Why teams connect Easypost and Render Postgres
Give your engineers Easypost's products, orders, and customers in Render Postgres: 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 Address, Parcel, Rate, Tracker from Easypost into Render Postgres 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 Render Postgres, 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 Replicate between a Render database and another Postgres or warehouse for migration or environment separation.
- 02 Two-way sync CRM or ERP objects into Render Postgres tables so product and ops teams query business data with plain SQL.
- 03 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.
- 04 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.
Common sync patterns
React to store changes
Updates in Easypost arrive as row changes in Render Postgres, 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 Render Postgres 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 Render Postgres for routing, fulfillment, and reporting, without polling the platform.
What you can sync between Easypost and Render Postgres
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 | Render Postgres objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Materialized Views Precomputed query results refreshed on demand; read for fast reporting tables that downstream systems can consume. | Shipment is specific to Easypost and Materialized Views to Render Postgres — 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. | Schemas Namespaces that organize tables per app or environment; sync targets are scoped per schema to keep synced data isolated and tidy. | Address is specific to Easypost and Schemas to Render Postgres — 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. | Columns and Types Full Postgres type system including JSONB and arrays; field mappings preserve native types instead of flattening to strings. | Parcel is specific to Easypost and Columns and Types to Render Postgres — 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. | Indexes and Constraints Primary keys, unique constraints, and foreign keys; unique keys drive idempotent upserts and conflict resolution during sync. | Rate is specific to Easypost and Indexes and Constraints to Render Postgres — 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. | Tables Relational tables with full column typing; synced two-way with CRMs, ERPs, and SaaS apps so application data is queryable as plain Postgres rows. | Tracker is specific to Easypost and Tables to Render Postgres — 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. | Views Saved queries exposed as read-only relations; read out to BI tools or downstream syncs without duplicating transformation logic. | Batch is specific to Easypost and Views to Render Postgres — each maps to any object or custom field on the other side. |
How changes propagate between Easypost and Render Postgres
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 Render Postgres 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 Render Postgres as a row-level write, with types converted between the two schemas.
Render Postgres Easypost Sub-second propagation
DetectionChanges in Render Postgres are captured at the source via change data capture — no polling loop against its API. Logical replication via WAL and replication slots for change data capture when enabled on the instance, with timestamp or cursor-based polling as the.
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.
- Render Postgres: No API rate limits — throughput is bounded by the instance's plan (CPU, RAM, connection limit); connection pooling is recommended since managed plans cap concurrent connections.

FAQ
Easypost and Render Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Easypost and Render Postgres: authenticate both systems, choose the objects to sync (such as Easypost's Shipment and Address), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Easypost and Render Postgres: React to store changes; Keep catalog and inventory current; Order data where your code can use it. Updates in Easypost arrive as row changes in Render Postgres, so jobs and triggers can respond the moment an order, price, or stock level changes.
-
Easypost: REST API (EasyPost API v2, https://api.easypost.com/v2). Authentication: HTTP Basic auth with the API key as the username and an empty password (Bearer token also accepted); separate Test and Production keys. Render Postgres: PostgreSQL wire protocol (managed Postgres on Render). Authentication: Standard Postgres connection string — host, port, database, user, password with TLS; Render provides internal and external connection URLs and IP allowlisting. Stacksync manages authentication, retries, and rate limits on both sides.
-
Render Postgres: External connections use a separate hostname from Render-internal ones and require TLS; access can be restricted by IP allowlist. Easypost: Rates are generated by EasyPost, not written - you create a Shipment, receive a set of Rate options, then buy against the chosen rate id, and the label (postage_label) and tracking_code come back on the purchased Shipment. Stacksync's field mapping accounts for these differences between Easypost and Render Postgres without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Easypost and Render Postgres records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Easypost and Render Postgres connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Easypost–Render Postgres integration in-house.
