# App events

> Start workflow runs from native events in connected services like Slack, HubSpot, GitHub, and Google Drive.

Many integration nodes can act as triggers. Instead of performing an action, the node listens for an event in the connected service (a new Slack message, a HubSpot contact, a GitHub push) and starts a run each time one arrives.

## Select a trigger operation

<Steps>
  <Step title="Add the integration node">
    Add the service's node (for example **Slack**) and connect your credential.
  </Step>

  <Step title="Pick a trigger operation">
    Open the node's operation picker. Trigger operations are grouped under **Triggers** at the top of the list. Select one, such as **On Channel Message**.
  </Step>

  <Step title="Configure and connect">
    Fill in any event filters (for example, which channel or repository to watch) and connect the node to your downstream steps. NoClick registers the event subscription with the provider automatically, and the workflow runs on each matching event.
  </Step>
</Steps>

**Instant push** events arrive via webhook subscriptions that NoClick creates for you. Google Drive, Google Calendar, and Jira subscriptions expire periodically and are renewed automatically. **Scheduled poll** triggers cover services without a usable push API: you pick a schedule on the node (default: every 5 minutes) and each poll fires the workflow only for items it has not seen before. A poll that finds no new items runs nothing downstream, so connected nodes and AI agents stay idle until there is something new.

<Note>
  Most subscriptions register automatically. Two exceptions show a webhook URL on the node to paste into the provider yourself: Resend (add it as an endpoint at resend.com/webhooks) and WhatsApp Cloud API credentials (configure it in the Meta Developer Console; QR-paired WhatsApp registers automatically).
</Note>

## App events and AI agents

Wire the trigger node directly into an AI agent and each event is delivered as part of the agent's turn. One node cannot both fire runs and provide agent tools: to build an agent that listens and replies in the same service, use two nodes, one with the trigger operation and one wired in as a tool provider. See [Channel agents](/agents/channel-agents).
