Our attribution platform works best when we have access to data from all of the platforms you advertise in. Granting us access to your Pinterest data requires your Pinterest Ad Account ID, which you can find here:
It's twelve digits long; note that this is not the longer number under your name, it's the number under your account name. On our Integrations page (which you can find in "Settings"), click "Connect" next to "Pinterest" (under "Attribution"), enter the Ad Account ID, click "Continue", sign in if you need to (you'll need to be a member of the Pinterest business you're trying to connect), when given the opportunity select "Give access" to grant us access, and you'll see our success page.
