## Configure the Tool node

Select the node to open the **Tool** panel. Complete the steps in order:

1. **Select App** — Search the app catalog and pick an app.
2. **Select Function** — Choose the action to run. This step unlocks after you pick an app.
3. **Linked Account** — Connect or choose the account the step should use.

Then fill in the function inputs. Use **Insert Variable** to pass values from earlier steps, or expand **Raw JSON** when you need the payload as JSON.

Manage which apps are available in **Admin** → **Tools**. See [Tools Overview](/tools/overview).
