SCIM (System for Cross-domain Identity Management) is an standard
protocol used by Single Sign-On (SSO) services and identity providers
to provision/deprovision user accounts and groups. Zulip's SCIM
integration is currently beta and has a few limitations:
- Provisioning Groups is not yet implemented.
- It has only been fully tested and documented with Okta.
The instructions below explain how to configure SCIM in Okta for Zulip
Cloud customers. Like SAML, feature is currently only available in
Zulip Cloud with the Zulip Cloud Plus plan.
These instructions can also be used by self-hosters to setup the Okta
side of SCIM for their deployment.
Configure SCIM with Okta
Before you begin, contact email support to receive
the bearer token that Okta will use to authenticate to make its SCIM requests.
In your Okta Dashboard, go to
Applications and choose
Browse App Catalog.
SCIM and select
SCIM 2.0 Test App (Header Auth).
Add and choose your
Application label. For example, you can name it
Sign-On Options. Leave the
SAML options, as this type of Okta application
doesn't actually support
SAML authentication, and you'll need to set up a separate Okta app
SAML for your Zulip organization.
Credentials Details, set
Application username format to
Update application username on to
Create and update.
The Okta app has been added. Navigate to the
Configure API Integration and check the
Enable API integration box.
Okta will ask you for the
Base URL and
API token. The
Base URL should be
yourorganization.zulipchat.com/scim/v2 and for
API token you'll set the value
given to you by 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.
To App section of the
Provisioning tab (which should be opened by default
when you continue from the previous step), edit the
Provisioning to App settings
Update User Attributes and
Attribute Mappings, remove all attributes except
Now the integration should be ready and you can
Assign users to
the app to configure their Zulip accounts to be managed by
SCIM. When you assign a user, Okta will check if the account exists
in your Zulip organization and 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
If you want to also set up SAML authentication, head to our
SAML configuration instructions. It will require
adding a separate Okta application.
