I have a task to integrate facebook marketing api with my web application. The ultimate aim of my web application is provide a capability for my clients to manage ads without login in facebook. So, I'm asking a question: is it possible to create the only one account for all my clients and manage ads by this account? And if I can, does it right way to use fb marketing api?
Anyway, i would appreciate if someone could give me advice about which approach i should use in my case to manage ads without any client-side authorization.
Yes, you can create ad accounts and run ads on Facebook for any number of clients for nearly any purpose* and not require them to log into Facebook. You can create ad campaigns and creative elements (graphics and links relevant to the client's products) using the Facebook Marketing API in your own ad accounts.
If you haven't seen it already, review the Facebook Marketing API getting started documentation and videos https://developers.facebook.com/docs/marketing-apis
*You're still held to FB terms of service so be sure to review requirements for allowed ad content.
