Why teams connect AWS S3 and Linnworks

Put Linnworks's records in AWS S3 as live tables for reporting and analysis, without extract jobs, and write results back where Linnworks can use them.

ERP data is some of the most asked-for data in the warehouse and some of the hardest to get: the record types are many, the APIs are strict, and extract jobs are brittle. Whether Linnworks carries financials, operations, workforce data, or all three, the analysis belongs in AWS S3 next to everything else the company measures.

Stacksync syncs Suppliers, Channel Listings, Returns & Refunds, Shipping Services from Linnworks into tables in AWS S3 continuously, managing API limits and schema drift along the way. The connection is bi-directional, so values computed in AWS S3 can be written back to fields in Linnworks where that is useful.

Common use cases

  • Trigger incremental sync runs from S3 event notifications when new files land in a prefix.
  • Stage bulk loads for warehouses that ingest from object storage.
  • Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • Push customer and order data to a CRM or marketing platform for post-purchase campaigns

Group reporting across systems

Combine Linnworks's records with data synced from other systems in AWS S3 for consolidated views no single system can produce.

Write-back where Linnworks exposes writable fields

Classifications or reference values computed in AWS S3 sync back onto the corresponding records in Linnworks.

Where Linnworks holds the books: finance reporting from live data

Financial records land in AWS S3 as they change, so period-end reporting queries current numbers rather than last night's extract.

What you can sync between AWS S3 and Linnworks

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.

AWS S3 objects Linnworks objects
Buckets Top-level containers a sync targets; region and policy are set at this level. Returns & Refunds Post-sale records flow to finance and support systems.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Shipping Services Carrier and service definitions support label and tracking data in order syncs.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems.
Object Metadata System and user-defined metadata read alongside object contents. Processed Orders Completed orders feed accounting and warehouse-based margin reporting.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Stock Items SKU records keep product data aligned with ERPs and PIMs.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability.
