Authorization with Sber ID: CS-Cart add-on from Cart-Power
Sign In with Sber ID

Sign In with Sber ID — no registration form

The “Sign in with Sber ID” button joins the sign-in page, the sign-in pop-up, the registration page and checkout. The customer confirms the sign-in in the bank app, and the store receives a ready profile: name, e-mail, phone number and delivery address.

No password, no form
registration takes one tap instead of filling a form
Contacts from the bank
phone and e-mail arrive verified, not typed by hand

Why a store needs it

Registration is the least pleasant step on the way to an order: invent a password, fill in a form, type an address. Almost every customer of the bank has a Sber ID, and signing in with it removes that step entirely.

Fewer abandoned carts

No password to invent and no form to fill in: the customer confirms the sign-in in the bank app and comes back to the store.
Reliable contacts

The phone number and the e-mail come from the bank, so orders carry fewer typos and the letters actually arrive.
No duplicate customers

If the customer already exists, Sber ID is linked to their account after a password confirmation.
No code to edit

The button joins the stock sign-in and registration forms: no theme templates to change.

One-tap registration

  • •  First name, last name, e-mail and phone come from Sber ID — the customer types nothing.
  • •  The delivery address is filled in when the bank hands it over, so checkout starts from a completed form.
  • •  A button on the registration page. A customer who opened the form does not have to fill it in at all.
  • •  No password needed. The account is created from the bank data, and the next sign-in works the same way.
The registration page: the form can be skipped — the account is created from the Sber ID data.

Settings and the look of the button

The add-on is set up in the administration panel: Client ID, Client Secret and the certificate from the Sber partner account. No code and no templates to edit.

  • •  Six button sizes and two themes, green and light: the button fits your layout instead of breaking it.
  • •  A personalised variant carrying the customer name.
  • •  A test mode to try everything on a staging store first.
  • •  A log of the Sber API calls in the stock event log: every call or errors only.

What the bank asks for

The store registers in the Sber ID partner account and receives a Client ID, a Client Secret and a certificate. The add-on manual walks through it step by step.

Linking and unlinking

Sber ID is linked to the customer account rather than replacing it. The customer manages the link in their account, the administrator — in the customer profile.

Customer personal data

A line under the Sber ID button links the terms of use and the personal data processing policy of the store. The addresses are set in the add-on settings; the policy defaults to the page selected in the GDPR add-on.

When a customer registers with Sber ID or links it to an account, the GDPR consent log records the line they saw, the document addresses, the sign-in method, the IP address and the browser. A regular registration in the store is recorded there as “Registration”, and only when the customer ticked the consent box.

How to start

STEP 1
Install the add-on

Through the Cart-Power Add-ons Manager — updates arrive the same way.
STEP 2
Register the store in Sber ID

In the partner account of the bank: return addresses and the certificate.
STEP 3
Fill in the credentials

Client ID, Client Secret and the certificate go into the add-on settings.
STEP 4
Check the button

Open the sign-in page: the button is already there. Its look is chosen in the settings.

What to know in advance

The storefront must run over HTTPS: the bank accepts secure return addresses only. The Sber ID credentials are issued to the store, not to the add-on developer — the store owner obtains them.

Frequently asked questions

What happens if the customer is already registered?

The store asks to confirm the password and links Sber ID to the existing account — no duplicate is created.

Does the customer have to fill in the registration form?

No. The registration page carries the Sber ID button: name, e-mail, phone and delivery address are filled in from the bank, and no password is needed.

Can Sber ID be unlinked?

Yes — by the customer in their account and by the administrator in the customer profile.

What is needed for the button to appear?

A Client ID, a Client Secret and a certificate from the Sber partner account. The store registers there itself; the manual describes the order of steps.

Where can I see what went wrong?

In the stock event log: the add-on writes the Sber API calls there — all of them or errors only, as configured.

Does it work in Multi-Vendor?

Yes, in all four editions.

Sber ID sign-in is set up in one evening. The add-on joins the stock sign-in and registration forms, and the credentials are issued to the store in the partner account of the bank.

Flagship products

Two add-ons that change how a store performs

Everything else we publish improves one screen. These two change the numbers: how customers find products, and how often they come back.

 

Add-on · Search & merchandising

Smart Search

Elasticsearch-powered search for large catalogues. The customer types two letters, sees products with images and prices, and buys from the dropdown — even after a typo or with the wrong keyboard layout.

Visitors who use the search bar are 24% of traffic and 44% of revenue, and convert about 2.5× better than people who only browse categories. If search returns nothing, up to 80% of them leave.
Constructor, Beyond Relevance Report 2025; Google Cloud × The Harris Poll, 2023

Catalogue size Sub-second results on 300,000+ products, Multi-Vendor included
Understands Typos, wrong keyboard layout, synonyms, word forms, SKUs, brands and attributes
Reporting Query analytics — what customers search for and which searches return nothing
Deployment Our cloud, or Elasticsearch on your own server

from $35/month

Plans by catalogue size · self-hosted from $1,215 one-time

Try it on a live catalogue: open the demo store and search with a deliberate typo.

 

Add-on · Mobile commerce

PowerApp — mobile app for your store

A native iOS and Android app running on your CS-Cart data: the same products, prices, stock, promotions, reward points and orders. There is no second catalogue to maintain — everything stays in the admin panel you already use.

A mobile site brings a customer in once; an app brings them back for free. Push notifications replace the retargeting budget you spend to buy the same customer a second time.

Platforms Native iOS and Android, published under your own developer account
Home screen Built in the admin panel from six block types, the same way you build website pages
Time to launch Under a week from purchase to submission for App Store and Google Play review
Compatibility CS-Cart and Multi-Vendor 4.18–4.20 · 11 client apps already live in the stores

Services

When no add-on solves it, we do the work

Fixed scope, written specification, a named project manager and a warranty on what we ship.

Custom CS-Cart development

Functionality the platform does not have: add-ons, marketplace mechanics, integrations with 1C, CRM, ERP, payment and delivery providers. We start from a written specification, not from an estimate on a phone call. Details →

CS-Cart upgrade

Move to the current version without losing data, custom code or add-ons. We audit every modification first, upgrade on a staging copy, adapt what breaks and switch over with little or no downtime. Details →

Speed and performance optimisation

Conversion falls by about 4.4% for every extra second of load time. We profile the server, the database and the front-end, then fix what actually costs the seconds — and show you the before-and-after numbers. Details →

Design for CS-Cart

Mobile-first storefront design built on CS-Cart's own template structure, so the layout survives the next platform upgrade instead of becoming a migration problem. Details →

SEO for CS-Cart

A technical audit of indexing, duplicates, redirects, structured data and Core Web Vitals — delivered as a prioritised fix list your developers can act on, or that we implement ourselves. Details →

How we work

What you get besides the code

Before we start

We discuss the goal, offer options and write the specification. You approve scope and price before development begins.

While we build

A named project manager reports progress on a fixed schedule. You always know what is in work and what is next.

Before release

A separate QA pass on every release — the developer who wrote the code is not the person who signs it off.

After handover

Documentation for everything we ship, plus a warranty on the modifications and the project.

Tell us what the store needs to do

Describe the task in a couple of sentences and we will come back with options, a scope and a price. The consultation is free, and we will say plainly if a ready-made add-on already solves it.
