Steps to integrate social login into a Shopify headless Hydrogen store using the Shopify SSO app
Integrating social login into a Shopify headless store built with Hydrogen requires a slightly different approach than a traditional Shopify store. With the Shopify SSO app, you can handle authentication outside the default Shopify login flow while still using the Customer Account API for user management.
Here’s how to set it up:
Install and Configure the Shopify SSO App
- Add the Shopify SSO app from the Shopify App Store.
- Select the protocol supported by your social login provider and choose your desired providers, like Google, Facebook, or LinkedIn.
Shopify Plus with Multipass:
- If your store is on Shopify Plus, the Shopify SSO app supports Multipass to generate secure login tokens after a user logs in via social login.
Set Up Social Providers
- In each provider’s developer console, configure client IDs, client secrets, and the redirect URLs generated by the Shopify SSO app.
- These URLs handle the OAuth flow and route users back to your Hydrogen store.
Integrate with Your Hydrogen Frontend
- Add “Sign in with Google, Facebook, etc.” buttons in your Hydrogen storefront.
- Link these buttons to the SSO login endpoints provided by the Shopify SSO app.
Authentication Flow Handling
- The app manages the complete OAuth process, which includes redirecting to the social provider, retrieving profile details, and verifying the user.
Customer Account Creation and Mapping
- If a new user signs in via social login, the SSO app automatically creates a matching customer account.
- Existing customers are mapped based on their social account email.
Token Management in Hydrogen
- The Shopify SSO app returns a customer access token to your Hydrogen app.
- Store this token securely, either in local storage or cookies, to keep the user logged in for future API calls.
Testing and Optimization
- Test all login flows, like Google and Facebook, to ensure smooth redirection, token handling, and session persistence.
Why Use Shopify SSO for This
The Shopify SSO app makes it easier than building your own backend, managing OAuth flows manually, and integrating with the Customer Account API. It works for both standard Shopify stores and Shopify Plus stores, offering built-in Multipass support and ready-made integrations with popular IdPs and social providers.
