Why teams connect Auth0 and ClickHouse

Land the users, groups, and access events from Auth0 in ClickHouse continuously for security analytics, and write computed results back — without building or maintaining a pipeline.

Auth0 is the record of who exists and what they can reach; ClickHouse is where the business measures everything else. The two overlap on people and their access — the same users, groups, roles, and events that Auth0 governs are what security, compliance, and analytics teams want to query in ClickHouse. Getting them there usually means a brittle export that runs overnight and hands auditors a snapshot that is already out of date.

Stacksync syncs Log Events, Users, Roles, Organizations from Auth0 into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse, such as risk scores or access-review decisions, can be written back to attributes in Auth0 where the identity team acts on them. Schema changes are handled, API limits are managed, and the sync is something you configure rather than a pipeline you keep alive.

Common use cases

  • 01 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 02 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 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

Access governance on joined data

Join Auth0's users and group memberships with HR, product, and usage data already in ClickHouse to surface who holds access they no longer need.

Queryable history for audit and compliance

A continuously synced copy in ClickHouse gives you a durable, queryable record of identity and access state for access reviews, SOC 2, and audit questions.

Risk and review results back on the account

Risk scores, anomaly flags, or access-review outcomes computed in ClickHouse write back to attributes on the matching user in Auth0, where the identity team can act on them.

What you can sync between Auth0 and ClickHouse

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 ClickHouse objects How this pairing syncs
Log Events Tenant events (logins, signups, failed logins, admin changes) from /api/v2/logs; read-only, streamed into a warehouse for security analytics. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Log Events is specific to Auth0 and Dictionaries to ClickHouse — 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. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Users is specific to Auth0 and Tables (MergeTree family) to ClickHouse — each maps to any object or custom field on the other side.
Roles RBAC role definitions and their permissions; synced with a database to audit which users hold which access, and assigned to Users from either side. Databases Namespaces that group tables and scope permissions for sync users. Roles is specific to Auth0 and Databases to ClickHouse — each maps to any object or custom field on the other side.
Organizations B2B customer tenants under /api/v2/organizations; synced two-way with a CRM or customer database to keep account records aligned with Auth0 orgs. Views Saved queries used as curated, read-only sync sources. Organizations is specific to Auth0 and Views to ClickHouse — each maps to any object or custom field on the other side.
Organization Members Membership records linking Users to Organizations with roles; written to provision and deprovision access as accounts change. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Organization Members is specific to Auth0 and Materialized views to ClickHouse — 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. Distributed tables Query-routing tables over cluster shards in self-managed deployments. Connections is specific to Auth0 and Distributed tables to ClickHouse — each maps to any object or custom field on the other side.

How changes propagate between Auth0 and ClickHouse

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 ClickHouse 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 applied to ClickHouse as a row-level write, with types converted between the two schemas.

ClickHouse Auth0 Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

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.

How the Auth0 and ClickHouse 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
Capabilities
read · write · webhooks
Rate limits
Per-tenant limit of about 15 Management API requests/second (bursts to 50) on paid tenants; X-RateLimit-* headers and HTTP 429 signal throttling

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
