The Fanvue API lets your app work with a creator’s account: chats, posts, media, subscribers, insights and payments. Every integration starts as an app you create in the Developer Area at https://www.fanvue.com/dev, and you need a Fanvue creator or agency admin account to make one. Fanvue has no API keys. A creator or agency admin authorises your app through OAuth 2.0 and you call the API with the access token you receive; see Authentication.
