SCIM Provisioning

Gatewyse implements the SCIM 2.0 protocol so your identity provider (IdP) can automatically create, update, deactivate, and role-map users without any manual admin work. SCIM complements SSO: SSO authenticates users at login, while SCIM provisions and lifecycle-manages their accounts and roles out-of-band — an IdP administrator can add a user to a group and have them provisioned into the gateway before they ever sign in.

The SCIM API is mounted at /scim/v2 and every operation is scoped to a single tenant by the bearer token presented on the request.

What SCIM Is For

Automated onboarding — new users in your IdP are pushed to the gateway on a schedule or in real time, no per-user setup in the admin dashboard.
Automated offboarding — when a user is removed from the IdP, they are deprovisioned (soft-disabled) in the gateway.
Role synchronization — IdP group membership maps to gateway roles (see Groups → Roles).

Enabling SCIM

SCIM is authenticated with a per-tenant bearer token. The token is SHA-256 hashed with the same scheme as API keys and only the hash is stored (tenant.scim.tokenHash); the plaintext is shown once at issuance and never persisted. Enabling SCIM (tenant.scim.enabled) and issuing the token are tenant-level operations performed by an administrator.

Configure your IdP’s SCIM integration with:

Base URL — https://gateway.example.com/scim/v2
Authentication — OAuth Bearer Token
Token — the per-tenant SCIM token issued for the tenant

Every request must carry the token:

curl https://gateway.example.com/scim/v2/Users \
  -H "Authorization: Bearer <scim-token>"

A request with a missing, malformed, or unrecognized token is rejected with a SCIM 401 error body. Because the token resolves to exactly one tenant, no SCIM operation can ever reach another tenant’s users.

Endpoints

Responses use the application/scim+json media type. The ServiceProviderConfig advertises support for PATCH and filtering, and no support for bulk operations, sort, etag, or changePassword.

Method	Path	Purpose
`GET`	`/ServiceProviderConfig`	Advertised capabilities and auth scheme
`GET`	`/ResourceTypes`	The `User` and `Group` resource types
`GET`	`/Schemas`	Supported attribute schemas
`GET`	`/Users`	List users (supports `filter`, `startIndex`, `count`)
`POST`	`/Users`	Provision a new user
`GET`	`/Users/:id`	Fetch a single user
`PUT`	`/Users/:id`	Full replace of the user’s mutable attributes
`PATCH`	`/Users/:id`	Partial update (most commonly toggling `active`)
`DELETE`	`/Users/:id`	Deprovision (soft-disable) the user
`GET`	`/Groups`	List groups (roles)
`GET`	`/Groups/:id`	Fetch a single group and its members
`PATCH`	`/Groups/:id`	Add or remove group members (assign/unassign a role)

User Lifecycle

Provisioning

POST /Users creates a user in the calling tenant. The email is taken from userName (or the primary emails entry), name.givenName/name.familyName populate the user’s name, and externalId is stored for future matching. Newly provisioned users receive the tenant’s base user role — role elevation is never driven from the User resource, only through Group membership.

Provisioning is idempotent-safe: if a user with the same email or externalId already exists, the request returns SCIM 409 uniqueness rather than creating a duplicate.

curl -X POST https://gateway.example.com/scim/v2/Users \
  -H "Authorization: Bearer <scim-token>" \
  -H "Content-Type: application/scim+json" \
  -d '{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
    "userName": "jane@example.com",
    "externalId": "idp-user-123",
    "name": { "givenName": "Jane", "familyName": "Doe" },
    "active": true
  }'

Updates

PUT /Users/:id replaces the mutable attributes (userName, externalId, name, active) in full.
PATCH /Users/:id applies partial changes. It accepts both the { "path": "active", "value": false } and the { "value": { "active": false } } operation shapes, for replace and add operations. Recognized attributes are active, userName, name.givenName, name.familyName, and externalId; unknown attributes are ignored rather than failing the whole request.

Deprovisioning

Deprovisioning is a soft disable, never a hard delete. Setting active: false (via PATCH or PUT) or calling DELETE /Users/:id moves the user to the DEACTIVATED status. The user record — and with it all audit history and request-log attribution — is preserved. Re-activating the user (active: true) restores access.

# Deprovision via PATCH
curl -X PATCH https://gateway.example.com/scim/v2/Users/<id> \
  -H "Authorization: Bearer <scim-token>" \
  -H "Content-Type: application/scim+json" \
  -d '{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:PatchOp"],
    "Operations": [{ "op": "replace", "path": "active", "value": false }]
  }'

Groups → Roles

A SCIM Group maps one-to-one to a gateway role; the group’s members are the users holding that role. Listing groups (GET /Groups) returns the tenant’s roles — the seeded system roles plus the tenant’s own custom roles — with displayName set to the role name.

Membership is synchronized with PATCH /Groups/:id:

An add operation with member values assigns the role to those users.
A remove operation unassigns it.

curl -X PATCH https://gateway.example.com/scim/v2/Groups/<roleId> \
  -H "Authorization: Bearer <scim-token>" \
  -H "Content-Type: application/scim+json" \
  -d '{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:PatchOp"],
    "Operations": [
      { "op": "add", "value": [{ "value": "<userId>" }] }
    ]
  }'

Escalation Guard

The super-admin role is never exposed or assignable through SCIM. It is excluded from the GET /Groups listing, and any attempt to PATCH a group that resolves to super-admin is rejected with SCIM 403 mutability. This means a tenant’s IdP — whether misconfigured or compromised — can grant tenant-scoped roles (tenant-admin, org-admin, and so on) through group membership, but can never escalate a user to platform super-admin.

Relationship to SSO

SCIM and SSO are independent and complementary:

SSO handles authentication — verifying a user’s identity at login and (optionally) re-syncing their roles from IdP group claims on each sign-in.
SCIM handles provisioning — creating, updating, deprovisioning, and role-mapping accounts out-of-band, independent of whether the user has ever logged in.

Both enforce the same escalation guard: neither path can assign super-admin. Most enterprise deployments run both — SSO for login, SCIM for lifecycle management.
