I am trying to implement Braintree payments into a Magento 2.1.2 store.
I have followed these guides to set it up, and added in my merchant ID, public and private key: http://docs.magento.com/m2/ce/user_guide/payment/braintree.html
In checkout, when I click on the Braintree payment method radio button, I get the following JS error:
braintree-2.17.6.min.js:3 Uncaught Error: Braintree API Client Misconfigured: clientToken required.
Shouldn't the client Token be created OK if I've put in all the keys?
This is running in a local dev environment, is that the issue?
