Trigger reference

Every event that can start a flow, what it fires on, and the extra variables it puts into the run. Entries written as {var:name} are read with that exact syntax in step fields; the rest are bare variables like {user}.

Commands and input

The ways a member deliberately runs a flow.

Trigger	Fires when	Extra variables
Command `command`	A slash command plus prefix alias - the flow name becomes the command. Supports parent + group for subcommands.	{args}, {arg:N}, {option:name}, {optionId:name}
User context menu `userContext`	Right-click a member, then Apps. The flow name is the menu label.	{targetUser}, {targetUserId}, {targetUsername}
Message context menu `messageContext`	Right-click a message, then Apps.	{targetUser} / {targetUserId} / {targetUsername} = the author, {var:targetMessageId}, {var:targetContent}
Button click `button`	A button with the matching custom ID (created by a Buttons node) is clicked.	{selected} = the button custom ID
Select menu `selectMenu`	A dropdown with the matching custom ID (created by a Select Menu node) is used.	{selected}, {var:selectedIds}, {var:selectedData} (resolved JSON)

Messages

React to chat traffic. A keyword flow with a blank keyword fires on every message in its channel.

Trigger	Fires when	Extra variables
Keyword `keyword`	A message contains the phrase. Blank keyword = every message, but a channel scope is required.	{content}, {messageId}, {args}

Message reply `messageReply`	Someone replies to one of the bot's messages.	{content}, {var:replyToId}, {var:replyToContent}
Message deleted `messageDelete`	A message is deleted. {content} may be empty for old uncached messages.	{content}, {messageId}
Message edited `messageUpdate`	A message is edited.	{oldContent}, {content}, {messageId}
Attachment posted `attachmentPost`	A message with attachments lands. Optional file-type filter.	{var:attachmentCount}, {var:attachmentNames}, {var:attachmentUrl}
Link posted `linkPost`	A message containing a URL lands. Optional domain filter (wildcards allowed).	{var:linkUrl}, {var:linkDomain}
First message `firstMessage`	A member's first-ever message in the server - survives restarts. Premium.	{user}, {content}
Poll ended `pollEnd`	A native Discord poll closes. Premium.	{var:pollQuestion}, {var:pollResults}, {var:pollMessageId}

Members

Joins, leaves, and member lifecycle events.

Server changes

Admin and audit events. "Server changed" is one trigger with a watch-for dropdown; channel and role deletion also have dedicated triggers that identify who did it.

Trigger	Fires when	Extra variables

Things every trigger shares

The base variables are always there: {user}, {userId}, {username}, {server}, {memberCount}, {channel} are filled on every run, so a member-join flow can greet the member without extra steps. On triggers with no human actor (schedules, guild events) the author fields resolve to the bot itself.
Output channel: event triggers take a channel ID in their config - that is where message steps post. Blank falls back to the channel the event happened in, then the system channel.
Gates still apply: allowed roles, allowed channels, cooldown, and daily limit work on event triggers too - a keyword flow can still be staff-only.
Premium triggers: minecraftEvent, webhookEvent, httpWatch, streamAlert, cronSchedule, firstMessage, presenceUpdate, and pollEnd require a paid plan - enforced when the flow is saved.
Intents: the bot requests Discord privileged intents on demand - presenceUpdate flows request Guild Presences, pollEnd flows request Polls - so adding one of these triggers may take a restart to activate.
