You can connect a Creator account by using the Impact.com integration in Affluent
Refer to the following instructions for connecting an Impact.com account here: https://www.affluent.io/integrations-hub/impact-advertiser-api/
Once you've clicked connect, you'll see a list of campaigns to connect.
For a Brand, there might be two campaign options to select from, e.g.
There should be some sort of indication of the program type, e.g. Affiliate or Creator, in the parentheses following the Brand Name when you're connecting an account. This will mirror the program names that you see in the Impact.com dashboard.
Go ahead and select the Creator campaign, and then hit "Connect Account". You can also select both campaigns if you'd like Affluent to pull data for both of these Impact.com programs - you can always filter your data in custom reports by using the "Campaign" filter.
