Adding Braintree to our list of online payment gateways is not part of our short terms development plans. As you probably know, Nutcache was developed with one main objective in mind: to help reduce the financial burden and encourage growth of self-employed and start-up companies all around the world. Unfortunately, Braintree's international availability is limited to North America and a few countries in Europe. However, Nutcache already supports the following payment gateways: PayPal, Authorize.Net, 2Checkout and Stripe.
