Hi,@Thibaut Fabrice. Welcome to Microsoft Q&A.

Correct the name below:

First

public double O5rderTotal { get; set; }

To

public double OrderTotal { get; set; }

Second

In the Mango_Order database, the O5rderTotal of dbo.OrderHeaders should also be changed to OrderTotal.

Third

config.CreateMap<OrderDetailsDto, OrderDetailsDto>().ReverseMap();

To

config.CreateMap<OrderDetails, OrderDetailsDto>().ReverseMap();

Fourth

StripeRequestDto  stripeResponseResult = JsonConvert.DeserializeObject<StripeRequestDto>
                    (Convert.ToString(response.Result));

To

StripeRequestDto  stripeResponseResult = JsonConvert.DeserializeObject<StripeRequestDto>
    (Convert.ToString(stripeResponse.Result));

Use the correct SecretKey

First

In my test, the SecretKey in your project seems to be unavailable. I used the SecretKey on the official website for testing.

"SecretKey": "sk_test_tR3PYbcVNZZ796tH88S4VQ2u"

You could use the above SecretKey for testing. It is better to get your own SecretKey from the official website.

Hi,@Thibaut Fabrice.

Fixed the bug that 13.99 becomes 14

Adjust the data type of the following locations.

First

public double Price { get; set; }

Second

public double Price { get; set; }

Fix discount coupon not working

First

If you are unable to use the discount coupon here.

You could regenerate a token and assign a value using the previous method

Second

The discount coupon for the generated order cannot be used. You could add code below the CreateStripeSession method to fix it.

//Create and add coupons
if (!string.IsNullOrEmpty(stripeRequestDto.OrderHeader.CouponCode))
{
    options.Discounts = new List<SessionDiscountOptions>();
    var couponService = new CouponService();
    var coupon = couponService.Create(new CouponCreateOptions
    {
        // Set how much to reduce (in cents, so multiply by 100)
        AmountOff = (long)(stripeRequestDto.OrderHeader.Discount * 100),
        // Setting the currency
        Currency = "usd",
        // Set discount validity period
        Duration = "once"
    });
    var sessionDiscount = new SessionDiscountOptions()
    {
        Coupon = coupon.Id,
    };
    options.Discounts.Add(sessionDiscount);
}

Operation Results

Hi,@Thibaut Fabrice.

I tested your latest project and it worked. You could try restarting it. If it still doesn't work, you could set a breakpoint at the position shown below and debug step by step to find the real cause of the error.

Hi,@Thibaut Fabrice.

Could you breakpoint at the above screenshot and run the project step by step to understand why stripeResponseResult is null.

Hi,@Thibaut Fabrice.

You could click here to set breakpoints.

Then run the project. After clicking Place Order, the program will enter the breakpoint position.

This is the case of successful entry.

Running the code line by line by clicking on the single-step debugger should trigger the actual error message.

Could you provide a screenshot of the error message here?

Hi,@Thibaut Fabrice.

You could add the following code to specify the name of the discount coupon. Screenshot 2024-11-20 011000

var coupon = couponService.Create(new CouponCreateOptions
{
    // Set the name of the discount coupon
    Name = stripeRequestDto.OrderHeader.CouponCode,
    // Set how much to reduce (in cents, so multiply by 100)
    AmountOff = (long)(stripeRequestDto.OrderHeader.Discount * 100),
    // Setting the currency
    Currency = "usd",
    // Set discount validity period
    Duration = "once"
});
