Why teams connect Amazon Seller Central and Citus

Mirror Amazon Seller Central's data into Citus so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Amazon Seller Central is a read-only source: Stacksync reads its data in real time and delivers it into Citus, so Citus always reflects the current state of Amazon Seller Central — without exports, scripts, or schedulers.

Engineers integrate with tools like Amazon Seller Central through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Citus.

Stacksync mirrors Listings / Catalog Items, FBA Inventory, Shipments, Financial Events from Amazon Seller Central into Reference tables, Local tables, Schemas, Views in Citus and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Amazon Seller Central, so the tool and the database never disagree.

Common use cases

  • 01 Track price and inventory report changes across marketplaces from one queryable table.
  • 02 Land Amazon orders, reports, and settlement data in your warehouse or ERP as they are produced.
  • 03 Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • 04 Consolidate per-tenant rows from distributed tables into per-customer reporting databases.

Common sync patterns

React to changes as they happen

Updates in Amazon Seller Central arrive as row changes in Citus, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Amazon Seller Central with a query

Records from Amazon Seller Central are ordinary rows in Citus; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Amazon Seller Central and Citus

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.

Amazon Seller Central objects Citus objects How this pairing syncs
Order Items Line-level SKU, quantity, and price data joined to orders in downstream systems. Views Curated projections over distributed data, often used as read-only sync sources. Order Items is specific to Amazon Seller Central and Views to Citus — each maps to any object or custom field on the other side.
Listings / Catalog Items Product listing content and status, readable and updatable through the Listings and Feeds APIs. Sequences Key generators that matter when external writes must not collide with application inserts. Listings / Catalog Items is specific to Amazon Seller Central and Sequences to Citus — each maps to any object or custom field on the other side.
FBA Inventory Fulfillable quantity by SKU, synced out for stock planning and replenishment. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. FBA Inventory is specific to Amazon Seller Central and Distributed tables to Citus — each maps to any object or custom field on the other side.
Shipments Inbound and outbound shipment records used to track fulfillment state. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Shipments is specific to Amazon Seller Central and Reference tables to Citus — each maps to any object or custom field on the other side.
Financial Events Settlement, fee, and refund events synced to finance systems for reconciliation. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Financial Events is specific to Amazon Seller Central and Local tables to Citus — each maps to any object or custom field on the other side.
Returns Return and refund records routed to support and finance workflows. Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Returns is specific to Amazon Seller Central and Schemas to Citus — each maps to any object or custom field on the other side.

How changes propagate between Amazon Seller Central and Citus

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.

Amazon Seller Central Citus Interval-based propagation

DetectionStacksync polls Amazon Seller Central for changes on an incremental schedule, reading only records changed since the previous pass. Historical and incremental syncs (mechanism not further specified).

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

Citus Amazon Seller Central Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

DeliveryAmazon Seller Central does not accept inbound record writes, so this direction carries requests rather than records: Amazon Seller Central's output flows back as field updates on the originating Citus records.

Rate-limit considerations

  • Amazon Seller Central: Per-operation token-bucket rate limits; bulk reads and writes should go through the asynchronous Reports and Feeds APIs instead of item-by-item calls.
