The issue you're encountering is because the Price field should be a reference to a predefined price object in Stripe, not a direct amount. If you want to specify an amount directly, you need to use the Amount and Currency fields within PriceData . var options = new Stripe.Checkout.SessionCreateOptions { PaymentMethodTypes = new List { "card" }, LineItems = new List { new Stripe.Checkout.SessionLineItemOptions { PriceData = new Stripe.Checkout.SessionLineItemPriceDataOptions { UnitAmount = 200, // Amount in cents (2.00 USD) Currency = "usd", ProductData = new Stripe.Checkout.SessionLineItemPriceDataProductDataOptions { Name = "Your Product Name", }, }, Quantity = 2, }, }, Mode = "payment", SuccessUrl = "https://yourdomain.com/success", CancelUrl = "https://yourdomain.com/cancel", }; var service = new Stripe.Checkout.SessionService(); Stripe.Checkout.Session session = service.Create(options); Please refer the stripe document https://docs.stripe.com/api https://github.com/stripe/stripe-dotnet https://docs.stripe.com/get-started/development-environment?lang=dotnet
