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

Contact support@zulip.com to request the Bearer token that Okta will use to authenticate to your SCIM API.

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

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

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

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.

In Credentials Details, specify the following fields:

• Application username format: Email
• Update application username on: Create and update

In the Provisioning tab, click Configure API Integration, check the Enable API integration checkbox, and specify the following fields:

• Base URL for Zulip Cloud: https://example.zulipchat.com/scim/v2
• Base URL for self-hosting: https://zulip.example.com/scim/v2
• 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.

Enable the following Provisioning to App settings:

• Create Users
• Update User Attributes
• Deactivate Users

Remove all attributes in Attribute Mappings, except for the following:

• userName
• givenName
• familyName

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.

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.

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

Contact support@zulip.com to request the Secret Token that Entra will use to authenticate to your SCIM API.

Sign in to the Microsoft Entra admin center.

Go to Identity -> Applications -> Enterprise applications.

Select New application -> Create your own application.

Complete the form:

• Enter a name for your application.
• Select the option Integrate any other application you don't find in the gallery.
• Click Add to create the new app. It will be added to your Enterprise applications.

Continue to the app's management screen and click Provisioning in the left panel.

In the Provisioning Mode menu, select Automatic and specify the following fields:

• Tenant URL for Zulip Cloud: https://example.zulipchat.com/scim/v2/?aadOptscim062020.
• Tenant URL for self-hosting: https://zulip.example.com/scim/v2/?aadOptscim062020. The ?aadOptscim062020 part of it is a feature flag that needs to be added to ensure SCIM compliance by Entra ID.
• Secret Token: <token> (given to you by Zulip support)

Click Test Connection.

In the Mappings section, there are two sets of attribute mappings: one for Users and one for Groups. Make sure to set Provision Microsoft Entra ID Groups to be disabled. Provisioning of Groups is currently not supported in Zulip.

In Provision Microsoft Entra ID Users, configure the necessary mappings:

• Change userName to map to mail. Important: You need mail to be set for all your users or trying to assign them to the app will fail.
• Delete the other default entries leaving only the active and name.formatted mappings, until your list looks like the image below.

Once your configuration is complete, set the Provisioning Status to On and then click Save to start the Microsoft Entra provisioning service.

Now you can proceed to the Users and groups tab, where you can assign users to be provisioned via this integration.

Wait for the initial provisioning cycle to be started by Entra. This might take up to 40 minutes. This delay is entirely inside Entra, and not under Zulip’s control. You can also use Provision on demand in Entra to cause immediate SCIM provisioning for specific users, which is handy when testing the integration.

Follow the instructions above to configure SCIM.

Rename any Zulip groups that have the same names as groups that you want to sync. If you push a group whose name matches an existing Zulip group, the request will fail.

Open the Application you set up above for the Zulip SCIM integration, and go to the Push groups tab. This menu allows you to choose the Okta groups which should be synchronized with Zulip's user groups.
