Why teams connect IBM AS/400 and Shopify

Treat Shopify like part of your database: its records live in IBM AS/400 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 IBM AS/400, where it can be queried and joined like everything else.

Stacksync mirrors Abandoned Checkouts, Products, ProductMedias, ProductVariants from Shopify into Journals and journal receivers, Data queues, Libraries, Physical files (tables) in IBM AS/400 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.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

Query the CRM like a database

Accounts, contacts, and custom objects from Shopify become tables in IBM AS/400 you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to IBM AS/400 sync onto the matching records in Shopify, giving go-to-market teams live product context.

Internal tools without API code

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

What you can sync between IBM AS/400 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.

IBM AS/400 objects Shopify objects
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. ProductMedias Synced with incremental and full sync per the Stacksync docs.
Rows / records The unit of read and write, accessed via SQL or record-level access. ProductVariants Synced with incremental and full sync per the Stacksync docs.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Orders Purchase transactions; pushed to ERPs for fulfillment and billing, and read into databases for reporting.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Customers Buyer records; matched to CRM contacts for marketing and lifetime-value analysis.
Libraries The schema-equivalent containers that scope which files a sync reads. Abandoned Checkouts Synced with incremental and full sync per the Stacksync docs.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Products Catalog entries; often mastered in a PIM or ERP and written into Shopify.

How the IBM AS/400 and Shopify connectors work

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

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.
