Every workflow run starts with a trigger. A trigger is the entry point of your workflow: when it fires, NoClick executes the nodes connected downstream of it. A workflow can hold more than one trigger, and each fires independently.
Trigger types
Where to see what triggered a run
Every run records its trigger source. Open the Logs tab in the canvas top bar: each row shows the source (Manual, Schedule, Webhook, Email, Form, or API) along with status, duration, and any error message. See Execution logs.
To pause a trigger without deleting it, disable the trigger node. Incoming events are acknowledged but the workflow does not run until you re-enable it.
Triggers and AI agents
A trigger wired directly into an AI agent delivers the fired event as part of the agent’s turn, so the agent can read a Slack message or an email and act on it. See Channel agents.
