currency settings

Hi.

Braintree API does not support setting currency manually via API requests. Currency depends on your Merchant account. So if you have Merchant account that has GBP as default currency, you can specify its ID in plugin settings and all the transactions would be processed as GBP.

For Sandbox mode, you can create new Merchant with your currency using this guide: https://articles.braintreepayments.com/get-started/try-it-out#testing-currencies

For Production mode, you’d have to contact Braintree support to get this sorted: https://help.braintreepayments.com/
