Why teams connect Easypost and Recurly

Turn every Easypost order into clean revenue: Recurly 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. Recurly 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 Plans, Invoices, Transactions, Line Items in Recurly with CarrierAccount, Webhook, Shipment, Address 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 Recurly — 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 Trigger revenue-recognition or ERP entries when new_subscription and canceled_subscription webhooks fire.
  • 02 Post usage records to Measured Units on metered Subscriptions from a metering database before each bill run.
  • 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

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.

Refunds and credits reconcile

Refunds, cancellations, and credit notes raised in either system update the corresponding record in the other, keeping balances honest on both sides.

Where Easypost originates orders: sales flow into the books

A new or updated order in Easypost creates or updates the matching invoice or revenue record in Recurly, so billing and reporting start without re-entry.

What you can sync between Easypost and Recurly

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 Recurly objects How this pairing syncs
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. Measured Units and Usage Metered-billing units; usage records are posted to a subscription before each bill run for consumption-based pricing. Rate is specific to Easypost and Measured Units and Usage to Recurly — 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. Accounts Customer/billing entity records keyed by account_code; the anchor most subscriptions and invoices hang off. Synced two-way with CRM accounts or a customer database. Tracker is specific to Easypost and Accounts to Recurly — 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. Subscriptions Recurring subscription records tied to an Account and a Plan, with state, term, and next-bill date. Core object, synced two-way to drive provisioning and reporting. Batch is specific to Easypost and Subscriptions to Recurly — 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. Plans The product and pricing catalog (plan codes, intervals, add-ons); usually mastered in Recurly and read out, or mirrored from a product database. CarrierAccount is specific to Easypost and Plans to Recurly — each maps to any object or custom field on the other side.
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. Invoices Charge and credit billing documents; read-heavy for revenue reporting, and creatable through Purchases for one-off charges. Webhook is specific to Easypost and Invoices to Recurly — each maps to any object or custom field on the other side.
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. Transactions Individual payment attempts — captures, refunds, and voids; typically read into a warehouse for reconciliation and dunning analysis. Shipment is specific to Easypost and Transactions to Recurly — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Recurly

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 Recurly 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 Recurly through its API, with automatic retries and rate-limit backoff.

Recurly Easypost Sub-second propagation

DetectionRecurly notifies Stacksync of record changes through webhook events. Webhooks (JSON or XML, one format per endpoint) for account, subscription, payment, and invoice events, plus incremental polling of list endpoints.

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.
  • Recurly: Production sites default to 1,000 requests/min with only GET requests counting toward the limit; sandbox sites 400/min with all requests counting; the limit is a sliding 5-minute window, X-RateLimit headers report the quota, and breaches return HTTP 429.
