Requirements

OBS Studio with obs-websocket support enabled.
A reachable WebSocket address, port and password when authentication is enabled.

Connect

In OBS, open Tools → WebSocket Server Settings.
Enable Enable WebSocket server. Keep authentication enabled unless you have a specific local setup that does not need it, then select Apply.
Select Show Connect Info and keep the displayed server IP, port and password available.

In Streaming Hub, open Services → OBS, or double-click OBS in the status bar.
Enter the OBS server IP or host, port and password in the matching fields.
Select Apply or Save, then confirm that Diagnostics reports Connected: True.

Streaming Hub OBS project settings with host, port, hidden password and connected diagnostics — Use the values from Show Connect Info. The documentation image hides the password deliberately.

Verify the connection

The OBS service indicator shows a connected state and Diagnostics reports Connected: True. Open the OBS workspace and select Refresh to confirm that current OBS resources can be read.

OBS entities and bindings

After connecting, open the OBS workspace to create reusable Slots and Assets. Bind each portable Slot to the matching scene, text source, media source, filter or other item in the connected OBS instance.

OBS workspace Slots view with a media slot, capabilities and a binding to an OBS input — Slots are reusable references. The selected media slot shows its accepted asset types and its binding in the active profile.

Use Assets for reusable images, media, playlists and other content that a Slot can reference. The image path in this example has been hidden for privacy.

OBS workspace Assets view with a selected image asset and preview; local file paths hidden — Assets keep reusable content separate from the OBS resource or Slot that displays it. Local file paths are redacted.

See OBS workspace for the annotated interface and the difference between Slots and Assets.

Limitations

Actions depend on the names and identifiers available in the connected OBS instance. Renaming or removing OBS resources can invalidate saved references.

Troubleshooting

Check the service status and filter the Log panel by the integration source. Reopen the integration settings to check connection details, enabled options and required external-service permissions.
