Our attribution platform works best when we have access to data from all of the platforms you advertise in. Granting us access to your TikTok data requires your TikTok Ad Account ID, which you can find here:
It's 19 digits long (!). So on our Integrations page (which you can find in "Settings"), click "Connect" next to "TikTok" (under "Attribution"), enter the Ad Account ID, click "Continue", sign in if you need to (you'll need to be a member of the TikTok business you're trying to connect), when given the opportunity select "Confirm" to grant us access, and you'll see our success page.
