Why teams connect InterSystems IRIS and Smartrecruiters

Put your workforce data where your apps can reach it: InterSystems IRIS 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. InterSystems IRIS is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Approvals, Candidates, Applications, Jobs in Smartrecruiters need to exist as queryable Persistent Classes, Globals, Namespaces, Stored Procedures in InterSystems IRIS 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 Persistent Classes, Globals, Namespaces, Stored Procedures in InterSystems IRIS with Approvals, Candidates, Applications, Jobs 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 Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • 02 Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting
  • 03 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.
  • 04 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.

Common sync patterns

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

Approvals, Candidates, Applications, Jobs replicate into InterSystems IRIS where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Smartrecruiters stay consistent in InterSystems IRIS, so hierarchy-driven logic and permissions don't drift.

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects Smartrecruiters objects How this pairing syncs
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. Tables is specific to InterSystems IRIS and Users to Smartrecruiters — each maps to any object or custom field on the other side.
Views SQL views expose curated slices of data for outbound replication. Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Views is specific to InterSystems IRIS and Approvals to Smartrecruiters — each maps to any object or custom field on the other side.
Schemas Schema organization scopes which tables a sync connection can see. Candidates Person records with contact details, tags, attachments, custom properties, and consent; created, updated, and searched via the Candidates API, often populated from sourcing or enrichment pipelines. Schemas is specific to InterSystems IRIS and Candidates to Smartrecruiters — each maps to any object or custom field on the other side.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. Persistent Classes is specific to InterSystems IRIS and Applications to Smartrecruiters — each maps to any object or custom field on the other side.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. 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. Globals is specific to InterSystems IRIS and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Namespaces Namespaces partition databases and determine the connection context for 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). Namespaces is specific to InterSystems IRIS and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS 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.

InterSystems IRIS Smartrecruiters Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

DeliveryEach detected change is written to Smartrecruiters through its API, with automatic retries and rate-limit backoff.

Smartrecruiters InterSystems IRIS 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 InterSystems IRIS as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • 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.
