Why teams connect Easypost and MongoDB

Give your engineers Easypost's products, orders, and customers in MongoDB: 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 Parcel, Rate, Tracker, Batch from Easypost into MongoDB 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 MongoDB, 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 Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
  • 02 Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
  • 03 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.
  • 04 Batch-create and buy labels for a day's orders, generate a ScanForm, and write each label and tracking code back into the fulfillment system.

Common sync patterns

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Easypost API, rate limits, and retries.

React to store changes

Updates in Easypost arrive as row changes in MongoDB, so jobs and triggers can respond the moment an order, price, or stock level changes.

Keep catalog and inventory current

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

What you can sync between Easypost and MongoDB

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 MongoDB objects How this pairing syncs
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Collections The table-like sync unit; each collection maps to a table or object in the paired system. Parcel is specific to Easypost and Collections to MongoDB — 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. Documents BSON records created, updated, and deleted during syncs, keyed by _id. Rate is specific to Easypost and Documents to MongoDB — 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. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Tracker is specific to Easypost and Embedded documents and arrays to MongoDB — 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. Indexes Keep lookups by sync key fast on large collections. Batch is specific to Easypost and Indexes to MongoDB — 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. Views Read-only aggregation-defined sources for filtered sync datasets. CarrierAccount is specific to Easypost and Views to MongoDB — 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. Change streams The oplog-backed event feed that powers real-time change capture. Webhook is specific to Easypost and Change streams to MongoDB — each maps to any object or custom field on the other side.

How changes propagate between Easypost and MongoDB

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

MongoDB Easypost Sub-second propagation

DetectionChanges in MongoDB are captured at the source via change data capture — no polling loop against its API. MongoDB oplog and change streams (requires the database to run as a replica set — even single-node).

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.
