hello, are you a developer integrating Stripe with code?

round moon Nov 29, 2021, 6:13 PM

#

yeah I am

#

am I in the right channel?

crude dragon Nov 29, 2021, 6:14 PM

#

yes this is a developer channel

round moon Nov 29, 2021, 6:15 PM

#

yeah so I am using the .NET stripe.net package

#

and I have an invoice and some lineitems added to it

crude dragon Nov 29, 2021, 6:15 PM

#

you update the Invoice to apply a Discount or Coupon https://stripe.com/docs/api/invoices/update#update_invoice-discounts

or apply a negative Invoice Line Item

#

Oh Ok thanks I can just add them as a line item but with a negative unit amount?

#

can I add discounts in as an InvoiceCreate Options?

#

Or can I add a negative invoice line item?

#

like an item with a negative price?

crude dragon Nov 29, 2021, 6:22 PM

#

you need to create an InvoiceItem and add it to that Invoice

round moon Nov 29, 2021, 6:23 PM

#

ok and the invoicitems price can be negative?

#

will that make it a discount?

crude dragon Nov 29, 2021, 6:24 PM

#

yes

round moon Nov 29, 2021, 6:26 PM

#

amazing thank you

#

one more thing

#

I want to use Stripe Tax

#

when I create my invoice how do i enable automatic tax?

#

Is there anything I have to do for the customer when I create it to enable automatic tax ? All I'm doing right now is creating a customer with an address

crude dragon Nov 29, 2021, 6:28 PM

#

round moon Nov 29, 2021, 6:29 PM

#

Quick question - have you read this doc yet https://stripe.com/docs/tax/invoicing ?

Automatically collect tax on invoices

Learn how to automatically calculate tax on your invoices.

round moon Nov 29, 2021, 6:46 PM

#

I have yes

light pier Nov 29, 2021, 6:46 PM

#

At the bottom it specifies how you would create an invoice and enable automatic tax

#

Basically, you just want to set automatic_tax[enabled]: true

round moon Nov 29, 2021, 6:47 PM

#

yeah I see that It just tells me how to do it with curl

#

I dont know how to do it with .NET

#

stripe.net package

#

Like I understand there is an AutomaticTax property on the invoice but I dont know how to set it

light pier Nov 29, 2021, 6:50 PM

#

Just to check - which version of the Stripe dotnet library are you using?

round moon Nov 29, 2021, 6:50 PM

#

39.80.0

light pier Nov 29, 2021, 6:53 PM

#

Then you'd just do soethign like this:

var options = new InvoiceCreateOptions
{
  Customer = "cus_XXX",
  AutomaticTax = new InvoiceAutomaticTaxOptions 
  {
    Enabled = true,
  },
};
var service = new InvoiceService();
service.Create(options);

round moon Nov 29, 2021, 7:10 PM

#

perfect thanks

#

when I submit the invoice

#

what can I do to check if it has been paid

#

this is what I'm doing right now

#


            if (res.Status != "paid")
            {
                return new Result<string>("PaymentFailed", "Your payment was not processed. Please enter a new card.");
            }```

light pier Nov 29, 2021, 7:17 PM

#

Yeah that should work if you're using the API to manually attempt payment on an Invoice

round moon Nov 29, 2021, 7:17 PM

#

yes I am

#

perfect thanks

round moon Nov 29, 2021, 7:49 PM

#

will the output contain the amount of tax

#

that was charged automatically

light pier Nov 29, 2021, 7:52 PM

#

Yes, it should be - let me check where it should be reflected

#

You should be able to see the total tax applied to the invoice at tax (see https://stripe.com/docs/api/invoices/object#invoice_object-tax)
