# Video call providers This page documents the server-level configuration required to support non-default [video call integration options](https://zulip.com/help/start-a-call) on a self-hosted Zulip server. ## Zoom To use the [Zoom](https://zoom.us) integration on a self-hosted installation, you'll need to register a custom Zoom app as follows: 1. Select [**Build App**](https://marketplace.zoom.us/develop/create) at the Zoom Marketplace. 1. Create an app with the **OAuth** type. - Choose an app name such as "ExampleCorp Zulip". - Select **User-managed app**. - Disable the option to publish the app on the Marketplace. - Click **Create**. 1. Inside of the Zoom app management page: - On the **App Credentials** tab, set both the **Redirect URL for OAuth** and the **Whitelist URL** to `https://zulip.example.com/calls/zoom/complete` (replacing `zulip.example.com` by your main Zulip hostname). - On the **Scopes** tab, add the `meeting:write` scope. You can then configure your Zulip server to use that Zoom app as follows: 1. In `/etc/zulip/zulip-secrets.conf`, set `video_zoom_client_secret` to be your app's "Client Secret". 1. In `/etc/zulip/settings.py`, set `VIDEO_ZOOM_CLIENT_ID` to your app's "Client ID". 1. Restart the Zulip server with `/home/zulip/deployments/current/scripts/restart-server`. This enables Zoom support in your Zulip server. Finally, [configure Zoom as the video call provider](https://zulip.com/help/start-a-call) in the Zulip organization(s) where you want to use it. ## BigBlueButton To use the [BigBlueButton](https://bigbluebutton.org/) video call integration on a self-hosted Zulip installation, you'll need to have a BigBlueButton server and configure it: 1. Get the Shared Secret using the `bbb-conf --secret` command on your BigBlueButton Server. See also [the BigBlueButton documentation](https://docs.bigbluebutton.org/admin/customize.html#extract-the-shared-secret). 2. Get the URL to your BigBlueButton API. The URL has the form of `https://bigbluebutton.example.com/bigbluebutton/` and can also be found using the `bbb-conf --secret` command. You can then configure your Zulip server to use that BigBlueButton Server as follows: 1. In `/etc/zulip/zulip-secrets.conf`, set `big_blue_button_secret` to be your BigBlueButton Server's shared secret. 2. In `/etc/zulip/settings.py`, set `BIG_BLUE_BUTTON_URL` to your to be your BigBlueButton Server's API URL. 3. Restart the Zulip server with `/home/zulip/deployments/current/scripts/restart-server`. This enables BigBlueButton support in your Zulip server. Finally, [configure BigBlueButton as the video call provider](https://zulip.com/help/start-a-call) in the Zulip organization(s) where you want to use it.
