Why teams connect Auth0 and IBM AS/400

Close the gap between your application data and your directory: IBM AS/400 and Auth0 share users, groups, and access in real time, in both directions.

Auth0 is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. IBM AS/400 holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.

Stacksync syncs Data queues, Libraries, Physical files (tables), Logical files (views) in IBM AS/400 with Users, Roles, Organizations, Organization Members in Auth0 field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.

Common use cases

  • 01 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 02 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 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

One profile, kept current

A name, department, email, or manager corrected in either system updates the other, so the profile the directory shows and the data the application reads stop drifting apart.

Provision accounts from the source of truth

When a person is added to the employee, member, or customer table in IBM AS/400, Stacksync creates the matching user in Auth0 with the right attributes, so access starts from live data instead of a manual ticket.

Deprovision the moment the record changes

When someone is marked inactive or removed in IBM AS/400, the matching account in Auth0 is disabled within seconds, closing the window between a departure and a login that still works.

What you can sync between Auth0 and IBM AS/400

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 IBM AS/400 objects How this pairing syncs
Resource Servers (APIs) API definitions and their scopes; synced so permission catalogs used for access reviews stay current. Journals and journal receivers The change log that enables log-based CDC on journaled files. Resource Servers (APIs) is specific to Auth0 and Journals and journal receivers to IBM AS/400 — 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. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Log Events is specific to Auth0 and Data queues to IBM AS/400 — 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. Libraries The schema-equivalent containers that scope which files a sync reads. Users is specific to Auth0 and Libraries to IBM AS/400 — 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. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Roles is specific to Auth0 and Physical files (tables) to IBM AS/400 — 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. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Organizations is specific to Auth0 and Logical files (views) to IBM AS/400 — 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. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Organization Members is specific to Auth0 and Members to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Auth0 and IBM AS/400

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 IBM AS/400 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 IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 Auth0 Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.

How the Auth0 and IBM AS/400 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

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

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
