DIY Developer Guide: Building Custom Integrations for BigCommerce B2B
A guide to building custom B2B integrations with BigCommerce B2B Edition for wholesale operations, customer-specific pricing, and quote management.
Overview
BigCommerce B2B Edition extends the platform with wholesale-specific features including customer groups, price lists, quote management, and company accounts. 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

- 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
