Why teams connect IBM AS/400 and Salesforce Marketing Cloud
Give your team Salesforce Marketing Cloud's contacts, campaigns, and engagement in IBM AS/400: query them with SQL, push audiences built from your own data back to Salesforce Marketing Cloud, and skip the marketing API.
Salesforce Marketing Cloud holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in IBM AS/400, hard to get into campaigns without manual exports.
Stacksync mirrors Journeys (Journey Builder), Content Assets (Content Builder), Automations (Automation Studio), Tracking Events from Salesforce Marketing Cloud into Members, Rows / records, Journals and journal receivers, Data queues in IBM AS/400 field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in IBM AS/400, from usage, orders, or account status, sync back into Salesforce Marketing Cloud to drive campaigns and ads, with Salesforce Marketing Cloud kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.
Common use cases
- 01 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
- 02 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
- 03 Two-way sync Data Extension rows between Marketing Cloud and a Postgres database or warehouse so audience attributes and opt-out state stay aligned in both systems.
- 04 Push CRM or warehouse audience segments into Data Extensions via the async rows API (background bulk insert) so marketing sends to freshly built audiences without manual CSV imports.
Common sync patterns
Build audiences from your own data
Segments computed in IBM AS/400 from product usage, orders, or account status sync into Salesforce Marketing Cloud as lists or audiences, so campaigns and ads target the people your data says they should.
Engagement and results next to the customer
Opens, clicks, sends, RSVPs, or ad activity from Salesforce Marketing Cloud land in IBM AS/400 beside the matching customer record, ready for reporting and revenue attribution.
React to marketing changes as row changes
A new lead, form fill, or list change in Salesforce Marketing Cloud arrives as a row change in IBM AS/400, so scoring, jobs, and notifications run in the tooling your team already uses.
What you can sync between IBM AS/400 and Salesforce Marketing Cloud
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 Marketing Cloud objects | How this pairing syncs | |
|---|---|---|---|
| Journals and journal receivers The change log that enables log-based CDC on journaled files. | Transactional Sends Triggered and transactional Email/SMS delivered through the Messaging API (/messaging/v1/email/messages/{key}); the Event Notification Service reports each message's disposition (delivered, bounced, opened, clicked). | Journals and journal receivers is specific to IBM AS/400 and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. | Data Extensions Custom relational tables that store subscriber, audience, and arbitrary business data; rows are read via GET /data/v1/customobjectdata or SOAP Retrieve and upserted via the synchronous rowset PUT or the async /data/v1/async/dataextensions rows endpoint. This is the primary two-way surface. | Data queues is specific to IBM AS/400 and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Libraries The schema-equivalent containers that scope which files a sync reads. | Contacts / Subscribers The contact model keyed by Subscriber Key, holding channel addresses and subscription status; managed through the Contacts API (/contacts/v1/contacts) and the SOAP Subscriber object, and referenced by every send and journey. | Libraries is specific to IBM AS/400 and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Physical files (tables) The Db2 for i tables mapped directly to sync targets. | Journeys (Journey Builder) Multi-step automated flows read and managed via /interaction/v1/interactions; contacts are injected by firing an entry event to /interaction/v1/events with an EventDefinitionKey and contact data. | Physical files (tables) is specific to IBM AS/400 and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Logical files (views) Indexed or filtered views over physical files, usable as read sources. | Content Assets (Content Builder) Emails, templates, images, and reusable content blocks stored in Content Builder and read or written via /asset/v1/content/assets, used to compose the messages a journey or send delivers. | Logical files (views) is specific to IBM AS/400 and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Members Sub-partitions of files in legacy applications, flattened or selected during syncs. | Automations (Automation Studio) Scheduled or triggered workflows of import, query, extract, and send activities managed via /automation/v1/automations; SQL Query Activities read Data Views and write results into Data Extensions. | Members is specific to IBM AS/400 and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. |
How changes propagate between IBM AS/400 and Salesforce Marketing Cloud
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.
IBM AS/400 Salesforce Marketing Cloud Sub-second propagation
DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.
DeliveryEach detected change is written to Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.
Salesforce Marketing Cloud IBM AS/400 Sub-second propagation
DetectionSalesforce Marketing Cloud notifies Stacksync of record changes through webhook events. The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback.
DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
- Salesforce Marketing Cloud: Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.

How the IBM AS/400 and Salesforce Marketing Cloud 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

Salesforce Marketing Cloud
- Integration surface
- Two APIs on tenant-specific endpoints: a REST API (JSON over HTTPS) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, plus a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve.
- Authentication
- OAuth 2.0 via an Installed Package (Client ID + Client Secret). Server-to-server uses the client_credentials grant and web apps use authorization_code, both against {subdomain}.auth.marketingcloudapis.com/v2/token. The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url.
- Change detection
- The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback URL and subscription are registered and verified. There is no general data-change feed, so Data Extension and Data View syncs poll by date fields.
- Capabilities
- read · write · webhooks
- Rate limits
- Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.

FAQ
IBM AS/400 and Salesforce Marketing Cloud integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between IBM AS/400 and Salesforce Marketing Cloud: authenticate both systems, choose the objects to sync (such as IBM AS/400's Journals and journal receivers and Data queues), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the IBM AS/400 side: Members, Rows / records, Journals and journal receivers, Data queues, plus custom fields where IBM AS/400 exposes them. On the Salesforce Marketing Cloud side: Journeys (Journey Builder), Content Assets (Content Builder), Automations (Automation Studio), Tracking Events. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for IBM AS/400 and Salesforce Marketing Cloud: Build audiences from your own data; Engagement and results next to the customer; React to marketing changes as row changes. Segments computed in IBM AS/400 from product usage, orders, or account status sync into Salesforce Marketing Cloud as lists or audiences, so campaigns and ads target the people your data says they should.

The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url. Stacksync manages authentication, retries, and rate limits on both sides.
-
IBM AS/400: The integrated database is Db2 for i; tables are physical files organized into libraries, with logical files acting as views. Salesforce Marketing Cloud: Marketing Cloud uses tenant-specific endpoints; OAuth v2 tokens come from an Installed Package's Client ID/Secret at {subdomain}.auth.marketingcloudapis.com/v2/token and expire after 20 minutes. Stacksync's field mapping accounts for these differences between IBM AS/400 and Salesforce Marketing Cloud without custom code.
