Why teams connect Firebase and Shopware
Give your engineers Shopware's products, orders, and customers in Firebase: 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 Products, Categories, Customers, Orders from Shopware into Firebase 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 Firebase, 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 Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
- 02 Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.
- 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 Firebase, 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 Firebase sync back onto Shopware, so the storefront shows what your systems treat as true.
What you can sync between Firebase 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.
| Firebase objects | Shopware objects | How this pairing syncs | |
|---|---|---|---|
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Orders Order headers (`order`) with totals, state, and sales-channel reference; read out to accounting and written back for status updates. | Cloud Functions Triggers is specific to Firebase and Orders to Shopware — each maps to any object or custom field on the other side. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Order Line Items Per-order product rows (`order_line_item`); read alongside the order for revenue and fulfillment reporting. | Firestore Collections is specific to Firebase and Order Line Items to Shopware — each maps to any object or custom field on the other side. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Order Deliveries Shipping records (`order_delivery`) carrying delivery state and tracking codes; written back from a 3PL or WMS. | Firestore Documents is specific to Firebase and Order Deliveries to Shopware — each maps to any object or custom field on the other side. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Order Transactions Payment records (`order_transaction`) holding payment method and state; read to reconcile against a billing or finance system. | Subcollections is specific to Firebase and Order Transactions to Shopware — each maps to any object or custom field on the other side. | |
| Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Sales Channels Per-storefront configuration (`sales_channel`); used to scope and consolidate orders and customers across multiple storefronts. | Realtime Database Nodes is specific to Firebase and Sales Channels to Shopware — each maps to any object or custom field on the other side. | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Media Media assets (`media`) such as product images; referenced by id so file URLs and metadata sync into downstream catalogs. | Authentication Users is specific to Firebase and Media to Shopware — each maps to any object or custom field on the other side. |
How changes propagate between Firebase 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.
Firebase Shopware Interval-based propagation
DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.
DeliveryEach detected change is written to Shopware through its API, with automatic retries and rate-limit backoff.
Shopware Firebase 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 written to Firebase through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.
- 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.

FAQ
Firebase and Shopware integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Shopware: authenticate both systems, choose the objects to sync (such as Firebase's Cloud Functions Triggers and Firestore Collections), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Firebase: REST and gRPC APIs, typically accessed through the Firebase Admin SDK. Authentication: Google service account credentials (IAM) for server-side access; Firebase Auth tokens for client contexts. Shopware: Admin API (REST / JSON:API) with a bulk POST /api/_action/sync endpoint. Authentication: OAuth 2.0 — client-credentials grant using an Integration's Access Key ID + Secret Access Key, or resource-owner password grant for a user; access tokens expire after 10 minutes. Stacksync manages authentication, retries, and rate limits on both sides.
-
Firebase: Firestore documents are schemaless and support nested maps and arrays, so syncs define field mappings per document path rather than from a fixed schema. Shopware: Bulk writes go through POST /api/_action/sync, which upserts and deletes many entities in a single request. Stacksync's field mapping accounts for these differences between Firebase and Shopware 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 Firebase and Shopware records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Shopware connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Shopware integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Shopware. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
