# Adding The Guestbook to the Synxis Content Security Policy

## Synxis requires 3rd party scripts be given specific access in order to function properly on their booking engine. In order to get The Guestbook running on Synxis, you will need to add us as an allowed domain.

### Adding The Guestbook Domains:

1. Log-in to your Synxis BE Designer Portal and navigate to the Manage settings. If applicable, ensure you are working on the Chain level of settings management since all hotels under that chain will share the same Content Policy.
2. Select Allow Domains from the menu on the left-hand side of the screen.
3. Click on Add Domain and add " **https://\*.theguestbook.com** " (do not include quotations) to the Allowed Domains list. Then save the changes.
4. Click on Add Domain (again) and add " **https://theguestbook.com** " (do not include quotations) to the Allowed Domains list. Then save the changes.
