Stripe error

The store is in Grenada, West Indies (country code = GD) and our currency is Eastern Caribbean Dollar (Currency Code = XCD). So these settings have been added to WordPress/WooCommerce and all prices on the store are shown in XCD (aka ECD/EC$).

However, Stripe does not accept XCD. So when we send an order through Stripe we’re getting the Javascript error message about the country GD not being unsupported.This is the error:

Uncaught IntegrationError: Invalid value for paymentRequest(): country should be one of the following strings: AE, AT, AU, BE, BG, BR, CA, CH, CI, CR, CY, CZ, DE, DK, DO, EE, ES, FI, FR, GB, GR, GT, HK, HU, ID, IE, IN, IT, JP, LT, LU, LV, MT, MX, MY, NL, NO, NZ, PE, PH, PL, PT, RO, SE, SG, SI, SK, SN, TH, TT, US, UY. You specified: GD.

So, this is what I need to happen once the user hits the Checkout button when paying by Stripe):

-Convert the cart XCD value to USD by dividing by 2.67.

-Convert the paymentRequest country from GD to US.

And then send these to Stripe instead.

So for example, the cart value is EC$100.00 and the customer checks out using Stripe payment. At the moment, WooCommerce automatically sends to Stripe: country = GD and amount = 100.00. Instead we need country = US and amount = 37.46 to be sent to Stripe. But the customer always sees EC$ on the front-end. The customer never sees US$ on the front-end.

How can I:

1. Fix conversion rate from XCD to USD by dividing 2.67

2. Use USD on sending to Stripe.
