When candidate and position details are submitted via webhook, the system first verifies the candidate's email address using VerifiEmail to ensure deliverability and prevent bounced emails. Valid submissions proceed to data preparation where salary formatting, joining dates, and company details are structured. OpenAI GPT-4 then generates a professional, personalized offer letter body that's warm yet formal, highlighting the role, responsibilities, compensation, and company culture. The AI-generated content is merged with candidate details and formatted into a beautifully designed HTML document complete with company branding, styled headers, position details tables, and an SVG-based digital signature. This HTML is converted to a professional PDF that's immediately emailed to the candidate with clear next steps for acceptance. Simultaneously, the HR team receives a Slack notification with key offer details and document tracking information, ensuring internal visibility and follow-up capability.\n\n### Setup Steps\n1. Connect required credentials: OpenAI API, VerifiEmail, HTML-to-PDF service, Gmail, and Slack.\n2. Update company branding in the HTML generation node: company name, colors, logo, address, and contact details.\n3. Customize the HR signature section with your HR manager's name and title.\n4. Configure the Slack channel where offer notifications should be sent.\n5. Adjust the OpenAI prompt to match your company's tone and industry-specific requirements.\n6. Copy the webhook URL and integrate it into your HR management system or applicant tracking software.\n7. Test with sample candidate data to verify email delivery and PDF formatting.\n\n### Customization\n- Modify the AI system prompt to emphasize specific company values or culture points.\n- Adjust HTML styling and colors to match your corporate branding guidelines.\n- Add additional position details fields in the details box (benefits, bonus structure, equity, etc.).\n- Customize the email template styling and messaging to align with your employer brand." }, "typeVersion": 1 }, { "id": "55c6eea1-4d5d-4aa5-a2a6-851b5dd696c5", "name": "Sticky Note2", "type": "n8n-nodes-base.stickyNote", "position": [ -1632, 288 ], "parameters": { "color": 7, "width": 560, "height": 272, "content": "## Input & Email Verification\nReceives candidate details via webhook and verifies email deliverability before processing." }, "typeVersion": 1 }, { "id": "f9379482-94c4-4d9a-a61d-ba90a63845b1", "name": "Sticky Note3", "type": "n8n-nodes-base.stickyNote", "position": [ -976, 240 ], "parameters": { "color": 7, "width": 496, "height": 304, "content": "## Data Preparation & AI Generation\nStructures candidate data and uses OpenAI to generate a professional, personalized offer letter." }, "typeVersion": 1 }, { "id": "9029b224-7925-4b29-9d31-7e6c1a8be79a", "name": "Sticky Note4", "type": "n8n-nodes-base.stickyNote", "position": [ -432, 256 ], "parameters": { "color": 7, "width": 448, "height": 256, "content": "## Document Formatting & Conversion\nBuilds branded HTML offer letter with digital signature and converts it to PDF format." }, "typeVersion": 1 }, { "id": "6cdc665c-7348-4e09-a1d1-51cfaf0fb70c", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [ 80, 240 ], "parameters": { "color": 7, "width": 384, "height": 288, "content": "## Delivery & Notifications\nEmails PDF to candidate and sends confirmation notification to HR team via Slack." }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId": "", "connections": { "Webhook": { "main": [ [ { "node": "Email Verification", "type": "main", "index": 0 } ] ] }, "Convert to PDF": { "main": [ [ { "node": "Deliver Offer Letter", "type": "main", "index": 0 } ] ] }, "Notify HR Team": { "main": [ [] ] }, "Email Verification": { "main": [ [ { "node": "Check Email Validity", "type": "main", "index": 0 } ] ] }, "Prepare Offer Data": { "main": [ [ { "node": "Generate Offer Letter Content", "type": "main", "index": 0 } ] ] }, "Check Email Validity": { "main": [ [ { "node": "Prepare Offer Data", "type": "main", "index": 0 } ] ] }, "Deliver Offer Letter": { "main": [ [ { "node": "Notify HR Team", "type": "main", "index": 0 } ] ] }, "Build HTML with SVG Signature": { "main": [ [ { "node": "Convert to PDF", "type": "main", "index": 0 } ] ] }, "Generate Offer Letter Content": { "main": [ [ { "node": "Build HTML with SVG Signature", "type": "main", "index": 0 } ] ] } } }
