, the transaction will show on the affiliate platform the link came from, not inside Instagram or Facebook.
For TikTok Shop specifically:
If you don't manually add a TikTok Shop product link to the video in Scaled Creator, we direct the viewer back to your TikTok video. If they purchase from there, it will show up like a regular video sale in TikTok.
If you manually add the TikTok Shop product link, Scaled Creator sends the viewer directly to the TikTok product page. Those clicks and sales will show under Affiliate Link Performance in your TikTok analytics.
For Amazon links, clicks, orders, and commissions will show in your Amazon Associates reports.

Scaled Creator helps distribute your affiliate links, but the final sale and commission reporting is handled by TikTok or Amazon.
