Unable to update database in Stripe webhook

I have a mongodb database tracking if a user has paid through stripe. Once a user pays, I would like to change the database from False to True. However, even though my webhook seems to be working on the Stripe dashboard, the database isn’t updating. Additionally, if I add a print statement it doesn’t print anything.

I am using the test mode on stripe and using Heroku domain for my endpoint. My stripe dashboard indicates that the invoice.payment_succeeded is working normally and is marked as – ‘succeeded’

Here’s my webhook code:

@main_bp.route("/hooks", methods=["POST"])
def stripe_webhook():
    try:
        payload = request.get_data(as_text=True)
        sig_header = request.headers.get("Stripe-Signature")

        try:
            event = stripe.Webhook.construct_event(
                payload, sig_header, endpoint_secret
            )
            data = event['data']

        except ValueError as e:
            # Invalid payload
            return "Invalid payload", 400
        except stripe.error.SignatureVerificationError as e:
            # Invalid signature
            return "Invalid signature", 400

        # Handle the checkout.session.completed event
        if event['type'] == 'invoice.paid':
            # THIS PART IS NOT WORKING ↓
            print("Payment was successful.")
            mycol_users_consumer.find_one_and_update({"consumer_email": current_user.email}, 
                {"$set": {"user_paid": "True"}})
        elif event['type'] == 'invoice.payment_failed':
            print("Payment not successful.")
            print(data)
        return "Success", 200
    except Exception as e:
        print(e)

Heroku Logs indicate a 200 on the webook:

Answer

Your question talks about seeing invoice.payment_succeeded events in the dashboard, but your code is handling the invoice.paid event type. If the mismatch was unintentional, your code needs to be updated to handle the invoice.payment_succeeded event type.
