Always check which version supports your specific endpoint.

Never embed credentials in client-side code. Use environment variables.

Monitor headers: X-Rate-Limit-Requests-Left, X-Rate-Limit-Time-Reset-Ms Implement exponential backoff with jitter for retries.

Always include channel_id when working with multi-storefront stores.

1. Build a new integration (REST API, webhooks, data sync)
2. Create a headless storefront (GraphQL Storefront, Next.js/Catalyst)
3. Develop a BigCommerce app (single-click app, marketplace)
4. Work with specific API (Catalog, Orders, Customers, Payments)
5. Debug an API issue (errors, authentication, rate limits)
6. Set up webhooks and event handling
7. Something else

Wait for response before proceeding.

After reading the workflow, follow it exactly.

<verification_loop> After every API operation:

# 1. Check response status
# 200/201 = Success
# 4xx = Client error (check request)
# 5xx = Server error (retry with backoff)

# 2. Verify rate limit headers
X-Rate-Limit-Requests-Left: [remaining]
X-Rate-Limit-Time-Reset-Ms: [reset time]

# 3. For mutations, verify the change
GET the resource to confirm state

Report to user:

• "API call: [status]"
• "Rate limit remaining: [X]"
• "Data verified: [confirmation]" </verification_loop>
