Why teams connect Easypost and OpenSearch

Give your engineers Easypost's products, orders, and customers in OpenSearch: read them with normal queries, write inventory and prices back through the sync, and skip the storefront API.

E-commerce data sits behind an API built for the storefront, not for your internal systems. Teams that need those records, for order routing, inventory logic, reporting, or back-office tools, end up writing integration code against a rate-limited API and maintaining it through every catalog change and platform upgrade.

Stacksync mirrors CarrierAccount, Webhook, Shipment, Address from Easypost into OpenSearch and keeps both sides consistent in real time. Whatever Easypost holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in OpenSearch, such as new prices, stock levels, or fulfillment status, sync back into Easypost with its validations respected.

Merchandising and operations keep working in the storefront, engineers keep working in the database, and neither side has to reconcile against a nightly export.

Common use cases

  • 01 Backfill or rebuild indexes from a database after mapping changes without hand-written ETL.
  • 02 Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • 03 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.
  • 04 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.

Common sync patterns

Keep catalog and inventory current

Prices, stock levels, or product details maintained in OpenSearch sync back onto Easypost, so the storefront shows what your systems treat as true.

Order data where your code can use it

Orders and their status become rows in OpenSearch for routing, fulfillment, and reporting, without polling the platform.

Controlled write-back

Choose exactly which tables and fields may flow from OpenSearch back into Easypost, keeping the store authoritative on what it owns.

What you can sync between Easypost and OpenSearch

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 OpenSearch objects How this pairing syncs
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. Documents JSON records written via the index and bulk APIs and read via search queries Batch is specific to Easypost and Documents to OpenSearch — 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. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills CarrierAccount is specific to Easypost and Index aliases to OpenSearch — 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. Index templates Mapping and settings presets applied to new indexes a sync creates Webhook is specific to Easypost and Index templates to OpenSearch — 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. Ingest pipelines Server-side processors that transform documents as they are written Shipment is specific to Easypost and Ingest pipelines to OpenSearch — each maps to any object or custom field on the other side.
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. Data streams Append-oriented time-series storage for logs and events pushed from source systems Address is specific to Easypost and Data streams to OpenSearch — 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. Snapshots Backup artifacts, relevant when reseeding an index from a repository Parcel is specific to Easypost and Snapshots to OpenSearch — each maps to any object or custom field on the other side.

How changes propagate between Easypost and OpenSearch

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

OpenSearch Easypost Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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.
  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.
