Why teams connect Auth0 and Kustomer

Keep the people Kustomer and Auth0 both track in agreement in real time: the internal users who own records in Kustomer, and the customer login accounts in Auth0.

A CRM and an identity system usually describe different populations. Kustomer tracks customers, contacts, and the deals in motion; Auth0 governs who is allowed to sign in and what they can reach. Where the two meet is people. The reps who own records in Kustomer are the same employees Auth0 provisions and disables, and when Auth0 also runs the login accounts for your product, the customers in Kustomer are the same users Auth0 authenticates. Left unconnected, a departure in Auth0 leaves stale ownership sitting in Kustomer, and a signup in Auth0 never reaches the account it belongs to.

Stacksync syncs Custom Objects (Klasses), Users, Teams, Tags in Kustomer with Clients (Applications), Resource Servers (APIs), Log Events, Users in Auth0 in real time and in both directions, matching on email or an external ID and mapping field by field. You decide which system owns which fields, and new users, role and group changes, deactivations, and account status move within seconds instead of waiting on a quarterly access review or a manual export.

Common use cases

  • 01 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • 02 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • 03 Two-way sync of Users, including user_metadata and app_metadata, with a Postgres database so internal tools read and update profiles in SQL while Auth0 stays the login source of truth.
  • 04 Provision and deprovision Users and Organization Members from an HRIS or CRM — create accounts and assign Roles on hire, delete on offboarding.

Common sync patterns

Group and entitlement membership as CRM fields

Membership of a directory group or an entitlement in Auth0 maps to fields in Kustomer, such as product tier, plan, or internal team, so segmentation reflects real access rather than a manual guess.

Where a closed deal should provision access: Kustomer drives Auth0

A won or activated customer in Kustomer can create or update the corresponding user or account in Auth0, so provisioning starts from the CRM record instead of a separate ticket.

Where Auth0 governs your workforce: CRM users kept current

New employees in Auth0 become active users in Kustomer with the right role, and group or department changes update their access and team, so the CRM's user list matches the directory without an admin re-keying it.

What you can sync between Auth0 and Kustomer

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 Kustomer objects How this pairing syncs
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. Users Agent records map conversation ownership to people in other systems. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Resource Servers (APIs) API definitions and their scopes; synced so permission catalogs used for access reviews stay current. Teams Team assignments support routing parity and reporting. Resource Servers (APIs) is specific to Auth0 and Teams to Kustomer — 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. Tags Labels on conversations and customers sync for categorization and analytics. Log Events is specific to Auth0 and Tags to Kustomer — 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. Notes Internal annotations carry context alongside synced conversations. Roles is specific to Auth0 and Notes to Kustomer — 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. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Organizations is specific to Auth0 and Customers to Kustomer — 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. Conversations Support threads across channels sync outward for analytics and CRM context. Organization Members is specific to Auth0 and Conversations to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between Auth0 and Kustomer

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

Kustomer Auth0 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 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.
  • Kustomer: Subject to the platform's API rate limits.

How the Auth0 and Kustomer 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
