Learn how to build custom integrations with 3dcart (Shift4Shop) APIs for eCommerce operations, product management, and order processing.
Overview
3dcart (now Shift4Shop) is an eCommerce platform providing online store building, product management, and order processing. This guide covers building custom integrations with ERP and fulfillment systems.
Prerequisites
- 3dcart/Shift4Shop store with API access
- Familiarity with RESTful APIs, OAuth, and JSON data structures

Map 3dcart product structure to your ERP item master.
Step 3: Building Integration Flows
- Inbound (to 3dcart): Update inventory, create products, manage categories
- Outbound (from 3dcart): Retrieve orders, customer data, product catalogs
Step 4: Error Handling and Rate Limiting
Handle API pagination and rate limits. Implement retry logic for transient errors.
Step 5: Security Best Practices
- Store API tokens securely
- Use HTTPS for all communications
- Validate webhook payloads

Step 6: Testing and Validation
- Test against development stores
- Validate product sync accuracy
- Verify order retrieval and processing
Step 7: Deployment and Monitoring
- Monitor API usage and error rates
