Why teams connect Amazon Seller Central and Postgres Heroku

Mirror Amazon Seller Central's data into Postgres Heroku 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 Postgres Heroku, so Postgres Heroku 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 Postgres Heroku.

Stacksync mirrors Shipments, Financial Events, Returns, Reports from Amazon Seller Central into Materialized Views, Schemas, Primary and Unique Keys, JSONB Columns in Postgres Heroku 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

  • Land Amazon orders, reports, and settlement data in your warehouse or ERP as they are produced.
  • Track price and inventory report changes across marketplaces from one queryable table.
  • Sync Heroku Postgres into a warehouse for reporting without running ETL dynos
  • Keep several Heroku app databases aligned with one system of record

Automate Amazon Seller Central from your codebase

Write to the synced tables in Postgres Heroku and Stacksync propagates the change into Amazon Seller Central, replacing custom integration code.

React to changes as they happen

Updates in Amazon Seller Central arrive as row changes in Postgres Heroku, 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.

What you can sync between Amazon Seller Central and Postgres Heroku

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 Postgres Heroku objects
Listings / Catalog Items Product listing content and status, readable and updatable through the Listings and Feeds APIs. JSONB Columns Semi-structured payloads for nested SaaS objects and metadata.
FBA Inventory Fulfillable quantity by SKU, synced out for stock planning and replenishment. Sequences Generate surrogate keys for rows created by inbound syncs.
Shipments Inbound and outbound shipment records used to track fulfillment state. Follower Databases Heroku-managed read replicas usable as low-impact sync sources.
Financial Events Settlement, fee, and refund events synced to finance systems for reconciliation. Tables Standard Postgres tables; the primary two-way sync target for app data.
Returns Return and refund records routed to support and finance workflows. Views Read-side projections exposed to outbound syncs.
Reports Asynchronous bulk exports used for large reads (orders, inventory, settlements). Materialized Views Precomputed result sets synced outward on refresh.

How the Amazon Seller Central and Postgres Heroku connectors work

Amazon Seller Central

Integration surface
REST API (Selling Partner API, SP-API)
Authentication
SP-API app credentials (LWA client ID/secret, application ID, Merchant ID/Seller ID token, refresh token, region) entered into the Stacksync connection form
Change detection
Historical and incremental syncs (mechanism not further specified)
Capabilities

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
Authentication
Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection
Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
