Object catalog

What Stacksync syncs in Easypost.

These objects sync between Easypost and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Easypost exposes them.

Shipment
The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination.
Address
Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream.
Parcel
Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches.
Rate
Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly.
Tracker
Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves.
Batch
Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders.
CarrierAccount
Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts.
Webhook
Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync.
API surface

How Stacksync connects to Easypost.

The connector runs on Easypost's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
REST API (EasyPost API v2, https://api.easypost.com/v2)
Authentication
HTTP Basic auth with the API key as the username and an empty password (Bearer token also accepted); separate Test and Production keys
Change detection
Webhooks deliver an Event via HTTP POST on object changes (e.g. tracker.updated); historical pulls via list/index endpoints using before_id/after_id cursor pagination
Rate limits
Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests

Use cases

What teams run on the Easypost connector.

EasyPost is the multi-carrier shipping API e-commerce and logistics teams use to rate, buy labels, verify addresses, and track parcels across USPS, UPS, FedEx, DHL, and 100+ carriers. Fulfillment engineers and ops own it; finance watches the shipping spend it generates. Every shipment carries a label, a chosen rate, a tracker, and address data - the record e-commerce, support, and finance want joined to their OMS, ERP, warehouse, and CRM.

  • E-commerce and DTC operations
  • Logistics and fulfillment engineering
  • Warehouse and 3PL operations
  • Finance and RevOps (shipping-cost analytics)

  1. When an order is ready to ship in an OMS, ERP, or database, create an EasyPost Shipment, buy the lowest qualifying Rate, and write the label URL and tracking code back onto the order.

  2. Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.

  3. Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.

  4. Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

  5. Pull Shipment, Rate, and Refund records into a warehouse to report shipping cost per carrier and service and reclaim postage on labels that were never scanned.

  6. Batch-create and buy labels for a day's orders, generate a ScanForm, and write each label and tracking code back into the fulfillment system.

FAQ

Easypost connector FAQ

What can I sync with the Easypost connector?

Easypost's core objects — Shipment, Address, Parcel, Rate and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Easypost?

Via REST API (EasyPost API v2, https://api.easypost.com/v2), authenticated with HTTP Basic auth with the API key as the username and an empty password (Bearer token also accepted); separate Test and Production keys. Changes are detected as follows — webhooks deliver an Event via HTTP POST on object changes (e.g. tracker.updated); historical pulls via list/index endpoints using before_id/after_id cursor pagination. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Easypost connector two-way?

Yes. Changes made in Easypost propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does an Easypost integration take to set up?

Most Easypost integrations go live in minutes: authenticate Easypost and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Easypost data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Easypost data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
