Why teams connect Kustomer and Smartrecruiters

Keep the people who own accounts in Kustomer in step with the workforce records in Smartrecruiters, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.

Kustomer runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Smartrecruiters. Smartrecruiters is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.

Stacksync syncs Companies, Custom Objects (Klasses), Users, Teams in Kustomer with Job Postings, Interviews, Offers, Users in Smartrecruiters field by field, in real time, and in both directions. You decide which system owns which fields, so Smartrecruiters stays authoritative on roles and org structure while Kustomer keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • 02 Escalate conversation-derived signals into the CRM as tasks or opportunities
  • 03 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.
  • 04 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.

Common sync patterns

Where Smartrecruiters tracks people the business also engages: contacts stay in sync

A person recorded in Smartrecruiters, such as a candidate or applicant, can create or update the matching contact in Kustomer, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

New team members provisioned when they are hired

When Smartrecruiters records a new hire, a matching user or owner is created in Kustomer, so a new rep can start working accounts without waiting on a manual setup ticket.

Ownership and territory follow the org chart

When a person changes team, manager, or region in Smartrecruiters, their accounts and territory assignments in Kustomer update to match, so pipeline stays with the right owner.

What you can sync between Kustomer 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.

Kustomer objects Smartrecruiters objects How this pairing syncs
Users Agent records map conversation ownership to people in other systems. Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. 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. Custom Objects (Klasses) is specific to Kustomer and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Teams Team assignments support routing parity and reporting. 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). Teams is specific to Kustomer and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Tags Labels on conversations and customers sync for categorization and analytics. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Tags is specific to Kustomer and Interviews to Smartrecruiters — each maps to any object or custom field on the other side.
Notes Internal annotations carry context alongside synced conversations. 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). Notes is specific to Kustomer and Offers to Smartrecruiters — each maps to any object or custom field on the other side.
Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Customers is specific to Kustomer and Approvals to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between Kustomer 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.

Kustomer Smartrecruiters Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

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

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

Rate-limit considerations

  • Kustomer: Subject to the platform's 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.
