Schedule

input.schedule Input v0.1.0

Fires on a cron schedule or fixed interval, emitting a tick with the fire time.

Finding it in the library

Search the builder's node library for Schedule (it lives under Input). A single click opens the in-editor docs panel shown here — description, ports, and every property, without leaving the canvas. Double-click (or drag) to add it to the workflow.

Wired up in the builder

Schedule in a real, runnable flow — captured live from the Studio editor, exactly as it looks on your canvas. This is the same workflow used for the example input & output below.

How it’s configured

The node’s Configure panel as it opens in the builder when you select the step — every setting laid out with real values. Click any field to edit it.

Ports

This is a trigger — it starts runs and takes no input wire.

Ports are the node’s contract with its neighbours. In the editor a port label renders bold when wired and italic when optional; ◈ ports accept attachment carriers rather than data wires.

How data flows through it

As a trigger, Schedule starts runs — it takes no input wire. What it emits is the request wrapper: the event’s body becomes the payload, and the wrapper carries the event metadata around it (for an HTTP-style trigger that’s headers.*, request.method, request.path and query). Downstream nodes consume the content — the wrapper is unwrapped at each node boundary, and expression roots like {{ headers.x }} still resolve against the wrapper when you need the metadata. See Runs & run data for the envelope model.

Expressions in the config

String-typed properties accept {{ }} expressions evaluated against the incoming item at run time — e.g. {{ $json.customer.email }}. On this node that’s timezone. JSON- and code-typed fields never interpolate — they are passed through literally.

Build it with AI

Every node in this reference is reachable through Flowdrome’s AI Copilot and the MCP tools — say what you want, and the graph surgery happens server-side. Node types resolve fuzzily, so the catalog label (Schedule) works as well as the exact type id (input.schedule).

In the Copilot panel (or any connected AI):

create a workflow that starts with schedule and logs the result

As a step in a create_chain_workflow call:

{"type":"Schedule","config":{}}

Raw MCP call — add this node to a workflow with add_node

curl -s -X POST http://localhost:48170/mcp -H "content-type: application/json" -d '{ "jsonrpc": "2.0", "id": "1", "method": "tools/call", "params": { "name": "add_node", "arguments": { "workflowId": "<id>", "type": "Schedule" } } }'

Example input & output

Captured from a real test run of the workflow above — this is what you see in the run data panel after pressing Test workflow.

Input — what the node received

{
  "tick": 1
}

Output — what the node produced

{
  "triggeredAt": "2026-07-17T04:29:26.236Z",
  "schedule": {
    "mode": "interval",
    "timezone": "UTC",
    "intervalSeconds": 60
  }
}

Property reference

Every setting, with its type and default — the same fields shown configured in the panel above.

Property	Type	Default	Description
Trigger on `mode`	`select`	`"cron"`	Fire the workflow on a cron schedule, or on a fixed repeating interval. `croninterval`
Cron expression `cron`	`cron`	`"0 9 * * *"`	Standard 5-field cron — minute, hour, day-of-month, month, day-of-week — evaluated in the timezone below. Shown when `(mode ?? "cron") !== "interval"`
Run every (seconds) `intervalSeconds`	`int`	`60`	How often to fire, in seconds. Minimum 1. Shown when `(mode ?? "cron") === "interval"`
Timezone `timezone`	`string`	`"UTC"`	IANA timezone the schedule is evaluated in (e.g. UTC, America/New_York).

Using it

Poll a feed every minute (the shipped RSS Digest demo)

Mode = interval, Interval seconds = 60. Feed it into RSS Read with Only new items on — schedule + RSS’s seen-item dedupe is the standard poller pattern: each tick emits only items it hasn’t seen before.

Every weekday at 9am, New York time

Mode = cron, Cron = 0 9 * * 1-5, Timezone = America/New_York.

Standard 5-field cron — minute, hour, day-of-month, month, day-of-week — evaluated in the configured IANA timezone. The editor’s cron field validates the expression live and shows the next firing times as you type.

Tips

In the editor, a schedule doesn’t tick on its own — Test workflow fires it once so you can develop without waiting for 9am. Deployed apps run the schedule for real, per the production trigger model.
Timezone matters twice a year: 0 9 * * * in America/New_York stays 9am local through DST; the same cron in UTC shifts an hour.
For run-once batch jobs triggered by an external scheduler (cron, CI), use the Manual trigger and job mode instead — the app executes once and exits.
