Configure the connection to your Jellyfin server under System Settings → Servers → Add New Server.

Field
Value

Name
A label for the server.

Hostname / IP Address
The Jellyfin server hostname or IP.

Module
PUQ Jellyfin Family.

Username
A Jellyfin administrator username.

Password
That administrator's password.

Access Hash
A Jellyfin API key (Jellyfin Dashboard → API Keys).

Secure (SSL)
Enable if Jellyfin is served over HTTPS.

Port
Jellyfin port (default 8096, or 443 when SSL is enabled).

In the Server Details section select Module → PUQ Jellyfin Family, fill in the Username, Password and Access Hash (API key), tick Secure for SSL and set the Port.

Use Test Connection to confirm WHMCS can reach Jellyfin and authenticate. The module authenticates with the username / password + API key to obtain an access token, then calls System/Info to verify connectivity. On success some fields are auto-filled and the status shows Connection successful.
Finally, assign the server (or a server group that contains it) to your Jellyfin Family product under the product's Module Settings.
