Salesforce Commerce Cloud (formerly Demandware) is a leading enterprise eCommerce platform designed to provide scalable, omnichannel shopping experiences. This DIY Developer Guide for Salesforce Commerce Cloud offers a structured, scalable, and secure approach for building custom integrations with ERP systems, CRMs, fulfillment providers, and marketing automation platforms.

Prerequisites for Salesforce Commerce Cloud Integrations

• Salesforce B2C Commerce Account and API Access (OCAPI, SCAPI Credentials)
• Familiarity with:
  • RESTful APIs and SOAP APIs
  • OAuth 2.0 Authentication
  • JSON and XML data formatting
• Tools: Postman, Salesforce Commerce API Documentation, SDKs (Node.js, Java)

Step 1: Authentication for Salesforce Commerce Cloud Integrations

Salesforce Commerce Cloud uses OAuth 2.0 and custom client authentication for secure API access.

OAuth 2.0 Authentication Example:

POST https://account.demandware.com/dw/oauth2/access_token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=YOUR_CLIENT_ID
&client_secret=YOUR_CLIENT_SECRET

Use the returned access_token for subsequent API requests.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Products
• Customers
• Orders
• Inventory
• Promotions and Campaigns

Process:

• Review Open Commerce API (OCAPI) and Shopper APIs (SCAPI) documentation.
• Map external system fields (e.g., SKU, order ID, customer email) to Salesforce Commerce Cloud objects.

Important considerations:

• Managing custom attributes and extensibility settings
• Handling inventory per location
• Ensuring compliance with promotion and pricing rules

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to Salesforce Commerce Cloud): Push product updates, inventory adjustments, customer records.
• Outbound (from Salesforce Commerce Cloud): Retrieve orders, customer data, and catalog information.

Example: Creating a New Customer

POST /s/-/dw/data/v21_3/customers
{
  "customer_id": "john.doe@example.com",
  "login": "john.doe@example.com",
  "password": "StrongPassword123"
}

Example: Fetching Orders

GET /s/-/dw/data/v21_3/orders
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture Salesforce-specific error codes and messages.
• Implement retries for 429 (rate limit) and 5xx server errors.

Pagination:

• Use start and count parameters for paginated endpoints.

Example:

GET /s/-/dw/data/v21_3/products?start=0&count=50

Step 5: Testing and Validation

• Use Salesforce Commerce Cloud sandbox environments for testing.
• Validate product synchronization, order processing, and customer data flows.
• Conduct load testing for high-traffic events like seasonal sales.

Step 6: Deployment and Security

• Deploy securely using AWS, Azure, or GCP.
• Store OAuth tokens securely using secret management tools.
• Enforce HTTPS/TLS encryption for all API transactions.
• Set up detailed logging, real-time monitoring, and proactive alerting.

Step 7: Maintenance and Monitoring

• Monitor Salesforce Commerce Cloud release notes for API updates.
• Set up alerts for authentication failures and integration errors.
• Track KPIs like order processing rates, inventory sync accuracy, and customer profile completeness.

Optional Enhancements

• Middleware integration (MuleSoft, Celigo, Boomi) for complex workflows
• Webhooks or event-driven architecture for real-time updates on orders and inventory
• Custom dashboards for real-time operational and sales performance metrics

Summary

Building custom Salesforce Commerce Cloud integrations allows enterprises to automate eCommerce workflows, optimize inventory management, and deliver personalized shopping experiences. This DIY Developer Guide for Salesforce Commerce Cloud provides a secure, scalable, and effective roadmap for high-performance integration development.
