Django Tastypie interaction with the API through PostMan REST client

I was trying to create a Login module in tastypie Api, when testing it with Postman REST client getting error. 

Method : POST
format : application/json
content type : json

raw data:  {
             'type': 'login',
             'username': 'username',
             'password': 'password'
            }



def login(self, request, **kwargs):
    self.method_check(request, allowed=['post'])

    data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json'))

    username = data.get('username', '')
    password = data.get('password', '')

    user = authenticate(username=username, password=password)
    if user:
        if user.is_active:
            login(request, user)
            return self.create_response(request, {
                'success': True
            })
        else:
            return self.create_response(request, {
                'success': False,
                'reason': 'disabled',
                }, HttpForbidden )
    else:
        return self.create_response(request, {
            'success': False,
            'reason': 'incorrect',
            }, HttpUnauthorized )

replace single quotes with double quotes ex:

 {"type":"login","username":"username", "password":"password" }
