Why teams connect PostgreSQL and Shopify

Treat Shopify like part of your database: its records live in PostgreSQL as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in PostgreSQL, where it can be queried and joined like everything else.

Stacksync mirrors Customers, Abandoned Checkouts, Products, ProductMedias from Shopify into Custom Types and Enums, Tables, Views, Materialized Views in PostgreSQL with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Shopify with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Sync orders, customers, and inventory into Postgres for operational reporting across stores.
  • Keep customer records aligned between Shopify and a CRM for segmentation and lifetime-value analysis.
  • Consolidate data from several microservice databases into one operational Postgres store
  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Shopify API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Shopify arrive as row changes in PostgreSQL, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Shopify become tables in PostgreSQL you can join with application data directly.

What you can sync between PostgreSQL and Shopify

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.

PostgreSQL objects Shopify objects
Columns Field-level mapping targets; types are mapped to the connected system's field types. Orders Purchase transactions; pushed to ERPs for fulfillment and billing, and read into databases for reporting.
Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Customers Buyer records; matched to CRM contacts for marketing and lifetime-value analysis.
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Abandoned Checkouts Synced with incremental and full sync per the Stacksync docs.
Sequences Generate surrogate keys for rows created by inbound syncs. Products Catalog entries; often mastered in a PIM or ERP and written into Shopify.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. ProductMedias Synced with incremental and full sync per the Stacksync docs.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. ProductVariants Synced with incremental and full sync per the Stacksync docs.
What ships with PostgreSQL ⇄ Shopify

Connect PostgreSQL and Shopify for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every PostgreSQL–Shopify connection.

Real-time

Two-way sync

Changes in PostgreSQL or Shopify instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever PostgreSQL or Shopify data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single PostgreSQL or Shopify record.

Observability

Monitoring

Track your PostgreSQL ⇄ Shopify sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between PostgreSQL and Shopify.

How the PostgreSQL and Shopify connectors work

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput
PostgreSQL setup guide

Shopify

Integration surface
GraphQL Admin API (primary) and REST Admin API (legacy)
Authentication
OAuth via a custom Shopify app: admin creates an app in the Shopify Dev Dashboard, enables required API scopes, sets the Stacksync redirect URL, then supplies shop name + Client ID and Client Secret to Stacksync
Change detection
Webhook topics per resource, with polling on updated_at as a fallback
Capabilities
read · write · webhooks
Rate limits
GraphQL uses a calculated query-cost budget; the REST API uses a leaky-bucket model.

How it works

How to connect PostgreSQL to Shopify — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate PostgreSQL and Shopify with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the PostgreSQL and Shopify objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
