1.1 Workflow description

Title: Automated email support triage with GPT-4, Gmail & Trello
Workflow name: Automated email support triage with GPT-4, Gmail & Trello

How It Works ⚙️

This workflow is a comprehensive, AI-powered system that acts as a virtual support manager. It automates the entire process of handling incoming support tickets, ensuring speed, accuracy, and efficiency.

Ticket Ingestion: The workflow starts when a new email arrives in your support inbox via the Gmail Trigger.
AI Analysis & Triage: An OpenAI node acts as an intelligent agent, instantly analyzing the email to categorize the issue, assign a priority, and determine the customer's sentiment (e.g., "Angry," "Neutral").
Proactive Escalation: The workflow uses an If node to check for "Critical" priority or "Angry" sentiment. If these conditions are met, it takes a separate path to notify a manager immediately.
Ticket Creation: Regardless of urgency, a Trello card is created for the ticket, including all the AI's analysis and the original email content.
Automated Response: For low-priority tickets, a second If node and a Gmail node can send an automated, AI-generated response, completely freeing up your team.
Performance Reporting: All ticket data, including the AI's analysis, is logged to a Google Sheets dashboard for real-time analytics and to track support trends.

How to Set Up 🛠️

Track post-therapy wellness with GPT-4o-mini, Telegram, Slack and Sheets

## Quick Overview This workflow uses Google Sheets, OpenAI, Telegram, and Slack to send post-therapy check-in messages, analyze patient replies for sentiment and risk, alert therapists to at-risk responses, and log non-urgent replies for ongoing wellness tracking. ## How it works 1. Runs every hour on a schedule trigger. 2. Reads session records from Google Sheets and keeps only sessions that have a session date and have not been marked as check-in sent. 3. Uses OpenAI (gpt-4o-mini) to generate a personalized, non-clinical Telegram check-in message from the patient’s session details. 4. Sends the check-in to the patient via Telegram and updates the Google Sheets session row to store the message and mark the check-in as sent. 5. Triggers on incoming Telegram messages, looks up the patient in a Google Sheets master list by Telegram ID, and selects the most relevant recent session to provide context. 6. Sends the patient reply and session context to OpenAI for JSON-formatted sentiment classification and parses the result into structured fields. 7. If the sentiment is classified as at-risk, posts an urgent alert to a Slack channel; otherwise, appends the reply and sentiment details to a Google Sheets wellness log. ## Setup 1. Connect Google Sheets OAuth credentials and update the spreadsheet document ID and sheet names for Sessions, Patients_Master, and Wellness_Log. 2. Create and connect a Telegram bot credential, set up the Telegram trigger webhook, and ensure patient Telegram chat IDs are stored in Google Sheets. 3. Add an OpenAI API key credential and confirm the selected model (gpt-4o-mini) meets your requirements. 4. Connect Slack OAuth credentials and replace the placeholder Slack channel ID used for therapist alerts, and confirm the error-alert channel is set correctly. 5. Verify your Google Sheets columns match the workflow’s expected fields (for example session_id, checkin_sent, checkin_message_sent, therapist_slack_id) before activating.

Detect and route customer escalations with Claude, Slack and Linear

## Quick Overview This workflow receives support messages via a webhook, normalizes payloads from Gmail, Zendesk, Intercom, and HelpScout, and uses Anthropic Claude to detect escalation signals and severity, then posts alerts to Slack and creates Linear tickets for actionable cases. ## How it works 1. Receives an inbound support message via a POST webhook. 2. Normalizes the incoming payload (Gmail, Zendesk, Intercom, HelpScout, or a raw test payload) into a consistent schema with customer details, subject, body text, and a source URL. 3. Sends the normalized message to Anthropic Claude and parses the response into structured JSON containing escalation flags, severity, trigger phrases, a summary, and a suggested reply opening. 4. Stops processing silently when the message is not an escalation (severity is none). 5. Builds a formatted Slack alert and Linear issue payload, including SLA guidance, detected signals, and links back to the original conversation. 6. Posts the escalation alert to a configured Slack channel. 7. Creates a Linear ticket for critical, high, and medium severity escalations and sends a Slack DM to a manager for critical and high cases. ## Setup 1. Add an Anthropic API credential for the Anthropic Chat Model node. 2. Add a Slack OAuth2 credential, set the target channel (for example, #escalations), and set the manager’s Slack user ID for direct messages. 3. Add a Linear OAuth2 credential and replace the placeholder Linear team ID used when creating tickets. 4. Copy the webhook URL from the webhook trigger and configure Gmail/Zendesk/Intercom/HelpScout (or your custom source) to POST message payloads to it in one of the supported formats.

Triage construction incidents with GPT-4o, Slack, Gmail and Google Sheets

## Quick Overview This workflow ingests construction incident webhooks, normalizes the payload, and uses OpenAI GPT-4o-mini to classify each incident by type and urgency, then routes alerts to Slack and Gmail and logs incidents to Google Sheets, with a daily Slack digest generated from the sheet. ## How it works 1. Receives an incoming incident via a POST webhook. 2. Normalizes the incoming Procore/Fieldwire-style payload into a consistent incident object (ID, title, description, location, reporter, assignee, and timestamps). 3. Sends the incident details to OpenAI (GPT-4o-mini) to classify issue type and urgency and generate a short summary, recommended action, and tags. 4. Routes incidents by urgency, sending Critical incidents to Slack with an @channel mention and emailing details to a project manager via Gmail. 5. Sends High-urgency incidents to Slack as a formatted notice. 6. Appends every incident to a Google Sheets log with status set to open. 7. Runs daily at 18:00 server time, reads the incident log from Google Sheets, builds an urgency-grouped digest, and posts it to a Slack channel. ## Setup 1. Add credentials for OpenAI, Slack (OAuth2), Gmail (OAuth2), and Google Sheets (OAuth2). 2. Copy the webhook URL from the Webhook trigger and register it in your source system (for example, Procore or Fieldwire) as the incident-created endpoint. 3. Replace the placeholder Slack channel IDs for Critical, High, Digest, and Error alerts. 4. Update the Gmail recipient address ([email protected]) to your real project manager email. 5. Set the Google Sheets spreadsheet (document ID) and ensure the target sheet exists with columns that match the incident log fields used by the workflow. 6. Confirm the schedule trigger time (cron: 0 18 * * *) matches your desired timezone/server time for the daily digest.
