Automated Employee Onboarding System: From Offer Letter to Google Workspace
Automated Employee Onboarding System: From Offer Letter to Google Workspace📺 Watch the Video TutorialFor a visual walkthrough of this automation in action, check out the tutorial below:https://youtu.be/vX-0vv7OUXc🚀 Workflow OverviewThis n8n workflow creates a fully automated end-to-end recruitment and onboarding engine. It streamlines two critical phases of HR operations: Offer Letter Generation: Automatically generating and emailing a PDF offer letter when candidate data is received. Onboarding & Provisioning: Detecting candidate acceptance via email, provisioning a corporate Google Workspace account, and securely delivering credentials. ⚙️ Phase 1: Candidate Intake & Offer Letter GenerationTriggered via WebhookThis section handles the initial processing of a successful candidate.1. Data Ingestion & Formatting Webhook (POST): The workflow starts when candidate data (personal info, job details, bank info) is posted to the webhook URL. Edit Fields: Cleanups and extracts key data points (Full Name, Address, Job Title, Manager Name, etc.) to ensure they are ready for document generation. 2. Database Entry Google Sheets (Save Candidates Details): Acts as the "Employee DB". Records all candidate details including emergency contacts and bank info. Sets an initial status flag workplace_acc_created? to "no". 3. Document Generation PDFBro (Generate Offer Letter): Dynamically creates a PDF offer letter. Populates the template with the candidate's name, address, job title, department, and salary frequency. 4. Delivery Gmail (Send Offer Letter): Sends an email to the candidate's personal address. Attaches the generated PDF offer letter. Subject: "Offer Letter" | Body includes a congratulatory message. 🤖 Phase 2: Acceptance Verification & IT ProvisioningTriggered via Gmail PollingThis section runs periodically to check if the candidate has accepted the job offer.1. Intelligent Monitoring Gmail Trigger: Polls the HR inbox every minute for new emails. Google Sheets (Lookup): Checks if the sender's email exists in the "Employee DB". Filter: Ensures the workflow only proceeds if: The email is from a known candidate. The candidate has not yet been onboarded (workplace_acc_created? is not "yes"). 2. AI-Powered Analysis Google Gemini (AI Agent): Reads the email subject and body. Prompt: "Check if the mail is an acceptance of offer letter... respond with 'yes' if it is an acceptance." This eliminates false positives (e.g., a candidate asking a question about the salary isn't mistakenly onboarded). 3. Account Provisioning (If Accepted)If the AI confirms the email is an acceptance ("Yes"): JavaScript Code: Generates a secure, random 16-character temporary password (timestamp + random string). Google Workspace Admin (Create User): Creates a new internal email account (e.g., firstname.lastname@blankarray.com). Sets the temporary password. Security: Forces the user to change their password upon first login (changePasswordAtNextLogin: true). 4. Credential Delivery & Sync Gmail (Send Credentials): Sends a beautifully formatted HTML email to the new employee's personal address. Contains their new Work Email and Temporary Password. Includes a "Log In to Workplace" button. Google Sheets (Update Status): Updates the candidate's row in the DB. Sets workplace_acc_created? to "yes" to prevent duplicate account creation in the future. 🛠️ Prerequisites & Credentials NeededTo use this workflow, you will need to configure the following credentials in n8n: Google Workspace Admin: For creating users (requires Admin SDK API access). Google Gemini (PaLM) API: For the AI analysis of emails. Google Drive/Sheets: Service account access to read/write the Employee DB. Gmail (OAuth2): To read incoming replies and send outgoing emails. PDFBro: API key for generating the PDF documents.
