Shopify API Customer Login, Logout and Signup

[Aljazari]

Hello!, i am develoing an API for mobile phone application such as Android and IOS for my customer!

The application is nearly complated. However I do not see any documantations about Customer Login & sign up etc.

I need to confirm clients of the store owner can login via mobile phone application.

So please tell me what i can do for this steps? Should i stop the development ? or continue ?
