Offsite Payment App: Retrieve VAT Before Redirecting to Payment Gateway

[Miguel_Angel_Camacho]

Hi @Paige-Shopify

1. Yes. In Colombia, the payment gateway must receive the VAT (IVA) amount associated with the transaction. This is required to correctly process and report the payment according to local tax requirements.
2. We are currently gathering the relevant regulatory documentation and can provide it once available. However, this is a standard requirement for payment processing in Colombia, where the VAT amount must be included as part of the transaction information sent to the payment gateway.
3. This request is for our Shopify Offsite Payment App integration with Openpay Colombia.
4. The payment methods processed through our Openpay Colombia integration require the VAT amount before the customer is redirected to the payment gateway.
5. Our main challenge is that Shopify already calculates the taxes during checkout, but the VAT breakdown is not available in the Payment Session payload received by an Offsite Payment App.

I noticed more devs are having this issue:

Fetch order details in offsite payment extension

Hi, I am working on an Offsite payment extension. My payment gateway requires information about the purchased items (line name, line price). Thanks

Get taxes on offsite payment extension

Hey @Juan_Sebastian_Sanch , Typically that information is available through the Admin API, however, payment extensions are currently limited to only using the payment api’s. Can you share the use case for needing the tax details? I’d be happy to pass that feedback on to our payment teams to consider for future updates.
