WordPress WooCommerce SSO Integration with Keycloak for User Sync

Single Sign-On fulfils the most basic requirement of authentication with a single set of credentials in any business environment, increasing the efficiency in maintaining user data. Here, we will explore one real-life case where users SSO in the Woocommerce WordPress site and a sync is required to create users in Keycloak (IDP). The WordPress SAML SSO Plugin enables secure authentication and provides Attribute and Role Mapping that allows syncing/mapping of user-profiles from the Keyclaok (IDP) to WooCommerce profile fields and also assigns roles based on the user's group.


You have a WordPress site to sell discount coupons for courses on an external LMS platform, and your users are stored in Keycloak.

  • Woocommerce is installed on the WordPress site for selling discount coupons
  • Keycloak is the Identity Provider i.e. users are stored in Keycloak
  • Users register on the Woocommerce site for purchasing discount coupons of LMS courses


  1. WooCommerce Single Sign-On (SSO): Single Sign-On in Woocommerce site for users so that users can use their Keycloak credentials to login into Woocommerce for purchasing discount coupons. If the user is already logged into the LMS platform, Woocommerce SSO would allow users to access the Woocommerce discount coupons without entering credentials again for authentication.
  2. WooCommerce User Sync to Keycloak: Sync users into Keycloak that register on the WooCommerce site during checkout. This allows the users to access the LMS platform using the same credentials.
