The Influencer campaign type is built for larger creators on negotiated terms. Two practical differences from organic UGC campaigns:
Delivery is by URL: influencers paste their post links into the app rather than linking their whole account for auto-detection.
Every payment structure is available: CPM, flat, per post, per view, spend share, rev share, or mixed (flat base plus CPM).
Negotiation happens through per-creator overrides: when you invite an influencer you can set a custom rate on top of the campaign's tiers: plus whatever you agree in chat before partnering.
