Hi,
I have looked around and I was not able to find facebook login feature, so I wonder if that will be possible to be done via an app? My idea is, basically, manually register the user coming from the facebook login using the shopify api and make him login to the site. Step by step it can be described as this:
- Create a facebook app for your domain and enable facebook login.
- Put the facebook login button to your theme.
- User clicks on the button, and facebook popup appears and user logs in.
- Popup redirects to my app in my own domain name, it takes the fb user token.
- By using the shopify api, it fetches the users and matches if there is user matching with that facebook id.
- If there isn't such a user, it creates a new user with email and some custom password credentials.
- (Then it makes a post request to login page of my myshopify.com with that credentials)
- User is logged in.
Theoretically having a cross matching table in another app that handles the matching logic, it might be done. What I'm not sure about is how I can make the user logged in to my store. The 7th step is the one which I'm not sure. Maybe there is a flag in users model or there is a session model or something like that I can say that user with this cookie is logged in as this user. But I'm not sure, if it's possible. The only workaround that comes to my mind is that I store the password I assigned to the user and I make a post request to the login page of the myshopify store.
There are some tricky parts but other than that it might seems like a possible scenario. With the same method twitter and other oauth systems might be integrated too.
Of course if there is an ongoing facebook login feature on the shopify, it's meaningless to speculate on this.
What do you think? Is it possible?
