This guide covers B2B-specific integration patterns. ## Prerequisites - BigCommerce B2B Edition store with API access - Familiarity with RESTful APIs, B2B commerce concepts, and JSON data structures - Tools: Postman, BigCommerce B2B API Documentation ## Step 1: Authentication BigCommerce B2B uses the same **OAuth/API Token** authentication as standard BigCommerce, with additional B2B-specific endpoints. ## Step 2: Endpoint Discovery and Data Mapping **Common B2B Resources:** Companies, Price Lists, Quotes, Customer Groups, Shared Shopping Lists, Purchase Orders. Map B2B customer hierarchies and price lists to your ERP account structure. ## Step 3: Building Integration Flows - **Inbound (to BigCommerce):** Sync customer-specific pricing, manage company accounts, update credit limits - **Outbound (from BigCommerce):** Retrieve quotes, purchase orders, company activity ## Step 4: Error Handling and Rate Limiting Handle company-level data isolation. Implement price list versioning and conflict resolution. ## Step 5: Security Best Practices - Implement company-level access controls - Encrypt sensitive pricing data - Validate B2B-specific webhook payloads - Audit company account changes ## Step 6: Testing and Validation - Test B2B workflows with multiple company accounts - Validate customer-specific pricing accuracy - Verify quote-to-order conversion flows ## Step 7: Deployment and Monitoring - Monitor B2B-specific API endpoints - Alert on pricing sync failures - Track B2B conversion metrics ## When to Use a Managed Platform For B2B operations integrating BigCommerce with ERP, CRM, and pricing systems, a managed integration platform like APIWORX provides unified B2B commerce orchestration. ### See the APIWORX platform in action Tell us about your systems and we'll build a tailored automation plan within 24 hours.
