            return Ok();
        }
        catch (StripeException ex)
        {
            //_logger.LogError(ex, $"StripWebhook: {ex.Message}");
            return BadRequest();
        }
        catch (Exception ex)
        {
            //_logger.LogError(ex, $"StripWebhook: {ex.Message}");
            return BadRequest();

Body not support

Which version of .NET are you using @vishal-parmar?

4.5.2 dot net version and 11.10 Stripe nuget version

Above code is for ASP.NET Core.
Please upgrade your Stripe SDK to its latest version, they have fixed many minor bugs in last few versions.

@a-patel Thank you sir.

How to get CustomerID from StripeEvents if ChargeSucceeded.

I have done

var customer = stripeEvent.Data.Object as Customer

but customer.Email and customer.ID get NULL

@vishal-parmar, if you are testing webhook in Test mode then you won't have customer details, it will only trigger the webhook for that event only.
