Why teams connect Demandbase and IBM AS/400

Give your team Demandbase's contacts, campaigns, and engagement in IBM AS/400: query them with SQL, push audiences built from your own data back to Demandbase, and skip the marketing API.

Demandbase 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 Campaigns, Account & Person Lists (Audiences), Company Details (B2B enrichment), Change Subscriptions from Demandbase 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 Demandbase to drive campaigns and ads, with Demandbase kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 02 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • 03 Push warehouse-computed account scores, custom fields, and audiences into Demandbase via the Data Import API so ABM campaigns and sales plays target the segments the warehouse defines.
  • 04 Enrich CRM Company and Contact records with Demandbase firmographics, technographics, and verified business emails through the B2B Company and Contact Details endpoints.

Common sync patterns

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Demandbase 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 Demandbase arrives as a row change in IBM AS/400, so scoring, jobs, and notifications run in the tooling your team already uses.

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

What you can sync between Demandbase and IBM AS/400

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.

Demandbase objects IBM AS/400 objects How this pairing syncs
Change Subscriptions Company firmographic, company news, family-tree (ownership), and DB person employment subscriptions delivered as webhook alerts with a signing secret; the real-time change feed. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Change Subscriptions is specific to Demandbase and Members to IBM AS/400 — each maps to any object or custom field on the other side.
Accounts Company/account records with firmographics, intent, and Demandbase qualification and engagement scores; exported via the Data Export API and imported or updated via the Data Import API. Rows / records The unit of read and write, accessed via SQL or record-level access. Accounts is specific to Demandbase and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.
Opportunities Opportunity records synced from the CRM into Demandbase; exported with calculated insights and imported or updated through the Data Import API. Read and write. Journals and journal receivers The change log that enables log-based CDC on journaled files. Opportunities is specific to Demandbase and Journals and journal receivers to IBM AS/400 — each maps to any object or custom field on the other side.
People (Persons) Contact/person records with verified business email, title, seniority, and quality grades; fetched and matched via the B2B Contact endpoints and exported or imported. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. People (Persons) is specific to Demandbase and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.
Activities Engagement and custom activity records (web, campaign, intent); exported via Data Export and pushed in through the Data Import API using custom activity types. Libraries The schema-equivalent containers that scope which files a sync reads. Activities is specific to Demandbase and Libraries to IBM AS/400 — each maps to any object or custom field on the other side.
Campaigns Marketing campaign records and creative assets exported through the Data Export API; read-only reporting feed. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Campaigns is specific to Demandbase and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Demandbase and IBM AS/400

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.

Demandbase IBM AS/400 Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 Demandbase 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 Demandbase through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.

How the Demandbase and IBM AS/400 connectors work

Demandbase

Integration surface
REST APIs (Demandbase One) - a B2B API (company/contact search, details, and match with async bulk enrichment jobs), a read-only Data Export API and a write-capable Data Import API (both async bulk jobs), and a Subscription API for webhook change alerts.
Authentication
JWT bearer tokens minted from Demandbase One API Key Sets at the platform level; each credential set expires after 8 hours and is rotated. Legacy single-user API tokens are deprecated.
Change detection
Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL secured with a signing secret; bulk reads run as async export jobs (submit, poll, download). No log-based CDC.
