The parser does not query other accounts or evaluate arbitrary expressions. ## Resolution and errors Names are case-insensitive. This guide lists the 127 current public Headless variables. A listed variable without data for the event renders as `N/A`; an unknown name or invalid syntax is rejected. The parser may retain internal legacy identifiers that are not part of this public catalog. ## Formatting functions `{lower(variable)}` lowercases text and `{proper(variable)}` applies title case; numeric values passed to `proper` receive thousands separators. Each function accepts exactly one known variable, not an expression. ### Profile and formatting ```headless-script Syntax theme={null} {user.display_name} ``` ```headless-script Example theme={null} {user.display_name} in {guild.name} ``` ```headless-script Syntax theme={null} {lower(user.name)} ``` ```headless-script Example theme={null} {lower(user.name)} · {proper(guild.count)} ``` ```headless-script Syntax theme={null} {user.mention} ``` ```headless-script Example theme={null} {user.mention} · {channel.mention} ``` ## Event scope The catalog covers values from current Headless events, including server, user, channel, Roblox, YouTube, leveling, boosts, and moderation. A recognized key may still resolve to `N/A` when an event does not provide it. Reserved fields for unavailable providers are omitted from this public guide. ## Headless-specific variables Level-up notices add `{level}`, `{xp}`, `{total_xp}`, and `{gained}` alongside `{level.new_rank}` and `{level.user_xp}`. Booster Roles announcements add `{boost_count}` (the server total), `{boost_tier}`, and `{boost_since}` (the boost date or `N/A`). In that event `{boost.count}` is `1` for a member currently boosting and `N/A` when there is no boost date. The `{user}`, `{mention}`, `{username}`, and `{server}` aliases can be adapted to each event. ### Levels and boosts ```headless-script Syntax theme={null} {level} ``` ```headless-script Example theme={null} {user} reached level {level}; +{gained} XP; {total_xp} total ``` ```headless-script Syntax theme={null} {boost_count} ``` ```headless-script Example theme={null} {mention} boosted {server}: tier {boost_tier}, {boost_count} server boosts ``` > [!NOTE] > > The catalog comes from Headless's original renderer and is checked against `build_template_context`. Some keys exist only during specific events; a recognized key can resolve to `N/A` when the event does not provide that value. ## Current runtime variables This public catalog documents 127 variables used by current Headless events. Some internal legacy variables are not included; use this list when configuring compatible messages and previews. > **Server** > > ```text theme={null} > {guild.name} > {guild.id} > {guild.count} > {guild.region} > {guild.shard} > {guild.owner_id} > {guild.created_at} > {guild.created_at_timestamp} > {guild.emoji_count} > {guild.role_count} > {guild.boost_count} > {guild.boost_tier} > {guild.preferred_locale} > {guild.key_features} > {guild.icon} > {guild.banner} > {guild.splash} > {guild.discovery} > {guild.max_presences} > {guild.max_members} > {guild.max_video_channel_users} > {guild.afk_timeout} > {guild.afk_channel} > {guild.channels} > {guild.channels_count} > {guild.text_channels} > {guild.text_channels_count} > {guild.voice_channels} > {guild.voice_channels_count} > {guild.category_channels} > {guild.category_channels_count} > {guild.vanity} > ``` > **User** > > ```text theme={null} > {user} > {user.id} > {user.mention} > {user.name} > {user.tag} > {user.avatar} > {user.guild_avatar} > {user.display_avatar} > {user.joined_at} > {user.joined_at_timestamp} > {user.created_at} > {user.created_at_timestamp} > {user.display_name} > {user.boost} > {user.boost_since} > {user.boost_since_timestamp} > {user.color} > {user.top_role} > {user.role_list} > {user.role_text_list} > {user.bot} > {user.badges_icons} > {user.badges} > {user.join_position} > {user.join_position_suffix} > {author} > {author.name} > {author.nickname} > {author.discriminator} > ``` > **Channel, date, and time** > > ```text theme={null} > {channel.name} > {channel.id} > {channel.mention} > {channel.topic} > {channel.type} > {channel.category_id} > {channel.category_name} > {channel.position} > {channel.slowmode_delay} > {date.now} > {date.utc_timestamp} > {date.now_proper} > {date.now_short} > {date.now_shorter} > {date.utc_now} > {date.utc_now_proper} > {date.utc_now_short} > {date.utc_now_shorter} > {time.now} > {time.now_military} > {time.utc_now} > {time.utc_now_military} > ``` > **Roblox** > > ```text theme={null} > {roblox.name} > {roblox.id} > {roblox.followers} > {roblox.following} > {roblox.display_name} > {roblox.description} > {roblox.verified} > {roblox.premium} > {roblox.rap} > {roblox.created} > {roblox.created.raw} > {roblox.created.short} > {roblox.age} > {roblox.banned} > {roblox.last_online} > {roblox.last_online.raw} > {roblox.last_online.short} > {roblox.avatar} > {roblox.badges} > {roblox.previous_names} > {roblox.url} > ``` > **YouTube** > > ```text theme={null} > {youtube.channel.name} > {youtube.channel.url} > {youtube.channel.id} > {youtube.video.url} > {youtube.video.title} > {youtube.video.thumbnail_url} > ``` > **Levels, boosts, and moderation** > > ```text theme={null} > {level.new_rank} > {level.user_xp} > {boost.count} > {bumpreminder.last_user_bump} > {bumpreminder.next_bump} > {moderator} > {moderator.name} > {moderator.tag} > {moderator.avatar} > {moderator.bot} > {moderator.color} > {moderator.mention} > {moderator.created_at} > {moderator.id} > {reason} > {duration} > {invite_url} > ``` ## Steps **1. Choose the module route** Confirm where the message will be used before choosing a variable. **2. Insert the token** Wrap the key in braces and preserve dots in nested names. **3. Preview a real event** Check replacements and `N/A` values with the module's preview command when available. ## Related pages * [Ticket variables](/docs/en/server/tickets/variables.md) * [Welcome](/docs/en/server/welcome.md) * [Sticky Messages](/docs/en/server/sticky-messages.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
