I try to use Braintree Card Payment extension from Magento 2, but I can't find a solution. If I use card payment from magento web theme, it works fine, but if I make endpoint requests from Postman I receive the following error message:
Transaction has been declined. Please try again later.
I use magento 2 endpoinds:
/rest/V1/carts/mine/shipping-information and /rest/V1/carts/mine/payment-information
I read that if you want to integrate braintree card payment for native mobile app (frontend), you need to create a custom module programatically on backend.
Someone else has done this and can help me with an implementation or some steps to follow?
