Add a event to Google Calendar automatically

1. Open template #427 on n8n.io and click Use for free, or copy the template JSON and paste it onto an empty canvas in n8n.
2. Create a credential under Credentials → Add credential: Google Calendar. Then open each of those nodes and pick the credential.
3. Click Execute workflow and step through each node's output to confirm the data looks right.
4. Toggle the workflow to Active so its trigger runs on its own.

Help me set up the n8n workflow "Add a event to Google Calendar automatically" (https://n8n.io/workflows/427). It uses: Google Calendar. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.

Paste into Claude Code and it will do the rest.
