Manage employee offboarding with Google Workspace, Slack, HubSpot and Notion

## Quick Overview This workflow receives an HR offboarding webhook, validates and enriches the employee record, suspends the user in Google Workspace, deactivates the user in Slack, looks up the matching HubSpot contact, logs the event to Notion and Google Sheets, and notifies HR/IT via Gmail and Slack. ## How it works 1. Receives a POST webhook from the HR system with employee offboarding details. 2. Parses the payload to normalize key fields (name, email, department, manager, last day) and flags invalid requests. 3. Posts an alert to a Slack IT channel when the record is invalid and stops further processing. 4. Enriches valid records with an offboarding ID, risk level, revocation deadline, and an actions summary. 5. Suspends the employee in Google Workspace via the Admin Directory API, deactivates the user in Slack via the Slack API, searches for the contact in HubSpot, and creates an offboarding entry in a Notion database. 6. Combines the revocation results and appends a compliance log row to a Google Sheets “Offboarding Log” tracker. 7. Emails an offboarding completion summary to the manager and HR using Gmail and posts a completion digest to the Slack IT channel. ## Setup 1. Copy the n8n webhook URL from the HR offboarding webhook trigger and configure your HR system to POST the offboarding payload to it. 2. Provide credentials/tokens for the Google Admin Directory API and Slack API (both used via HTTP requests) and replace the placeholder Bearer tokens in the request headers. 3. Add a HubSpot App Token credential with access to search contacts. 4. Create a Notion database for offboarding logs, add a Notion API integration, and set the Notion database ID and API key in the Notion request. 5. Add Google Sheets OAuth credentials, set your Google Sheet ID, and ensure the “Offboarding Log” sheet contains the columns mapped in the append step. 6. Add a Gmail connection for sending summary emails and set the target Slack channel ID for the invalid-record alert and IT ops digest messages.

Send AI interview briefs from resumes with GPT-4o-mini, Google Sheets and Gmail

## Quick Overview This workflow runs every 15 minutes to read candidate rows from Google Sheets, download each resume PDF from Google Drive, extract text, generate an HTML interview brief using OpenAI GPT-4o-mini, email it via Gmail to the interviewer, and mark the row as Processed to avoid duplicates. ## How it works 1. Runs on a schedule trigger every 15 minutes. 2. Reads all candidate rows from the “Candidates” tab in Google Sheets and processes them one at a time. 3. Skips any rows where the Status column is already set to “Processed.” 4. Extracts the Google Drive file ID from the resume link, downloads the PDF, and converts it to plain text. 5. Cleans and truncates the resume text and combines it with the candidate’s name, role, and email details. 6. Sends the resume text and metadata to OpenAI (GPT-4o-mini) to generate a styled HTML interviewer brief. 7. Emails the HTML brief to the interviewer via Gmail and updates the candidate row in Google Sheets to “Processed,” then waits 5 seconds before moving to the next candidate. ## Setup 1. Add Google Sheets OAuth credentials and replace `YOUR_CANDIDATES_SHEET_ID`, then create a “Candidates” sheet with columns Name, Email, Job Role, Resume Drive Link, Interviewer Email, and Status. 2. Add Google Drive OAuth credentials and ensure each resume PDF is accessible to the workflow (for example, shared so the connected account can view it). 3. Add an OpenAI API credential and keep the model set to GPT-4o-mini. 4. Add Gmail OAuth credentials and confirm the sender name and subject line meet your email requirements. 5. Adjust the schedule interval if you want the workflow to check for new candidates more or less frequently.

Provision new hire IT accounts with Google Workspace, Slack, and Gmail

## Quick Overview This workflow receives new-hire records via a webhook, validates and normalizes the data, then provisions a Google Workspace account, creates an onboarding task in Google Tasks, notifies the IT team in Slack, emails the hiring manager via Gmail, and logs the run to Google Sheets. ## How it works 1. Receives a new hire payload from the HR system through an HTTP webhook endpoint. 2. Parses the payload, standardizes key fields (name, department, manager, start date), and skips records missing required identity data. 3. If the record is invalid, posts a Slack message to the IT channel for manual review and stops processing. 4. For valid hires, generates a company email address, username, temporary password, ticket title, and a target ready-by date. 5. Creates the new user in the Google Admin Directory (Google Workspace) and opens an IT onboarding checklist as a Google Tasks task. 6. Posts a provisioning summary to the IT Slack channel, emails the manager a day-one checklist via Gmail, and appends the provisioning details to a Google Sheets log. ## Setup 1. Configure your HR system (or source app) to send a POST request to the workflow webhook path `/hr/new-hire` using the production webhook URL. 2. Add Google credentials with access to the Admin SDK Directory API (for user creation), Google Tasks, Gmail, and Google Sheets, and ensure the account has the required admin permissions. 3. Add Slack credentials, set the target channel ID for IT onboarding notifications, and update the channel selection if needed. 4. Update the email domain in the generated address (currently `@yourcompany.com`) and confirm how departments map to Google Workspace org unit paths. 5. Set your Google Sheets document ID and ensure it contains (or can create) a sheet named "Provisioning Log" with matching columns for the appended fields.
