Why teams connect Easypost and Hyperline

Turn every Easypost order into clean revenue: Hyperline and Easypost keep customers, orders, and payment status aligned in real time, in both directions.

Easypost runs the storefront — the catalog, the orders, and the buyers placing them. Hyperline records the money behind those orders — invoices, revenue, payments, and the ledger the business closes on. The overlap is every customer, order, and product both sides need to agree on, and when that overlap is bridged by CSV export or an overnight batch, finance reconciles against stale numbers while the store quotes prices or stock the books no longer recognize.

Stacksync syncs Customers, Subscriptions, Products / prices, Invoices in Hyperline with Webhook, Shipment, Address, Parcel in Easypost field by field, in real time, and in both directions. You decide which system owns which fields — an order's totals from Easypost, its paid-or-overdue state from Hyperline — and Stacksync keeps every copy consistent and resolves conflicts by the rules you set.

The result is one shared record of who bought what and whether it has been paid, so the storefront, support, and the finance team all read from the same current data instead of re-keying it between systems.

Common use cases

  • 01 Keep plan and entitlement state consistent between Hyperline and the application database that enforces feature access.
  • 02 Create billing customers automatically when new accounts appear in the CRM or product database.
  • 03 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.
  • 04 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

Common sync patterns

Where Hyperline is the money system of record: payment status on the order

Paid, overdue, and refunded state from Hyperline lands on the order or account in Easypost, so the store and support see what has actually been collected.

One customer master

Where both systems keep customer or buyer records, an edit in either propagates to the other, ending duplicate accounts and mismatched contact details.

Catalog and pricing stay aligned

Products, SKUs, and prices maintained on one side propagate to the other, so what the store sells and what the ledger books stay in step.

What you can sync between Easypost and Hyperline

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Easypost objects Hyperline objects How this pairing syncs
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. Billable events Metered consumption events ingested to drive usage-based charges. Address is specific to Easypost and Billable events to Hyperline — each maps to any object or custom field on the other side.
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Credit notes Adjustments and refunds synced for accurate revenue reporting. Parcel is specific to Easypost and Credit notes to Hyperline — each maps to any object or custom field on the other side.
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. Customers Billing accounts that syncs match against CRM and product records. Rate is specific to Easypost and Customers to Hyperline — each maps to any object or custom field on the other side.
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. Subscriptions Active plans and their lifecycle state, synced to show billing status elsewhere. Tracker is specific to Easypost and Subscriptions to Hyperline — each maps to any object or custom field on the other side.
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. Products / prices The catalog of products and price configurations referenced by subscriptions. Batch is specific to Easypost and Products / prices to Hyperline — each maps to any object or custom field on the other side.
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Invoices Issued billing documents synced into accounting and reporting systems. CarrierAccount is specific to Easypost and Invoices to Hyperline — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Hyperline

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Easypost Hyperline Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

DeliveryEach detected change is written to Hyperline through its API, with automatic retries and rate-limit backoff.

Hyperline Easypost Sub-second propagation

DetectionHyperline notifies Stacksync of record changes through webhook events. Webhooks for billing events, with polling as a fallback.

DeliveryEach detected change is written to Easypost through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Easypost: 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.
  • Hyperline: Subject to the platform's API rate limits.
