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.

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. Use v2 for newer features.

Configuration Values

Value Description Example
shortCode 8-character API routing code kv7kzm78
organizationId Instance identifier f_ecom_zzte_053
siteId Site/channel name RefArchGlobal

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

bash
# 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

javascript
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 Family Scope
Products sfcc.shopper-products
Search sfcc.shopper-product-search
Baskets sfcc.shopper-baskets-orders.rw
Orders sfcc.shopper-baskets-orders
Customers sfcc.shopper-customers.login, sfcc.shopper-myaccount.rw

API Families

Shopper Products

Retrieve product details, pricing, and availability.

javascript
// 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.

javascript
// 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.

javascript
// 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.

javascript
// 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());

Shopper Customers

Customer registration, login, and account management.

javascript
// 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.

javascript
// 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

Environment Limit
Non-production 5,000 records
Production 1,000,000 records

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:

javascript
// 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:

javascript
// 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:

javascript
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:

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

Find logs in Log Center under scapi.verbose category.
