Dear friends!
Please welcome our Authorization with Sber ID add-on!
One-click sign-in and sign-up with Sber ID. Customers do not have to invent a password, fill in a registration form or type an address: the add-on creates the account from Sber ID data and links it to an existing account when the customer already has one.
Features
- A «Sign in with Sber ID» button on the login page, in the login pop-up and at the authorization step of checkout.
- Automatic customer creation: first name, last name, e-mail, phone and delivery address are taken from Sber ID.
- Linking to an existing account by e-mail or phone — confirmed with the account password, so no duplicate customers appear.
- Linking and unlinking Sber ID from the customer account and from the customer profile in the admin panel.
- Button settings: six sizes, dark and light themes, personalized variant.
- Logging of Sber API calls in the native CS-Cart event log (all operations or failures only).
How it looks

How it works
Step 1
The customer clicks the button and confirms the sign-in in the bank app or by phone number. Step 2
The store receives the customer’s name, e-mail, phone and delivery address from the service. Step 3
The account is created or linked to an existing one — the customer is signed in.
Configuration
All parameters live on the add-on settings page: Client ID, Client Secret, client certificate upload and its password, and the button appearance. No code or template edits are required.
Six button sizes — from compact to large and full-width.
Two themes: green and light.
A personalized variant showing the customer’s name if they are already signed in to the service.
Link management
The customer sees the link status in their account and can link or unlink Sber ID themselves.
The administrator sees the same status in the customer profile and can remove the link.
What your store gains
- Fewer abandoned carts: registration stops being a barrier before checkout.
- More complete profiles: contacts and address arrive on the very first sign-in.
- Fewer delivery errors: address and phone are filled in without customer typos.
- A cleaner customer database: linking by e-mail and phone prevents duplicates.
Compatibility
Authorization with Sber ID add-on version 1.0 is compatible with CS-Cart and Multi-Vendor versions 4.17.1 - 4.20.x.
