B2c Scapi Shopper

Shopper Commerce APIs (SCAPI)

This skill guides you through consuming standard Shopper APIs for building headless commerce experiences. Shopper APIs are RESTful endpoints designed for customer-facing storefronts.

Note: For creating custom API endpoints, see b2c-custom-api-development. This skill focuses on consuming standard Shopper APIs.

Scope & grounding

This skill provides quick-start patterns and examples for B2C Commerce Shopper APIs (SCAPI) used in headless storefronts — authentication, checkout, product APIs, and Shopper Context. The examples are version-agnostic and illustrative. Before answering questions that reference specific API versions, authentication flows, quota limits, default scopes, or before emitting code the user will run, confirm current details via b2c docs search/b2c docs read (CLI) or the docs_search/docs_read MCP tools. The official Commerce API documentation at developer.salesforce.com is the authoritative source for API specifications, current authentication patterns, and version-specific behavior.

Overview

Shopper APIs are designed for frontend commerce applications:

• Client: PWA Kit, composable storefronts, mobile apps
• Authentication: SLAS (Shopper Login and API Access Service)
• Response Time: < 10 seconds (HTTP 504 if exceeded)
• CORS: Not supported - use a reverse proxy or BFF (Backend for Frontend)

Base URL Structure

https://{shortCode}.api.commercecloud.salesforce.com/{apiFamily}/{apiName}/v1/organizations/{organizationId}/{resource}?siteId={siteId}

Example:

https://kv7kzm78.api.commercecloud.salesforce.com/product/shopper-products/v1/organizations/f_ecom_zzte_053/products/25518823M?siteId=RefArchGlobal

Note: Shopper Baskets API supports both v1 and v2. See Shopper Baskets API reference or b2c docs read commerce-api/work-with-baskets-orders for current version guidance.

Configuration Values

Find these in Business Manager: Administration > Site Development > Salesforce Commerce API Settings

Authentication

Shopper APIs require SLAS tokens. SLAS supports guest and registered shopper flows.

Create SLAS Client

# Create client with default scopes for a shopping app
b2c slas client create \
  --tenant-id zzte_053 \
  --channels RefArchGlobal \
  --default-scopes \
  --redirect-uri http://localhost:3000/callback

See b2c-slas skill for full client management.

Get Guest Token

Illustrative of the flow; confirm current SLAS authentication patterns (guest/registered, public/private client, PKCE) with b2c docs read commerce-api/slas.

const response = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/shopper/auth/v1/organizations/${orgId}/oauth2/token`,
    {
        method: 'POST',
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Authorization': `Basic ${btoa(clientId + ':' + clientSecret)}`
        },
        body: new URLSearchParams({
            grant_type: 'client_credentials',
            channel_id: siteId
        })
    }
);

const { access_token, refresh_token } = await response.json();

Required Scopes

All Shopper API scopes must be configured on your SLAS client. See Scopes Reference for the complete list.

API Families

Shopper Products

Retrieve product details, pricing, and availability.

// Get product by ID
const product = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/product/shopper-products/v1/organizations/${orgId}/products/${productId}?siteId=${siteId}`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

// Get multiple products
const products = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/product/shopper-products/v1/organizations/${orgId}/products?ids=prod1,prod2,prod3&siteId=${siteId}`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

Shopper Search

Product search and suggestions.

// Search products
const results = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/search/shopper-search/v1/organizations/${orgId}/product-search?siteId=${siteId}&q=shirt&limit=25`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

// Get search suggestions
const suggestions = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/search/shopper-search/v1/organizations/${orgId}/search-suggestions?siteId=${siteId}&q=shi`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

Shopper Baskets

Create and manage shopping carts. See Checkout Flow Reference for the complete flow.

// Create basket
const basket = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/checkout/shopper-baskets/v1/organizations/${orgId}/baskets?siteId=${siteId}`,
    {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${accessToken}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({})
    }
).then(r => r.json());

// Add item to basket
await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/checkout/shopper-baskets/v1/organizations/${orgId}/baskets/${basketId}/items?siteId=${siteId}`,
    {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${accessToken}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify([{
            productId: '25518823M',
            quantity: 1
        }])
    }
);

Shopper Orders

Submit orders and retrieve order history.

// Create order from basket
const order = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/checkout/shopper-orders/v1/organizations/${orgId}/orders?siteId=${siteId}`,
    {
        method: 'POST',
        headers: {
            'Authorization': `Bearer ${accessToken}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            basketId: basket.basketId
        })
    }
).then(r => r.json());

The order POST is the first phase. It commits an order in CREATED; it does not authorize or place it. Next, update each required order payment instrument with PATCH /orders/{orderNo}/payment-instruments/{paymentInstrumentId}. That endpoint invokes dw.order.payment.authorizeCreditCard or dw.order.payment.authorize, then the default order-PI afterPATCH implementation places the order after authorized coverage reaches the order total. Treat the returned NEW order as success. On a deterministic payment failure, call POST /orders/{orderNo}/actions/fail?reopenBasket=true with an appropriate reason code. Preserve a CREATED order when provider state is indeterminate. See b2c-hooks and b2c-ordering. Confirm version-specific request fields with the Shopper Orders schema and hook signatures with b2c docs read commerce-api/hook-method-details.

Shopper Customers

Customer registration, login, and account management.

// Get customer profile (registered shopper)
const customer = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/customer/shopper-customers/v1/organizations/${orgId}/customers/${customerId}?siteId=${siteId}`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

Shopper Context API

Maintain personalization state across requests using the Shopper Context API. The siteId query parameter is required for all Shopper Context operations.

// Set shopper context
await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/shopper/shopper-context/v1/organizations/${orgId}/shopper-context/${usid}?siteId=${siteId}`,
    {
        method: 'PUT',
        headers: {
            'Authorization': `Bearer ${accessToken}`,
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            effectiveDateTime: new Date().toISOString(),
            sourceCode: 'SUMMER2024',
            customerGroupIds: ['VIP', 'Loyalty']
        })
    }
);

When to Set Context

• Initial visit/login: Immediately after obtaining SLAS token
• Token refresh: Reuse existing USID for session continuity
• Login transitions: When shopper changes from guest to registered (or vice versa)
• Logout: Clear context explicitly

Quota Limits

Strategies to manage quota:

• Use lower TTL (1-2 days for registered shoppers)
• Reuse USIDs for the same shopper
• Explicitly log out shoppers to delete context

Best Practices

• Set context immediately after obtaining SLAS token
• Use the USID from the SLAS token response
• Context TTL: 1 day (guest), 7 days (registered)
• Security: Use private SLAS clients only, call from BFF (not browser)
• Don't use Shopper Context for data that's automatically set (like geolocation)

Performance Optimization

Use select Parameter

Return only needed fields to reduce response size:

// Only return specific product fields
const product = await fetch(
    `https://${shortCode}.api.commercecloud.salesforce.com/product/shopper-products/v1/organizations/${orgId}/products/${productId}?siteId=${siteId}&select=(id,name,price,images)`,
    {
        headers: { 'Authorization': `Bearer ${accessToken}` }
    }
).then(r => r.json());

Use expand Carefully

Expansions increase response time and reduce cache effectiveness:

// Expand availability (60-second cache TTL)
const product = await fetch(
    `...?expand=availability,images,prices`,
    { headers: { 'Authorization': `Bearer ${accessToken}` } }
).then(r => r.json());

Consider separate requests instead of low-cache expansions.

Enable Compression

Always enable HTTP compression in your client for faster responses.

See Common Patterns Reference for more optimization patterns.

Debugging

Correlation IDs

Include correlation IDs for request tracking:

const response = await fetch(url, {
    headers: {
        'Authorization': `Bearer ${accessToken}`,
        'correlation-id': crypto.randomUUID()
    }
});

// Check response header for SCAPI-generated ID
const scapiCorrelationId = response.headers.get('sfdc_correlation_id');

Search Log Center with: externalID:({correlation-id})

Verbose Logging

Enable verbose logging for debugging:

const response = await fetch(url, {
    headers: {
        'Authorization': `Bearer ${accessToken}`,
        'sfdc_verbose': 'true'
    }
});

Find logs in Log Center under scapi.verbose category.
