Why teams connect Auth0 and Lemlist
Keep the users, groups, and profile details that Lemlist and Auth0 share consistent in real time, so who can work in Lemlist always matches who your directory in Auth0 says belongs there.
Auth0 is where a company records who its people are: their accounts, the groups and roles they hold, and the attributes attached to each one. Lemlist 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 Activities, Unsubscribes, Webhooks, Team Members in Lemlist with Clients (Applications), Resource Servers (APIs), Log Events, Users in Auth0 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 Stop or pause sequences automatically when a reply converts to a deal in the CRM
- 02 Mirror campaign performance data into BI tools for outbound reporting across senders
- 03 Provision and deprovision Users and Organization Members from an HRIS or CRM — create accounts and assign Roles on hire, delete on offboarding.
- 04 Replicate Roles and Resource Server scopes into a database to audit which Users hold which permissions across every Application.
Common sync patterns
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 Auth0 updates their team, permission set, or seat in Lemlist, so what someone can do reflects where they sit in the directory.
One record per person
People matched across both systems on email or an external ID stay linked, so every account and action in Lemlist ties back to the right identity in Auth0.
What you can sync between Auth0 and Lemlist
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.
| Auth0 objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| Organization Members Membership records linking Users to Organizations with roles; written to provision and deprovision access as accounts change. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Organization Members is specific to Auth0 and Leads to Lemlist — each maps to any object or custom field on the other side. | |
| Connections Identity-provider configs (database, social, enterprise SAML/OIDC); typically read out to inventory how each tenant authenticates. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Connections is specific to Auth0 and Activities to Lemlist — each maps to any object or custom field on the other side. | |
| Clients (Applications) Registered applications and their metadata under /api/v2/clients; mirrored to a database for app and credential inventories. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Clients (Applications) is specific to Auth0 and Unsubscribes to Lemlist — each maps to any object or custom field on the other side. | |
| Resource Servers (APIs) API definitions and their scopes; synced so permission catalogs used for access reviews stay current. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Resource Servers (APIs) is specific to Auth0 and Webhooks to Lemlist — each maps to any object or custom field on the other side. | |
| Log Events Tenant events (logins, signups, failed logins, admin changes) from /api/v2/logs; read-only, streamed into a warehouse for security analytics. | Team Members Sender and seat records map outreach activity to reps in other systems. | Log Events is specific to Auth0 and Team Members to Lemlist — each maps to any object or custom field on the other side. | |
| Users Core identity records with profile fields plus user_metadata and app_metadata; synced two-way (create, update, delete) via /api/v2/users. Credentials are never returned. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Users is specific to Auth0 and Campaigns to Lemlist — each maps to any object or custom field on the other side. |
How changes propagate between Auth0 and Lemlist
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.
Auth0 Lemlist Sub-second propagation
DetectionAuth0 notifies Stacksync of record changes through webhook events. Event Streams and Log Streams deliver near-real-time user.created/updated/deleted and tenant events to a custom webhook or Amazon EventBridge.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Lemlist Auth0 Sub-second propagation
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.
DeliveryEach detected change is written to Auth0 through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Auth0: Per-tenant limit of about 15 Management API requests/second (bursts to 50) on paid tenants; X-RateLimit-* headers and HTTP 429 signal throttling.
- Lemlist: Subject to the platform's API rate limits.

How the Auth0 and Lemlist connectors work
Auth0
- Integration surface
- Management API v2 (REST); Authentication API issues the access token
- Authentication
- OAuth 2.0 client credentials from a machine-to-machine application; scoped Bearer JWT where each operation needs its own scope (e.g. read:users, create:users, update:users) or returns 403
- Change detection
- Event Streams and Log Streams deliver near-real-time user.created/updated/deleted and tenant events to a custom webhook or Amazon EventBridge; polling falls back to the Get Users search filtered on updated_at

FAQ
Auth0 and Lemlist integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Auth0 and Lemlist: authenticate both systems, choose the objects to sync (such as Auth0's Organization Members and Connections), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Auth0 and Lemlist: Keep profile attributes current; Mirror group and role membership; One record per person. 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.
-
Auth0: Management API v2 (REST); Authentication API issues the access token. Authentication: OAuth 2.0 client credentials from a machine-to-machine application; scoped Bearer JWT where each operation needs its own scope (e.g. read:users, create:users, update:users) or returns 403. Lemlist: REST API. Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.
-
Lemlist: Lemlist's data model attaches leads to campaigns, so cross-campaign views of a prospect are assembled by the consuming system rather than provided natively, which makes CRM sync the practical system of record. Auth0: Paid tenants are limited to roughly 15 Management API requests per second with bursts to 50, applied per tenant across all integrations; responses expose X-RateLimit-* headers and return 429 when exceeded. Stacksync's field mapping accounts for these differences between Auth0 and Lemlist 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 Auth0 and Lemlist records are not retained after a sync operation.
