Developer-friendlyshippingAPIforwarehouseautomation.
Nautilus leverages EasyPost's unified API to provide carrier-agnostic shipping, address verification, and insurance across all major carriers from a single integration.
Inventory data, where you need it.
Three things the EasyPost integration does well — and that you'd otherwise be doing manually.
Address verification
Validate shipping addresses before label creation to reduce returns.
Insurance automation
Auto-insure high-value shipments based on configurable thresholds.
Customs forms
International customs documentation generated automatically.
Bidirectional sync. No manual entry.
Data moves between Nautilus and EasyPost in both directions, near-real-time.
- Pick lists
- Order weights
- Packing slips
- Bin locations
- Tracking numbers
- Carrier rates
- Label data
- Delivery status
Four steps to live.
Under 10 minutes for most teams. The full health check takes longer but doesn't block sync.
Connect
Authenticate with one click. Nautilus uses OAuth — no API keys to copy, no credentials to store.
Map
Match your products, locations, and accounts. Nautilus auto-maps by SKU where possible.
Sync
Enable bidirectional sync. Changes in either system reflect in the other within 30 seconds.
Verify
Run the sync health check. Nautilus flags any mismatches before they become problems.
What the integration does, in numbers.
Quick answers.
How long does setup take?
Most customers are syncing in under 10 minutes. Enterprise environments with custom field mappings can take 30 minutes to an hour.
What if a sync fails?
Nautilus retries with exponential backoff for 24 hours. After that, the record is flagged in your dashboard for manual review. Sync failures never block your warehouse operations.
Can I limit what syncs?
Yes. Granular controls let you sync specific products, locations, or even specific fields. Most customers start with everything on and tighten over time.
Is the integration included in all plans?
This integration is included in Pro and Enterprise. Free plans can install but with limits on sync frequency.
