Shipping Concepts

Rate Shopping

EasyPost aggregates rates from all connected carriers, allowing you to compare prices and delivery times in a single API call. The returned rates include retail and negotiated pricing when available.

Label Formats

  • PDF: Best for printing on standard printers
  • PNG: Image format for digital display
  • ZPL: Zebra Programming Language for thermal printers
  • EPL2: Eltron Programming Language for thermal printers

Predefined Packages

Common carrier packages are available as predefined options:

  • USPS: FlatRateEnvelope, SmallFlatRateBox, MediumFlatRateBox, LargeFlatRateBox
  • FedEx: FedExEnvelope, FedExPak, FedExBox
  • UPS: UPSLetter, UPSExpressBox

SmartRates

SmartRates provide delivery time predictions based on historical data, offering confidence percentiles (50%, 75%, 90%, etc.) for estimated delivery.

Error Handling

The node provides detailed error information from EasyPost:

  • ADDRESS.VERIFICATION.FAILURE: Address could not be verified
  • RATE.UNAVAILABLE: No rates available for the shipment
  • SHIPMENT.POSTAGE.FAILURE: Label purchase failed
  • TRACKER.CREATE.ERROR: Tracking number not recognized

Errors include specific field information when available, helping identify exactly what needs to be corrected.

Security Best Practices

  1. Use Test Keys in Development: Always use EZTEST keys during development to avoid accidental charges
  2. Secure Your API Keys: Never expose API keys in client-side code or logs
  3. Validate Addresses: Use address verification before creating shipments to reduce failed deliveries
  4. Webhook Secrets: Configure webhook secrets to verify incoming webhook payloads
