As a simplest possible form you can pass jwt as s string:

           }
           token = {'token': jwt.encode(payload, self.SECRET)}
           return HttpResponse(
             json.dumps(token),
             content_type="application/json"
           )
       else:
           return HttpResponse(
             json.dumps({'Error': "Invalid credentials"}),
             status=400,
             content_type="application/json"
           )

I have written a login api which which should return the token if user is valid and then would save the same on client side.

But my api is getting this following error..

TypeError at /login/

 is not JSON serializable

I think that datetime.utcnow() returns a datetime object, not a string, and I don't think it can be serialized directly. You should try converting that object to a string in the right format. As a test, substitute a static string containing a date and time in whatever format you need. I'm not in front of an interpreter so I can't test, but this seems to back up my theory:

Forgot to mention, you may also want to take a look at the built-in JSON encoder, which handles datetime objects:

According to pyjwt docs it can be either datetime object or number (unix epoch)
