Why teams connect Onelogin and Slack
Keep the users, groups, and profile details that Slack and Onelogin share consistent in real time, so who can work in Slack always matches who your directory in Onelogin says belongs there.
Onelogin is where a company records who its people are: their accounts, the groups and roles they hold, and the attributes attached to each one. Slack is where a slice of those same people do their work, as agents, members, or seats, and every one of them needs a matching account with the right access. When a directory and a productivity tool are maintained by hand, someone added, moved, or offboarded in one becomes a stale entry in the other within the hour.
Stacksync syncs Reactions, Channels, Messages, Threads in Slack with Groups, Mappings (mapping rules), Events, Authentication factors (MFA) in Onelogin bi-directionally and in real time. A user created, renamed, moved between groups, or deactivated in either system updates the matching record in the other within seconds, with field-level mapping and conflict resolution in place of CSV uploads and nightly IT batch jobs.
That matters most at the edges of employment. When both systems agree on who has an account, which groups they belong to, and whether they are still active, granting access on day one and revoking it on the last day stops being a manual checklist that trails the directory.
Common use cases
- 01 Create or update records in a database when specific messages or reactions occur in a channel
- 02 Alert an operations channel when a data sync detects conflicts or validation failures
- 03 Keep Role membership aligned with application or database entitlement tables so each role's assigned users match who should hold that access.
- 04 Read Users, Apps, and Groups into a database for identity, license, and app-assignment inventory across the OneLogin account.
Common sync patterns
Close access when someone leaves
When a user is disabled or removed in Onelogin, their account in Slack is deactivated in step, so offboarding shuts down access everywhere instead of leaving a live login behind.
Keep profile attributes current
A person's name, email, department, manager, or phone number corrected in either system updates the other, so the productivity tool shows the same details the directory holds of record.
Mirror group and role membership
Moving a user between groups or roles in Onelogin updates their team, permission set, or seat in Slack, so what someone can do reflects where they sit in the directory.
What you can sync between Onelogin and Slack
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.
| Onelogin objects | Slack objects | How this pairing syncs | |
|---|---|---|---|
| Users User accounts (email, username, custom attributes, status, roles); full CRUD via the v2 Users API - create, update, delete, set password, lock/unlock, and add or remove role assignments. | Users Workspace members with profile fields, synced against HR systems and identity providers. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Roles Roles that bundle app access; created, updated, and deleted via the Roles API, with users, admins, and apps assigned to each role. | User groups Handles like @support that map to teams in external systems. | Roles is specific to Onelogin and User groups to Slack — each maps to any object or custom field on the other side. | |
| Apps (app instances) Connected SAML/OIDC application configs on the account; create, update, delete, and assign to users and roles - the writable app catalog. | Files Uploads attached to messages, retrievable for archiving. | Apps (app instances) is specific to Onelogin and Files to Slack — each maps to any object or custom field on the other side. | |
| Groups Account groups used for mapping and reporting; listed and read through the API, which has no create or update endpoint, so groups are read-only. | Reactions Emoji responses that can drive workflows, such as approving a synced record. | Groups is specific to Onelogin and Reactions to Slack — each maps to any object or custom field on the other side. | |
| Mappings (mapping rules) Attribute-driven rules that assign roles and app access; full CRUD via the Mappings API, then reapplied across matching users. | Channels Conversations (public, private, DMs) that messages are read from and posted to. | Mappings (mapping rules) is specific to Onelogin and Channels to Slack — each maps to any object or custom field on the other side. | |
| Events Audit log of every authentication and admin action; read-only, filtered by since/until, and pushed live through the Event Webhook. | Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. | Events is specific to Onelogin and Messages to Slack — each maps to any object or custom field on the other side. |
How changes propagate between Onelogin and Slack
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.
Onelogin Slack Sub-second propagation
DetectionOnelogin notifies Stacksync of record changes through webhook events. Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time.
DeliveryEach detected change is written to Slack through its API, with automatic retries and rate-limit backoff.
Slack Onelogin 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 Onelogin through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Onelogin: Account-level limit of 5,000 API calls per hour shared across all access tokens; responses carry X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset, over-limit calls return HTTP 429, and the count resets each hour. Paid plans can request an increase.
- Slack: Per-method rate limit tiers; message posting is additionally limited per channel.

How the Onelogin and Slack connectors work
Onelogin
- Integration surface
- OneLogin API (REST, v1 and v2 resource endpoints on <subdomain>.onelogin.com) plus the Event Webhook (Event Broadcaster) for event delivery
- Authentication
- OAuth 2.0 client credentials - an admin generates an API credential pair (client_id + client_secret) in the OneLogin portal and exchanges it at POST /auth/oauth2/v2/token for a bearer access token sent on every call; each credential carries a scope (Manage all, Manage users, Read users, etc.) that governs read vs write.
- Change detection
- Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time; the Events API also supports polling with since/until time filters and pagination for historical backfill.

FAQ
Onelogin and Slack integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Onelogin and Slack: authenticate both systems, choose the objects to sync (such as Onelogin's Users and Roles), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Slack: Message content beyond plain text is structured with Block Kit, which a sync layer must compose when writing. Onelogin: Some write calls are queued to OneLogin's job system and can take up to about five minutes to finish processing rather than completing synchronously. Stacksync's field mapping accounts for these differences between Onelogin and Slack without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Onelogin and Slack records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Onelogin and Slack connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Onelogin–Slack integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Onelogin and Slack. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Onelogin: Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time; the Events API also supports polling with since/until time filters and pagination for historical backfill. On Slack: Events API webhooks, delivered over HTTP callbacks or Socket Mode. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
