Интеграция Razorpay Django с URL обратного вызова (CSRF-токен отсутствует или неверен.)

Я пытаюсь создать представление на основе классов с помощью Razor Pay, все работает идеально. Но когда я отправляю данные в то же представление, оно выдает ошибку Forbidden (CSRF token missing or incorrect.): /buy-coin.

У меня два вопроса

1. How we can exempt CSRF Token for post method
2. In Razorpay Javascript Code, can we add csrf token in callback url.

View.py

class BuyCoinPageView(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
        client = razorpay.Client(auth=("scretKey", "secretKey"))
        data = { "amount": 10000, "currency": "INR", "receipt": "order_rcptid_11" }
        payment = client.order.create(data=data)
        print('Razor Pay - ', payment['id'])
        return render(request, "pricing-page.html", {'payment': payment})
    
    def post(self, request, *args, **kwargs):
        data = request.POST
        print(data)
        return render(request, "pricing-page.html")
