Hello @bleak cloud can you clarify your question a bit? Are you a developer? Which product are you using?
bleak cloud
yes
I want to add the VAT using the APIs
using invoicing

Okay so you are calculating the tax yourself or you want Stripe to do it for you?
If you want us to do it via our Stripe Tax product you should read https://stripe.com/docs/tax/invoicing
If you want to do it yourself, you'll want to use our TaxRate API and add one to your Invoice or line items: https://stripe.com/docs/invoicing/taxes/tax-rates

ok thank you
since I have invoice items with negative amount, how should I go about it?

I'm not really sure I follow what you mean unfortunately. Did you read the docs I mentioned? It works the same way whether the amount is negative or not
