Why teams connect PostgreSQL and Shipwire

Give your engineers Shipwire's products, orders, and customers in PostgreSQL: 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 Trackings, Rates, Orders, Products from Shipwire into PostgreSQL and keeps both sides consistent in real time. Whatever Shipwire holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in PostgreSQL, such as new prices, stock levels, or fulfillment status, sync back into Shipwire 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 Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • 02 Let an application write to its own database and have those rows appear as records in business systems in near real time
  • 03 Pull Returns and tracking.delivered events into a support or analytics database for reverse-logistics and delivery-SLA reporting.
  • 04 Two-way sync Orders between a storefront or ERP database and Shipwire so new orders create fulfillment requests and Stacksync writes Trackings and status (processed, submitted, delivered) back.

Common sync patterns

Internal tools and automations without API code

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

React to store changes

Updates in Shipwire arrive as row changes in PostgreSQL, 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 PostgreSQL sync back onto Shipwire, so the storefront shows what your systems treat as true.

What you can sync between PostgreSQL and Shipwire

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.

PostgreSQL objects Shipwire objects How this pairing syncs
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Returns Return orders raised against existing Orders; created via API and read back into support or analytics systems for reverse-logistics tracking. Tables is specific to PostgreSQL and Returns to Shipwire — each maps to any object or custom field on the other side.
Views Read-side projections used to expose joined or filtered data to a sync. Purchase Orders B2B orders with retailer-specific routing and compliance fields; managed via API alongside receivings for wholesale and marketplace fulfillment. Views is specific to PostgreSQL and Purchase Orders to Shipwire — each maps to any object or custom field on the other side.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Trackings Shipment tracking numbers and carrier status returned as an Order subresource and surfaced through tracking.created, tracking.updated, and tracking.delivered webhook topics. Materialized Views is specific to PostgreSQL and Trackings to Shipwire — each maps to any object or custom field on the other side.
Schemas Namespaces that scope which tables a sync reads and writes. Rates Shipping cost quotes for a cart or order; read-only, called at checkout time to estimate carrier costs rather than synced as stored records. Schemas is specific to PostgreSQL and Rates to Shipwire — each maps to any object or custom field on the other side.
Columns Field-level mapping targets; types are mapped to the connected system's field types. Orders B2C fulfillment orders (create, update, cancel, get) with item, hold, routing, and tracking subresources; typically written from a storefront or ERP and synced back with status and trackings. Columns is specific to PostgreSQL and Orders to Shipwire — each maps to any object or custom field on the other side.
Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Products Catalog SKUs including kits, virtual kits, and marketplace products; created and edited via API, commonly mastered in a PIM or ERP and pushed into Shipwire with dimensions and pricing. Primary and Unique Keys is specific to PostgreSQL and Products to Shipwire — each maps to any object or custom field on the other side.

How changes propagate between PostgreSQL and Shipwire

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.

PostgreSQL Shipwire Sub-second propagation

DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.

DeliveryEach detected change is written to Shipwire through its API, with automatic retries and rate-limit backoff.

Shipwire PostgreSQL Sub-second propagation

DetectionShipwire notifies Stacksync of record changes through webhook events. Webhooks (HMAC-SHA256 signed, near real-time) on order, tracking, stock, receiving, return, and product topics.

DeliveryEach detected change is applied to PostgreSQL as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.
  • Shipwire: No published per-second request cap; list responses page at 20 items (recommended max ~200) and webhook payloads carry at most 20 items per resource, so large records must be paged via the response next links.
