BigCommerce API Integration & Troubleshooting
Troubleshoot & Build BigCommerce API Integrations with Structured Workflows
What You Can Do
This skill guides you through BigCommerce API authentication, endpoint validation, and systematic error diagnosis. You'll resolve integration failures faster, validate request payloads before deployment, and implement production-ready REST and GraphQL integrations. You'll move from debugging guesswork to structured troubleshooting with decision trees, error mapping, and verified solutions.
Features
diagnose OAuth token issues, scope mismatches, and credential validation errors
verify endpoint parameters, payload structure, and required fields before deployment
translate BigCommerce error responses and status codes into root causes and fixes
choose the right endpoint type for your use case with performance tradeoffs
set up subscriptions, verify signatures, and handle event delivery failures
implement exponential backoff, batch processing, and queue management
ready-to-use API calls for common endpoints, paginated requests, and bulk operations
validate authentication, data persistence, error handling, and production readiness
Example Output
Diagnosing a 401 Authentication Error
You provide: An API request returning 401 Unauthorized with a bearer token
Claude returns:
- Scope check: Current token has
store_v2_products_readbut you're calling/v3/orders(requiresstore_v2_orders_read) - Fix: Regenerate OAuth token with both scopes
- Verify request:
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
https://api.bigcommerce.com/stores/{store-hash}/v3/catalog/products
Validating a Product Sync Integration
You provide: Your planned API sequence (GET products → extract ID → POST attributes)
Claude returns:
- Rate limit analysis: 100 requests/hour = 1 per 36 seconds; your loop needs 2-second delays
- Scope validation: ✓
store_v2_products_read+store_v2_customersboth required - Pagination template with cursor handling
- Retry strategy: exponential backoff for 429 errors
Setting Up Product Update Webhooks
You provide: Webhook destination URL
Claude returns:
- Registration steps in BigCommerce Control Panel
- Signature verification code (Node.js/Python templates)
- Sample event payload with field descriptions
- Monitoring checklist to verify delivery
