Billing that fits your stack

Add billing views to your URLconf. Django's CSRF protection works out of the box for billing forms, and you can exempt webhook endpoints with a decorator.

billing/views.py

from django.http import JsonResponse
from django.views.decorators.http import require_POST
from billing.commet_client import commet

@require_POST
def subscribe(request):
    data = json.loads(request.body)

    commet.customers.create(
        email=data["email"],
        id=data["customer_id"],
    )

    subscription = commet.subscriptions.create(
        customer_id=data["customer_id"],
        plan_code="pro",
    )

    return JsonResponse({"checkout_url": subscription.data["checkout_url"]})

from django.http import JsonResponse
from django.views.decorators.http import require_POST
from billing.commet_client import commet

@require_POST
def subscribe(request):
    data = json.loads(request.body)

    commet.customers.create(
        email=data["email"],
        id=data["customer_id"],
    )

    subscription = commet.subscriptions.create(
        customer_id=data["customer_id"],
        plan_code="pro",
    )

    return JsonResponse({"checkout_url": subscription.data["checkout_url"]})
