Why teams connect Easypost and Snowflake

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

Snowflake 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 Materialized Views, Streams, Stages, Tasks in Snowflake with CarrierAccount, Webhook, Shipment, Address 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 Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • 02 Push product usage aggregates from Snowflake into sales and success tools for account prioritization
  • 03 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 04 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.

Common sync patterns

Live analytics on store activity

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

Where Easypost accepts writes: push computed attributes back

Segments, lifetime value, and scores built in Snowflake write onto the matching records in Easypost, so merchandising and messaging act on warehouse logic.

One product catalog

Where both systems hold product or catalog data, cleaned and enriched attributes stay aligned so the store and the warehouse describe the same items.

What you can sync between Easypost and Snowflake

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 Snowflake 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. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns. Batch is specific to Easypost and VARIANT Columns to Snowflake — 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. Virtual Warehouses The compute a sync's queries run on, sized independently of storage. CarrierAccount is specific to Easypost and Virtual Warehouses to Snowflake — 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. Databases Top-level containers that scope which data a sync can touch. Webhook is specific to Easypost and Databases to Snowflake — 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. Schemas Namespaces within a database used to organize synced tables. Shipment is specific to Easypost and Schemas to Snowflake — 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. Tables The main landing and activation target for synced records. Address is specific to Easypost and Tables to Snowflake — 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. Views Modeled projections used as the source side of outbound syncs. Parcel is specific to Easypost and Views to Snowflake — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Snowflake

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 Snowflake 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 Snowflake as a row-level write, with types converted between the two schemas.

Snowflake Easypost Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

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.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
