        "content": "Community Node Disclaimer: This workflow uses KlickTipp community nodes.\n\n## Introduction\nThis workflow creates a complete two-way synchronization between **KlickTipp** and **Google Calendar**.  \nWhen a contact in KlickTipp is tagged, an event is automatically created in Google Calendar.  \nIf event status changes or if attendees respond, their RSVP status and event status are reflected in KlickTipp \u2014 keeping your contact database, campaigns, and event insights always up to date.\n\nPerfect for marketers, coaches, or event organizers who want to automatically send event invites and instantly capture participation status without manual updates.\n\n## How it works\n### Google Calendar \u2192 KlickTipp:\nThis template keeps your KlickTipp list in sync with Google Calendar across the **full event lifecycle**.  \nFor every incoming event, the workflow follows these steps:\n\n1. **Watch Google Calendar events**\n   - Listens for:\n     - **Event Created**\n     - **Event Updated**\n     - **Event Cancelled**\n\n2. **Iterate through attendees**\n   - Each attendee is handled as a separate item.\n   - This ensures accurate contact updates and tagging even for large events or webinars.\n\n3. **Filter attendees (optional)**\n   - Attendees from internal or excluded email domains can be filtered out before any processing.\n\n4. **Check if the attendee already exists in KlickTipp**\n   - If the contact exists \u2192 update the contact.\n   - If the contact does not exist \u2192 subscribe the contact (with Single or Double Opt-In, depending on action).\n\n5. **Transfer event data to KlickTipp**\n   - Event details (summary, description, location, start and end time) are written into KlickTipp custom fields.\n   - Contacts always reflect the most recent event information.\n\n6. **Route by attendee response status**\n   - Attendees are routed based on their `responseStatus`:\n     - `needsAction` \u2192 contact was added to an event\n     - `accepted` \u2192 **event confirmed**\n     - `declined` \u2192 **event declined**\n     - `tentative` \u2192 **event considered**\n\n7. **Apply tags in KlickTipp**\n   - Based on event type and attendee status, the workflow applies the corresponding tags:\n     - Event created / updated\n     - Event canceled\n     - Event confirmed\n     - Event declined\n     - Event considered\n\n### KlickTipp \u2192 Google Calendar:\n- Watches for a tag like **\u201cSend an event invitation via Google Calendar\u201d**.\n- Creates an event in Google Calendar using mapped KlickTipp fields.\n\n## Setup Instructions\n1. **KlickTipp Preparation**\n      - Prepare **custom fields**\n       - `Google Calendar | event summary`, data type: \"Single line\"\n       - `Google Calendar | event description`, data type: \"Single line\"\n       - `Google Calendar | event location`, data type: \"Single line\"\n       - `Google Calendar | event start datetime`, data type: \"Datetime\"\n       - `Google Calendar | event end datetime`, data type: \"Datetime\" \n      - Prepare **tags**:\n       - `Google Calendar | event created/updated`\n       - `Google Calendar | event canceled`\n       - `Google Calendar | event declined`\n       - `Google Calendar | event confirmed`  \n       - `Google Calendar | event considered` \n       - `Send an event invitation via Google Calendar`\n      - Prepare **outbound**:\n       - **Activation tag:** `Send an event invitation via Google Calendar`\n       - **Activation URL:** webhook URL from trigger\n\n2. **Credential Configuration**\n     - Connect your Google Calendar account using **Client ID** and **Client Secret** from the Google Cloud.\n     - Authenticate your KlickTipp connection with **username/password** credentials (API access required).\n\n## Customization\n- Recommended poll frequency: every 1\u20135 minutes for near real-time updates.\n- Adjust to your local timezone if necessary.  \n- Each trigger works independently, allowing partial deployments if only certain event types are needed.  \n- Ensure **End > Start** in your data. If you prefer a fixed duration, compute End from Start + minutes in a Date & Time node.  \n- If you want a Meet link, enable \u201cAdd Google Meet video conferencing\u201d in the Calendar node instead of pasting a Calendar URL into Location."
