Node reference

Every node a graph can use, one page each: what it takes, what it returns, when to reach for it, and a graph that uses it. The field tables come from the registry the canvas inspector reads, so they list the fields the node takes. The groups match the canvas palette, and the ? beside a step’s kind in the inspector opens its page here.

Sources

Node	Kind	What it does
Trigger	trigger	Start this graph from an event: a bus subscription or a webhook the graph owns.

Activities

Node	Kind	What it does
HTTP request	http	Make an HTTP request to an external service.
Shell command	shell	Run a shell command on an agent; its spool output set values become the node’s output.
Polyglot script	code	Run a script in your language of choice on an agent.
Sub-workflow	workflow	Run another workflow and wait for it.
Transform	transform	Reshape a value with JavaScript: build the output field by field, or write the expression yourself.

Flow

Node	Kind	What it does
Switch	switch	Route to one branch by evaluating conditions in order.
Fan out	fan_out	Run a body once per item, in parallel.
Wait	wait	Pause the run for a fixed duration, or until a signal arrives.
Approval	approval	Pause for a human to approve or reject before continuing.
Wait for event	event	Wait until a matching event arrives on the project bus.
Emit event	emit	Publish an event onto the project bus.
State cell	state	Read or write a durable state cell, or settle a race between runs.

Integrations

Each action of a connector is a node of its own, typed <connector>.<action>. The actions of one connector share its with fields and its credential. Connectors covers credentials, connector versions and script actions. Google Sheets authenticates as a Google account a project member connected under Settings > Connections > Connected accounts; name that account as the step’s credential.

Matrix

Node	Kind	What it does
Send message	matrix.send_message	Posts a message to a Matrix room, as the account whose access token the credential holds.

Anthropic

Node	Kind	What it does
Create message	anthropic.messages	Sends one prompt to the Claude Messages API and returns the reply.

OpenAI-compatible chat

Node	Kind	What it does
Chat completion	openai-compatible.chat	Sends one prompt to any API that speaks OpenAI’s /chat/completions (OpenAI, Mistral, Ollama, vLLM, LM Studio, LiteLLM) and returns the reply.

Slack

Node	Kind	What it does
Post message	slack.post_message	Posts a message to a Slack channel, as the bot whose token the credential holds.

Telegram

Node	Kind	What it does
Send message	telegram.send_message	Sends a plain-text message to a Telegram chat, group or channel, as a bot.

GitHub

Node	Kind	What it does
Set commit status	github.set_commit_status	Sets a commit status on GitHub: the check with a pending, green or red mark beside a commit and on its pull request.
Report a run’s status	github.report_run_status	Turns a run’s lifecycle event into a GitHub commit status: run.started posts pending, run.succeeded success, run.failed failure and run.cancelled error.

Gitea / Forgejo

Node	Kind	What it does
Set commit status	gitea.set_commit_status	Sets a commit status on a Gitea or Forgejo server: the check mark beside a commit and on its pull request.
Report a run’s status	gitea.report_run_status	Turns a run’s lifecycle event into a commit status on Gitea or Forgejo: run.started posts pending, run.succeeded success, run.failed failure and run.cancelled error.

46elks

Node	Kind	What it does
Send SMS	46elks.send_sms	Sends a text message through 46elks, for the alert that has to reach someone who isn’t looking at a screen.
Send SMS (dry run, nothing sent)	46elks.send_sms_dryrun	Checks and prices a text message with 46elks without sending it.

Google Sheets

Node	Kind	What it does
Read rows as objects	google-sheets.read_rows	Reads the rows under a sheet’s header row as objects keyed by the header, a chunk at a time, however long the table is.
Append rows	google-sheets.append_rows	Adds rows below a sheet’s table, once, even when the step is retried.
Update or append a row by key	google-sheets.update_row_by_key	Finds the row whose key column holds a key and writes the given cells into it, or appends a new row when there is none.
Read range	google-sheets.read_range	Reads a block of cells in A1 notation and returns it as a list of rows, each a list of cells.
Update range	google-sheets.update_range	Writes a list of rows into a block of cells, starting at the range you give.
Clear range	google-sheets.clear_range	Empties a block of cells and keeps their formatting.
Get spreadsheet details	google-sheets.get_spreadsheet	Returns a spreadsheet’s title, locale and time zone, and each sheet’s properties: its title, id, position and size.
Create spreadsheet	google-sheets.create_spreadsheet	Creates a new spreadsheet in the connected account’s Drive and returns its id and address.
Add sheet	google-sheets.add_sheet	Adds a sheet (a tab) to an existing spreadsheet.

Fields every node takes

A node in a graph document is id, type and config, where config is what each page here lists. Beside config a node also takes:

• note: why the step is there
• if: a CEL condition; the node is skipped unless it is true
• continue_on_error: a failure is recorded and the run carries on
• retry, timeout, requires, agent: for nodes that run on an agent (http, shell, code, and every connector action)
• concurrency: a lease group, with {{ … }} holes

Values in config can be computed: { $expr: "<cel>" } keeps the value’s type and { $template: "text {{ cel }}" } builds a string. Both read nodes.<id>.output, input, vars and run.
