GraphQL vs REST for Shipping APIs: A Practical Comparison
Every shipping platform debate: should we build our API as REST or GraphQL? After building integrations with 180+ carriers (all REST) and serving thousands of e-commerce merchants, here's the practical answer.
REST Wins for Carrier Integration
Every major carrier API is REST-based. USPS, FedEx, UPS, DHL — all REST with JSON payloads. You'll always need a REST client layer to talk to carriers, regardless of what you expose to your own users.
Trying to wrap REST carrier APIs behind a GraphQL layer adds complexity without much benefit. You can't batch carrier API calls through a GraphQL resolver the way you can with database queries.
GraphQL Wins for Frontend Data Fetching
Where GraphQL shines is your internal API — the layer between your frontend and your shipping backend. A single query can fetch everything an order detail page needs: tracking number, carrier info, current status, estimated delivery, addresses, label URL, and rate quotes. With REST, the same page might need 3-4 separate API calls.
The Hybrid Approach
Most modern shipping platforms use both:
| Layer | Protocol | Why |
|---|---|---|
| Frontend to Backend | GraphQL | Flexible queries, reduced round-trips |
| Backend to Carriers | REST | Required by all carrier APIs |
| Webhooks (inbound) | REST | Carriers send POST to your endpoints |
| Internal microservices | gRPC or REST | Low latency, type safety |

When REST Is Simpler
For these shipping operations, REST endpoints are cleaner:
- Label generation: POST /labels — single resource creation
- Tracking lookup: GET /tracking/:id — simple resource fetch
- Rate quotes: POST /rates — predictable request/response
When GraphQL Helps
- Dashboard pages that aggregate data from multiple services
- Mobile apps where bandwidth matters (fetch only needed fields)
- Multi-tenant systems where different merchants need different data shapes
Performance Consideration
GraphQL can create N+1 query problems in shipping contexts. If a query fetches 50 orders with their tracking statuses, a naive resolver will make 50 separate carrier API calls. Use DataLoader to batch these — collect all tracking numbers and make a single batch API call to the carrier.
Bottom line: Use REST for carrier integrations, consider GraphQL for your customer-facing API if you have complex data needs.
