Configure Azure B2C OAuth Single Sign-On (SSO) in Prestashop | Azure B2C SSO

Prestashop OAuth Client module allows you to perform secure Single Sign-On (SSO) into your Prestashop store using Azure B2C as OAuth provider. Configure Prestashop OAuth Client for user authentication which verifies the identity of a user attempting to gain access to Prestashop with Azure B2C Login. Prestashop OAuth Client Single Sign-On (SSO) module also configures custom providers and standard IDPs. It supports advanced Single Sign-On (SSO) features such as user profile Attribute mapping, Role mapping, etc. along with other Active Directory Services. Here we will go through a guide to set up Prestashop OAuth Client with Azure B2C login credentials. Adding Azure B2C OAuth Single Sign-On (SSO) to Prestashop lets your users quickly and securely log in to your Prestashop store with Azure B2C login without having to remember a username and password.

Pre-requisites: Download And Installation

You need to download and install the miniOrange OAuth Client plugin to set up Single Sign-On with your Prestashop Store.

Steps to configure Azure B2C OAuth Login with Prestashop

1. Setup Azure B2C as OAuth Provider

• Sign in to Azure portal.
• Go to Home and in the Azure services, select Azure AD B2C.


• Please make sure you are in the Azure AD B2C directory with an active subscription and if not, you can switch to the correct directory.



• In the Essentials tab, you will find the Azure B2C domain name, keep it handy, you will need it later for configuring the Azure B2C tenant name under Prestashop as an OAuth client.



• Now, click on App registrations and then click on the New registration option to create a new Azure b2c application.



• Configure the following options to create a new application.
  • Enter a name for your application under the Name text field.
  • In supported account types, select 3rd option ‘Accounts in any identity provider or organizational directory (for authenticating users with user flows)’.
  • In the Redirect URI section, select the Web application and enter the Callback URL from the miniOrange OAuth Client plugin (Configure OAuth tab) and save it under the Redirect URL textbox.
  • Click on the Register button to create your application.



• After successful application creation, you will be redirected to the newly created application’s overview page. If not, you can go to the app registrations and search the name of your application and you will find your application in the list.
• Copy your Application ID and keep it handy, you will need it later for configuring the Client ID under Prestashop as an OAuth Client plugin.



• Now, click on Certificates and secrets and then click on New client secret to generate a client secret. Enter a description and click on the Add button.



• Copy the secret value from the certificates & secrets page and keep it handy, you will need it later for configuring the Client Secret under Prestashop as an OAuth Client plugin.

• In the home page, go to the Users tab in the left corner.
• Click on New user on the Users page.



• Select Create Azure AD B2C user. Then, scroll down and click on Email from sign-in method and set your password and click Create to save the user details to perform test configuration.

• Go to App Registrations and click on Endpoints. Copy the Azure AD B2C OAuth 2.0 token endpoint and Azure AD B2C OAuth 2.0 authorization endpoint. These will be your OAuth token endpoint and OAuth Redirect callback.




You have successfully configured Azure AD B2C as OAuth Provider for achieving user authentication with Azure AD B2C Single Sign-On (SSO) login into your Prestashop Store.

2. Setup Prestashop as OAuth Client

• Go to the OAuth Client section in the module and enter the following details:

Azure B2C OAuth Endpoints and Scope:




OAuth Client ID	Enter the value copied from Azure Application in the previous steps
OAuth Client Secret	Enter the value copied from Azure Application in the previous steps
OAuth Scope	openid
OAuth Redirect callback	Enter the value copied from Endpoints in Azure B2C Application and replace with the policy name copied earlier
OAuth Token endpoint	Enter the value copied from Endpoints in Azure B2C Application and replace with the policy name copied earlier
OAuth user info endpoint	https://graph.microsoft.com/v1.0/me



• Click on Save to save the configuration.

3. Testing SSO
