Retrieving Stripe metadata and process it - django

Question

I am sending cart data from the cookies to Stripe and retrieving it, but I am unable to find a solution to process it correctly.
Please help!
I am learning Django and wanted to save the cart items of non-logged users into the cookies and send it to Stripe, as Metadata.
From there retrieve it and if the checkout is completed to process the order, but I am unsuccessful to process the data that is retrieved to be able to save the order.
Stripe Checkout Session:
#csrf_exempt
def create_checkout_session(request):
stripe.api_key = settings.STRIPE_SECRET_KEY
domain_url = 'http://localhost:8000/checkout/'
if request.user.is_authenticated:
customer = request.user.customer
else:
data = json.loads(request.body)
total = data['form']['total'].replace('.', '')
email = data['form']['email']
first_name = data['form']['first_name']
last_name = data['form']['last_name']
customer, created = Customer.objects.get_or_create(
email=email
)
customer.first_name = first_name
customer.last_name = last_name
customer.save()
cart_info = cart_details(request)
cart_items = cart_info['cart_items']
order = cart_info['order']
items = cart_info['items']
print(items)
if request.method == 'GET':
checkout_session = stripe.checkout.Session.create(
shipping_address_collection={
"allowed_countries":
["US", "CA", "NL", "GB"]
},
client_reference_id=request.user.id,
customer_email=request.user.email,
success_url=domain_url + 'success?session_id={CHECKOUT_SESSION_ID}',
cancel_url=domain_url + 'cancelled/',
payment_method_types=['card'],
mode='payment',
line_items=[
{
'name': 'Kenpachi Katana Store',
'quantity': 1,
'currency': 'usd',
'amount': int(order.get_cart_total*100),
}
]
)
return JsonResponse({'sessionId': checkout_session['id']})
else:
checkout_session = stripe.checkout.Session.create(
shipping_address_collection={
"allowed_countries":
["US", "CA", "NL"]
},
**metadata=[items]**,
client_reference_id=customer.id,
customer_email=email,
success_url=domain_url + 'success?session_id={CHECKOUT_SESSION_ID}',
cancel_url=domain_url + 'cancelled/',
payment_method_types=['card'],
mode='payment',
line_items=[
{
'name': 'Kenpachi Katana Store',
'quantity': 1,
'currency': 'usd',
'amount': total,
}
]
)
return JsonResponse({'sessionId': checkout_session['id']})
Terminal Output with the Cookie Cart variable:
print(type(items))
<class 'list'>
And:
[{'product':
`{'id': 1,
'name': 'Sasuke Katana',
'price': Decimal('270.00'),
'imageURL': '/media/1_ccbb983f-a35d-40f8-8efb-dc55db02ad8f_700x.webp'},
'quantity': 1,
'get_total': Decimal('270.00')},
`
{'product':
{'id': 3,
'name': 'Zoro Katana',
'price': Decimal('260.00'),
'imageURL': '/media/1_466b0afb-d483-4a32-b0bb-89388aeccaa4_700x.webp'},
'quantity': 1,
'get_total': Decimal('260.00')
}]
And it easy to loop through it
for item in items:
print(item)
Output:

After the the order is completed, I retrieve the Stripe Session to fulfill the order
#csrf_exempt
def stripe_webhook(request):
stripe.api_key = settings.STRIPE_SECRET_KEY
endpoint_secret = settings.STRIPE_ENDPOINT_SECRET
payload = request.body
sig_header = request.META['HTTP_STRIPE_SIGNATURE']
event = None
try:
event = stripe.Webhook.construct_event(
payload,
sig_header,
endpoint_secret
)
except ValueError as e:
return HttpResponse(status=400)
except stripe.error.SignatureVerificationError as e:
return HttpResponse(status=400)
if event['type'] == 'checkout.session.completed':
session = event['data']['object']
session = stripe.checkout.Session.retrieve(
event['data']['object']['id'],
expand=['line_items'],
)
stripe_metadata = session['metadata'].setdefault('0')
print(stripe_metadata)
print(type(stripe_metadata))
# Fulfill the purchase...
# TODO: drill down on the metadata from stripe
transaction_id = datetime.datetime.now().timestamp()
total = session['amount_total']
customer_id = session['client_reference_id']
customer = Customer.objects.get(pk=customer_id)
order, created = Order.objects.get_or_create(
customer=customer,
complete=False
)
order.transaction_id = transaction_id
if (total / 100) == int(order.get_cart_total):
order.complete = True
ShippingAddress.objects.create(
customer=customer,
order=order,
address=session['shipping']['address']['line1'],
city=session['shipping']['address']['city'],
state=session['shipping']['address']['state'],
zipcode=session['shipping']['address']['postal_code'],
country=session['shipping']['address']['country'],
)
order.save()
print('Order was added to the database')
return HttpResponse(status=200)
Terminal Output:

What would be the best option to retrieve it in the same format, to be able to iterate through the products of the cart.
Any help would be deeply appreciated.

Thank you!

Maybe you can try
stripe_metadata = json.loads(str(stripe_metadata))
to convert string to JSON format
