Hello @parassachan , the entire Support Portal is customizable. Here is a guide that talks about this. It references freshdesk but the process is the same in freshservice

Hi @parassachan , As @zachary.king has mentioned our end user portal can be customized and we also have few integration partners who can help you with extensive customization like applying themes etc. Please do reach out to our support team if you have any specific changes and our team can check the feasibility for the same.

Hi @rajagopal.baladhandayutham

Please send me a few integration partners that assist with Freshservice UI themes.

Thanks
