A built-in error alert flags any failed run.\n\n**Perfect for:** real estate agents and brokerage teams.\n\n---\n\n## How it works\n\n1. **New Property Inquiry** \u2014 webhook that receives the website inquiry form.\n2. **Structure Lead** \u2014 organizes name, email, phone, property, message, source, and submission time.\n3. **Validate Lead Input** \u2014 checks that name, a valid email, and a phone number are present.\n4. **Format Rejection Reason** / **Reject Inquiry** \u2014 *(invalid path)* returns a clear 400 error to your site explaining what's missing.\n5. **Normalize Lead Data** \u2014 lowercases the email and strips formatting from the phone number.\n6. **Classify Lead Interest** \u2014 scans the message and property for keywords (luxury, urgent, cash buyer) to flag hot leads.\n7. **Upsert Lead in CRM Sheet** \u2014 appends a new row, or updates the existing row, matched on email, so a repeat inquiry never creates a duplicate.\n8. **Is High Priority Lead** \u2014 branches based on the priority flag.\n9. **Send Priority Auto Reply** / **Notify Senior Agent** \u2014 *(high priority path)* faster-turnaround email and a senior agent Slack alert.\n10. **Send Auto Reply to Lead** / **Notify Agent Team** \u2014 *(standard path)* the regular acknowledgement email and team alert.\n11. **Merge Notification Branches** \u2014 waits for whichever path ran, then continues once.\n12. **Confirm Inquiry** \u2014 returns a success response to the website.\n13. **Workflow Error Trigger** / **Alert Team on Workflow Failure** \u2014 *(error path)* posts to Slack if any step in this workflow throws an error.\n\n---\n\n## Setup (~15 min)\n\n1. **Webhook** \u2014 connect your site form to the *New Property Inquiry* URL.\n2. **Google Sheets** \u2014 connect your account and your own CRM sheet id in *Upsert Lead in CRM Sheet*; add Email, Name, Phone, Property, Message, Source, Priority, Submitted At as column headers.\n3. **Gmail** \u2014 connect Gmail in *Send Auto Reply to Lead* and *Send Priority Auto Reply*, and edit the wording.\n4. **Slack** \u2014 connect Slack and set the channels in *Notify Agent Team*, *Notify Senior Agent*, and *Alert Team on Workflow Failure*.\n> Replace the placeholder sheet id and channel ids below with your own before publishing \u2014 never submit a template with a real personal spreadsheet id or channel id."
