Why teams connect IBM AS/400 and Salesforce

Treat Salesforce 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 Opportunities, Cases, Campaigns, Tasks and Events from Salesforce into Data queues, Libraries, Physical files (tables), Logical files (views) 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 Salesforce 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

  • Consolidate multiple Salesforce orgs into a single database for cross-org reporting after an acquisition.
  • Sync Accounts, Contacts, and Opportunities bi-directionally with Postgres so engineering teams read and write CRM data with plain SQL.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

Query the CRM like a database

Accounts, contacts, and custom objects from Salesforce 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 Salesforce, 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 Salesforce API, limits, and retries.

What you can sync between IBM AS/400 and Salesforce

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 Salesforce objects
Journals and journal receivers The change log that enables log-based CDC on journaled files. Tasks and Events Activity records; usually read-only in syncs to feed activity reporting.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce.
Libraries The schema-equivalent containers that scope which files a sync reads. Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines.

How the IBM AS/400 and Salesforce 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.

Salesforce

Integration surface
REST, SOAP, and Bulk APIs
Authentication
OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode
Change detection
Apex triggers are used whenever possible (Salesforce actively notifies Stacksync via an Apex trigger + callout class + remote site setting)
Capabilities
read · write · CDC
Rate limits
Daily API request allocations vary by edition and license count.
