Why teams connect Google Cloud SQL and Shopware

Give your engineers Shopware's products, orders, and customers in Google Cloud SQL: 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 Transactions, Sales Channels, Media, Products from Shopware into Google Cloud SQL 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 Google Cloud SQL, 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 an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • 02 Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.
  • 03 Write tracking numbers and delivery state onto `order_delivery` from a 3PL or WMS so storefront order status reflects fulfillment.
  • 04 Consolidate orders and customers from multiple `sales_channel` storefronts into one Postgres database for cross-channel analysis.

Common sync patterns

Internal tools and automations without API code

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

React to store changes

Updates in Shopware arrive as row changes in Google Cloud SQL, 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 Google Cloud SQL sync back onto Shopware, so the storefront shows what your systems treat as true.

What you can sync between Google Cloud SQL 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.

Google Cloud SQL objects Shopware objects How this pairing syncs
Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to. Order Transactions Payment records (`order_transaction`) holding payment method and state; read to reconcile against a billing or finance system. Instances is specific to Google Cloud SQL and Order Transactions to Shopware — each maps to any object or custom field on the other side.
Databases Scope the tables included in a sync configuration. Sales Channels Per-storefront configuration (`sales_channel`); used to scope and consolidate orders and customers across multiple storefronts. Databases is specific to Google Cloud SQL and Sales Channels to Shopware — each maps to any object or custom field on the other side.
Schemas Namespace tables in PostgreSQL and SQL Server instances. Media Media assets (`media`) such as product images; referenced by id so file URLs and metadata sync into downstream catalogs. Schemas is specific to Google Cloud SQL and Media to Shopware — each maps to any object or custom field on the other side.
Tables Mapped directly to sync targets; schema changes can be propagated. 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. Tables is specific to Google Cloud SQL and Products to Shopware — each maps to any object or custom field on the other side.
Rows Read and written by primary key during each sync cycle. Categories The navigation and catalogue tree (`category`); mapped to product taxonomy in a warehouse or written from a PIM. Rows is specific to Google Cloud SQL and Categories to Shopware — each maps to any object or custom field on the other side.
Views Read-only sources for shaping data before syncing it out. Customers Storefront customer accounts (`customer`) with addresses and group; synced two-way with a CRM or support tool. Views is specific to Google Cloud SQL and Customers to Shopware — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud SQL 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.

Google Cloud SQL Shopware Sub-second propagation

DetectionChanges in Google Cloud SQL are captured at the source via change data capture — no polling loop against its API. Engine-dependent log-based CDC: MySQL binlog, PostgreSQL logical replication, SQL Server change tracking.

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

Shopware Google Cloud SQL 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 Google Cloud SQL as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud SQL: Constrained by instance size and connection limits rather than API quotas.
  • 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.
