 ### Connections Tab
 
 Anything that connects with external service providers goes here, such as the Client ID and Secret for OAuth 2.0 applications. Please refer to respective tutorials on how to set them up and always, *always* keep those credentials confidential. If you enter a [Discord webhook](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks) here, notifications about new comments will be sent directly into a channel on your server (leave free if you do not want that). This should be a hidden moderation channel because it will receive excerpts of private comments.

 The OAuth request redirect URI should be akin to `https://your-domain.com/oauth2`, the important part being the `/oauth2` endpoint.

More customization can be achieved with the theme’s [translation filter](FILTERS.md#apply_filters-fictioneer_filter_translations-strings-). But if you want to translate the theme into a new language, you will need to include the proper [translation files](https://developer.wordpress.org/plugins/internationalization/localization/) or use a plugin.

 ### ePUBs Tab
 
 Lists all generated ePUBs with statistics, download links, and options to delete them. File names are equal to the story’s `post_name`, which is the slug inside the permalink and *not* the title. They are cleaned of any special characters and are also used to query associated stories. If you change the permalink, they will no longer match and a new ePUB will be generated, leaving the old one orphaned. This is not terrible but takes up space.
