Permission for the access token: To be able to generate an access token, an account assigned to the pixel must have full control permission, so make sure you or your client have that!
Do I need to be the Business Admin to use the app?
No, for the pixel to fire on the browser side, you only need to pass us the Pixel ID.
Chances are you also want to fire the pixel on the server side via Conversion API. In that case, you need to pass us the access token so Facebook knows we have the authority to send server events to your Pixels!
