Is there a way for the client to know if the oauth2 flow resulted in a signup or a signin?

Good question. Yes, there is a way. During auth, social-core is adding 'is_new' bool attribute to the user instance. So you can add it to your serializer.

Let's say you are using session to authenticate the user. Then you can override the serializer like this:

1. Define your user serializer, add optional is_new field

   
   from rest_framework import serializers
   from django.contrib.auth import get_user_model

class MyUserSerializer(serializers.ModelSerializer): is_new = serializers.BooleanField(required=False, read_only=True, default=False)

class Meta:
    model = get_user_model()
    fields = '__all__'  # or whatever fields you need

2. Specify it in the view
```python
from rest_social_auth.views import SocialSessionAuthView
from .serializers import MyUserSerializer

class MySocialView(SocialSessionAuthView):
    serializer_class = MyUserSerializer

3. Override the url:

   urlpatterns = [
   re_path(
       r'^api/login/social/session/(?:(?P<provider>[a-zA-Z0-9_-]+)/?)?$',
       views.MySocialView.as_view(),
       name='social_login',
   ),
   ...
   ]

   After that you should seen either {"is_new": False, ...} in response - it means signin OR {"is_new": True, ...} - it means signup.

For other ways to authenticate the user (Token, JWT, etc) it can be done in similar way. Worth adding to the base functionality of current package btw.
