"content": "# \ud83d\udcc5 Email-to-Calendar: Auto-Extract Events from Confirmation Emails with easybits\n\n## What This Workflow Does\nForward any confirmation email \u2013 flight bookings, hotel reservations, restaurant bookings, doctor appointments, package deliveries, event tickets \u2013 to a labeled inbox, and it automatically becomes a calendar event with all the details (date, time, location, confirmation number, vendor) attached.\n\nOne universal pipeline handles every vendor format. No per-airline, per-hotel, per-restaurant parsing logic. The **easybits Extractor** reads the email body and any PDF attachments, pulls out the structured event data, and Google Calendar takes care of the rest.\n\n## How It Works\n1. **Gmail Trigger** \u2013 Polls Gmail for messages with your chosen label (e.g. `Events`)\n2. **Dual Extraction** \u2013 Email body is rendered to PDF and extracted; PDF/image attachments are extracted in parallel\n3. **Merge** \u2013 Combines both extractions; attachment data wins over body data (attachments are authoritative)\n4. **Validation Gate** \u2013 Confirms a real event was extracted (date + type present)\n5. **Calendar Event** \u2013 Creates the event in your dedicated `Auto-imported` calendar\n6. **Review Path** \u2013 Non-confirmation emails get a `Needs-Review` label + email notification listing missing fields\n\n---\n\n## Setup Guide\n\n### 1. Create Your easybits Extractor Pipeline\n1. Go to [extractor.easybits.tech](https://extractor.easybits.tech), sign up, and click **\"Create a Pipeline\"** on your dashboard\n2. Fill in the **Pipeline Name** (e.g. \"Event Calendar\") and **Description**\n3. Upload a **sample confirmation email PDF** as your reference (a flight or hotel booking works well)\n4. Click **\"Auto-Mapping\"** \u2013 the Extractor analyzes your sample and suggests fields automatically\n5. Adjust the suggested fields to match the 9 fields used by this workflow (see field list below)\n6. Click **\"Save & Test Pipeline\"** to verify extraction works\n7. Go to **Pipeline Details \u2192 View Pipeline** and copy your **Pipeline ID** and **API Key**\n\n**Required fields** (all string type, all should return `null` when missing):\n- `event_type` \u2013 flight / hotel / restaurant / appointment / delivery / event / other\n- `title` \u2013 short event summary, max 60 chars\n- `start_datetime` \u2013 ISO 8601 with timezone offset\n- `end_datetime` \u2013 ISO 8601 with timezone offset\n- `location` \u2013 full address or venue name\n- `confirmation_number` \u2013 booking reference / PNR / order number\n- `vendor` \u2013 company or service provider\n- `notes` \u2013 vendor-specific details (seat, table size, room type)\n- `participants` \u2013 passenger names, party size, attendees\n\n> \ud83d\udca1 **Tip:** The more specific your field descriptions are, the more accurate your results will be \u2013 treat them like code.\n\n### 2. Install the easybits Extractor Node\n1. The node is **verified** and works on n8n Cloud out of the box \u2013 just search for \"easybits Extractor\" in the node panel\n2. For self-hosted instances, go to **Settings \u2192 Community Nodes \u2192 Install** and enter `@easybits/n8n-nodes-extractor`\n\n### 3. Connect Your Accounts\n1. **Gmail** \u2013 connect via OAuth2 for the Gmail Trigger and the three Gmail action nodes\n2. **Google Calendar** \u2013 connect via OAuth2 for the Calendar: Create Event node\n3. **easybits Extractor** \u2013 paste your Pipeline ID and API Key into both Extractor nodes\n\n### 4. Configure Gmail Labels\n1. In Gmail, create a label named `Events` \u2013 this is what the trigger watches for\n2. Create a nested label `Events/Needs-Review` \u2013 emails that fail validation get moved here\n3. In n8n, select these labels in the Gmail Trigger, Flag for Review, and Remove Events Label nodes\n\n### 5. Set Up the Auto-Imported Calendar\n1. Go to [calendar.google.com](https://calendar.google.com) \u2192 \"Other calendars\" \u2192 **+** \u2192 Create new calendar\n2. Name it `Auto-imported` (or your choice) and save\n3. In the Calendar: Create Event node, select this calendar from the dropdown\n\n### 6. Activate & Test\n1. Click **Active** in the top-right corner of n8n\n2. Apply the `Events` label to any confirmation email in Gmail\n3. Within a minute, check your `Auto-imported` calendar \u2013 the event should appear with full details\n4. The `Events` label is automatically removed after processing to prevent duplicates"
