I'd like to build my shop as an Ember app and only use Shopify for the API and administration. However, there doesn't seem to be a way for customers to login via the API. I'm not talking about getting app access to the API, I'm talking about a customer logging into their specific customer account to view order history. Is this possible via the API? Thanks!
