Why teams connect Easypost and Greenplum

Make Greenplum the analytics and enrichment layer behind Easypost: orders, products, and customers stay current in both directions.

Greenplum is the analytical store where the business joins, models, and reports on its data; Easypost runs the storefront, catalog, and transactions that generate most of it. The overlap is every record that has to be counted and enriched on one side and acted on the other — and when the bridge is a nightly export, the warehouse reports on yesterday while the store operates without the segments and metrics the warehouse just computed.

Stacksync syncs Views, External tables, Rows, Databases in Greenplum with Webhook, Shipment, Address, Parcel in Easypost field by field, in real time, and in both directions. Transactional records land in the warehouse as they change, computed attributes and cleaned catalog data flow back to the store, and you decide which system owns which fields so Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • 02 Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • 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

Inventory and order status reconciled

Stock levels and order or fulfillment status move between Greenplum and Easypost so counts and states agree across reporting and operations.

One customer master

Where both systems keep customer records, corrections in either propagate to the other so analytics and the storefront share one identity.

Live analytics on store activity

Orders, products, and customer records from Easypost land in Greenplum as they change, so dashboards and models read current data instead of last night's export.

What you can sync between Easypost and Greenplum

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 Greenplum objects How this pairing syncs
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. Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Webhook is specific to Easypost and Partitions to Greenplum — 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. Views Read-only projections used to shape data before syncing it out. Shipment is specific to Easypost and Views to Greenplum — 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. External tables Reference external files for bulk load paths alongside row-level syncs. Address is specific to Easypost and External tables to Greenplum — 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. Rows Read and written by key; distribution keys determine where rows live. Parcel is specific to Easypost and Rows to Greenplum — 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. Databases Top-level containers that scope a sync connection. Rate is specific to Easypost and Databases to Greenplum — 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. Schemas Namespace tables and control which objects a sync can see. Tracker is specific to Easypost and Schemas to Greenplum — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Greenplum

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 Greenplum 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 applied to Greenplum as a row-level write, with types converted between the two schemas.

Greenplum Easypost Interval-based propagation

DetectionStacksync polls Greenplum for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key-based cursors.

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.
  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
