FedEx Web Services API
FedEx REST API — direct carrier integration for shipping rate quotes, label generation, package tracking, and pickup scheduling across FedEx Express, Ground, and Freight services, enabling agents to build FedEx-native shipping workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
PCI-DSS compliant for payment card data handling. TLS enforced. OAuth 2.0 with short-lived tokens (1 hour). No scope granularity on tokens. FedEx is an established carrier with strong enterprise security practices.
⚡ Reliability
Best When
You ship primarily with FedEx, have negotiated carrier rates, and need direct carrier integration for maximum control and access to all FedEx service types.
Avoid When
You ship with multiple carriers or need quick integration — a multi-carrier aggregator like ShipEngine saves significant integration time.
Use Cases
- • Agents generating FedEx shipping labels directly for high-volume shippers who negotiate carrier rates
- • Rate shopping — agents querying FedEx rates for time-sensitive shipments requiring Express service guarantees
- • Package tracking — agents monitoring FedEx shipment status and sending proactive delivery notifications to customers
- • Pickup scheduling — agents scheduling FedEx package pickups programmatically rather than through the FedEx portal
- • Freight quotes — agents obtaining LTL and FedEx Freight rate quotes for heavier shipments over 150 lbs
Not For
- • Multi-carrier shipping — use ShipEngine or EasyPost for carrier-agnostic rate comparison and label generation
- • Smaller shippers without FedEx account — negotiated rates require volume commitments; retail rates are expensive
- • Real-time tracking with webhooks — FedEx tracking requires polling; use ShipEngine or EasyPost for unified webhook tracking
Interface
Authentication
OAuth 2.0 client credentials flow. API key + secret from FedEx developer portal generates access token. Tokens expire after 3600 seconds — agents must refresh. FedEx account number required for rate quotes and label generation. Production access requires FedEx business account.
Pricing
API access is free — costs are per-shipment carrier charges. Negotiated rates require FedEx account setup. Retail rates significantly higher than negotiated rates. Developer sandbox available for testing.
Agent Metadata
Known Gotchas
- ⚠ OAuth access tokens expire every 3600 seconds — agents must implement token refresh before expiry in long-running processes
- ⚠ Sandbox and production environments have different credentials — never mix test credentials with production FedEx account numbers
- ⚠ Service type codes are FedEx-specific and not human-readable — agents must map service names to codes (e.g., PRIORITY_OVERNIGHT)
- ⚠ FedEx account number required for negotiated rates — agents must include account number in requests or retail rates apply
- ⚠ No webhook/push tracking — agents must poll FedEx tracking endpoint; use a multi-carrier aggregator for webhook-based tracking
