Why teams connect Postgres Heroku and Shopware

Give your engineers Shopware's products, orders, and customers in Postgres Heroku: 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 Order Deliveries, Order Transactions, Sales Channels, Media from Shopware into Postgres Heroku and keeps both sides consistent in real time. Whatever Shopware holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in Postgres Heroku, such as new prices, stock levels, or fulfillment status, sync back into Shopware 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 Keep several Heroku app databases aligned with one system of record
  • 02 Reflect billing and subscription records into the app database so product logic reads local rows
  • 03 Consolidate orders and customers from multiple `sales_channel` storefronts into one Postgres database for cross-channel analysis.
  • 04 Two-way sync of the `product` catalog — titles, nested price arrays, and stock — between Shopware and an ERP or PIM so pricing and inventory stay aligned.

Common sync patterns

React to store changes

Updates in Shopware arrive as row changes in Postgres Heroku, 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 Postgres Heroku sync back onto Shopware, 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 Postgres Heroku for routing, fulfillment, and reporting, without polling the platform.

What you can sync between Postgres Heroku and Shopware

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.

Postgres Heroku objects Shopware objects How this pairing syncs
Tables Standard Postgres tables; the primary two-way sync target for app data. Order Deliveries Shipping records (`order_delivery`) carrying delivery state and tracking codes; written back from a 3PL or WMS. Tables is specific to Postgres Heroku and Order Deliveries to Shopware — each maps to any object or custom field on the other side.
Views Read-side projections exposed to outbound syncs. Order Transactions Payment records (`order_transaction`) holding payment method and state; read to reconcile against a billing or finance system. Views is specific to Postgres Heroku and Order Transactions to Shopware — each maps to any object or custom field on the other side.
Materialized Views Precomputed result sets synced outward on refresh. Sales Channels Per-storefront configuration (`sales_channel`); used to scope and consolidate orders and customers across multiple storefronts. Materialized Views is specific to Postgres Heroku and Sales Channels to Shopware — each maps to any object or custom field on the other side.
Schemas Namespaces that scope which tables a sync reads and writes. Media Media assets (`media`) such as product images; referenced by id so file URLs and metadata sync into downstream catalogs. Schemas is specific to Postgres Heroku and Media to Shopware — each maps to any object or custom field on the other side.
Primary and Unique Keys Match keys for idempotent upserts from connected systems. Products The product catalog (`product`), including parent/child variants, per-currency nested price arrays, and stock; synced two-way with ERP, PIM, or a database. Primary and Unique Keys is specific to Postgres Heroku and Products to Shopware — each maps to any object or custom field on the other side.
JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. Categories The navigation and catalogue tree (`category`); mapped to product taxonomy in a warehouse or written from a PIM. JSONB Columns is specific to Postgres Heroku and Categories to Shopware — each maps to any object or custom field on the other side.

How changes propagate between Postgres Heroku and Shopware

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.

Postgres Heroku Shopware Interval-based propagation

DetectionStacksync polls Postgres Heroku for changes on an incremental schedule, reading only records changed since the previous pass. Trigger-based capture or polling in most configurations.

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

Shopware Postgres Heroku Sub-second propagation

DetectionShopware notifies Stacksync of record changes through webhook events. App-system webhooks on entity events (product.written, order.written, customer.written) deliver the changed record's primaryKey and updated field.

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

Rate-limit considerations

  • Postgres Heroku: No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan.
  • Shopware: No general throttle on Admin API entity endpoints; Shopware's RateLimiter guards only specific routes (login, oauth, password reset, guest order/contact) and is configurable on self-hosted stores.
