SCIM provisioning

This feature is only available to organization owners and administrators.

SCIM (System for Cross-domain Identity Management) is a standard protocol used by Single Sign-On (SSO) services and identity providers to provision/deprovision user accounts and groups. Zulip supports SCIM integration, both in Zulip Cloud and for self-hosted Zulip servers. This page describes how to configure SCIM provisioning for Zulip.

Zulip's SCIM integration has the following limitations:

  • Provisioning Groups is not yet implemented.
  • While Zulip's SCIM integration is generic, it has only been fully tested and documented with Okta's SCIM provider, and it is possible minor adjustments may be required. Zulip support is happy to help customers configure this integration with SCIM providers that do not yet have detailed self-service documentation on this page.

Zulip Cloud customers who wish to use this feature must upgrade to the Zulip Cloud Plus plan.

Configure SCIM

  1. Make sure your Zulip Cloud organization is on the Zulip Cloud Plus plan.

  2. Contact to request the Bearer token that Okta will use to authenticate to your SCIM API.

  3. In your Okta Dashboard, go to Applications, and select Browse App Catalog.

  4. Search for SCIM and select SCIM 2.0 Test App (Header Auth).

  5. Click Add and choose your Application label. For example, you can name it "Zulip SCIM".

  6. Continue to Sign-On Options. Leave the SAML options as they are. This type of Okta application doesn't actually support SAML authentication, and you'll need to set up a separate Okta app to activate SAML for your Zulip organization.

  7. In Credentials Details, specify the following fields:

    • Application username format: Email
    • Update application username on: Create and update
  8. In the Provisioning tab, click Configure API Integration, check the Enable API integration checkbox, and specify the following fields:

    • Base URL:
    • API token: Bearer token (given to you by Zulip support)

    When you proceed to the next step, Okta will verify that these details are correct by making a SCIM request to the Zulip server.

  9. Enable the following Provisioning to App settings:

    • Create Users
    • Update User Attributes
    • Deactivate Users
  10. Remove all attributes in Attribute Mappings, except for the following:

    • userName
    • givenName
    • familyName
  11. Optional: If you'd like to also sync user role, you can do it by adding a custom attribute in Okta. Go to the Profile Editor, click into the entry of the SCIM app you've just set up and Add Attribute. Configure the following:

    • Data type: string
    • Variable name: role
    • External name: role
    • External namespace: urn:ietf:params:scim:schemas:core:2.0:User

    With the attribute added, you will now be able to set it for your users directly or configure an appropriate Attribute mapping in the app's Provisioning section. The valid values are: owner, administrator, moderator, member, guest.

  12. Now that the integration is ready to manage Zulip user accounts, assign users to the SCIM app.

    • When you assign a user, Okta will check if the account exists in your Zulip organization. If it doesn't, the account will be created.
    • Changes to the user's email or name in Okta will automatically cause the Zulip account to be updated accordingly.
    • Unassigning a user from the app will deactivate their Zulip account.

Once SCIM has been configured, consider also configuring SAML.
