django-rest-auth with django-allauth not what I was expecting

[Daniel Grace]

I am trying to write a Django / REST API back end with Facebook authentication, for use with a phone app front end. I installed and configured both django-rest-auth and django-allauth.  When testing I can log into Facebook and authorise my app to access my Facebook account, OK.  But then I am faced with a HTML form for specifying a Django user name, I was expecting a REST API request for this information.  Is there a reasonable way to configure these packages so that all the communications are via REST? (Am I misunderstanding something?)
