Why teams connect IBM AS/400 and Smartrecruiters

Put your workforce data where your apps can reach it: IBM AS/400 and Smartrecruiters share the same people, positions, and org structure in real time.

Smartrecruiters is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. IBM AS/400 is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Applications, Jobs, Job Postings, Interviews in Smartrecruiters need to exist as queryable Data queues, Libraries, Physical files (tables), Logical files (views) in IBM AS/400 before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Data queues, Libraries, Physical files (tables), Logical files (views) in IBM AS/400 with Applications, Jobs, Job Postings, Interviews in Smartrecruiters field by field, in real time. You decide which system owns which fields — Smartrecruiters typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • 02 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 03 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.
  • 04 Subscribe to the Webhooks API to react to new applications and status changes in near real time across downstream systems.

Common sync patterns

Mirror people records into the database

Records maintained in Smartrecruiters land as queryable Data queues, Libraries, Physical files (tables), Logical files (views) in IBM AS/400, so internal apps and dashboards read live data instead of a periodic export.

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Applications, Jobs, Job Postings, Interviews replicate into IBM AS/400 where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between IBM AS/400 and Smartrecruiters

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 Smartrecruiters objects How this pairing syncs
Journals and journal receivers The change log that enables log-based CDC on journaled files. Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. Journals and journal receivers is specific to IBM AS/400 and Jobs to Smartrecruiters — 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. Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). Data queues is specific to IBM AS/400 and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Libraries The schema-equivalent containers that scope which files a sync reads. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Libraries is specific to IBM AS/400 and Interviews to Smartrecruiters — 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. Offers Offer records tied to an Application with status, custom offer fields, and offer documents; readable and writable, commonly synced to an HRIS on hire (documents endpoint limited to 2 requests/sec). Physical files (tables) is specific to IBM AS/400 and Offers to Smartrecruiters — 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. Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. Logical files (views) is specific to IBM AS/400 and Users to Smartrecruiters — 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. Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Members is specific to IBM AS/400 and Approvals to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between IBM AS/400 and Smartrecruiters

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 Smartrecruiters 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 Smartrecruiters through its API, with automatic retries and rate-limit backoff.

Smartrecruiters IBM AS/400 Sub-second propagation

DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.

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.
  • Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.
