Why teams connect Slack and Smartrecruiters

Keep the people, teams, and status that Slack and Smartrecruiters share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in Slack keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Smartrecruiters is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs Users, User groups, Files, Reactions in Slack with Offers, Users, Approvals, Candidates in Smartrecruiters bi-directionally and in real time. A person added, moved, or offboarded in Smartrecruiters creates or updates the matching user in Slack within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Slack captures details of its own, such as a corrected contact or a login identity, those can flow back to Smartrecruiters in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Archive channel messages into a warehouse or database for compliance and analytics
  • 02 Create or update records in a database when specific messages or reactions occur in a channel
  • 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

Onboarding: access ready on day one

A new hire recorded in Smartrecruiters creates the matching user in Slack with the right team and manager already set, so people can start working without waiting on a provisioning ticket.

Offboarding: no standing access after a departure

When someone is marked as leaving in Smartrecruiters, the matching account in Slack is deactivated or flagged, so departures do not leave open access behind.

One employee directory

A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.

What you can sync between Slack 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.

Slack objects Smartrecruiters objects How this pairing syncs
Users Workspace members with profile fields, synced against HR systems and identity providers. 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.
User groups Handles like @support that map to teams in external systems. 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). User groups is specific to Slack and Offers to Smartrecruiters — each maps to any object or custom field on the other side.
Files Uploads attached to messages, retrievable for archiving. Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Files is specific to Slack and Approvals to Smartrecruiters — each maps to any object or custom field on the other side.
Reactions Emoji responses that can drive workflows, such as approving a synced record. 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. Reactions is specific to Slack and Candidates to Smartrecruiters — each maps to any object or custom field on the other side.
Channels Conversations (public, private, DMs) that messages are read from and posted to. 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. Channels is specific to Slack and Applications to Smartrecruiters — each maps to any object or custom field on the other side.
Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. 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. Messages is specific to Slack and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between Slack 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.

Slack Smartrecruiters Sub-second propagation

DetectionSlack notifies Stacksync of record changes through webhook events. Events API webhooks, delivered over HTTP callbacks or Socket Mode.

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

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

Rate-limit considerations

  • Slack: Per-method rate limit tiers; message posting is additionally limited per channel.
  • 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.
