the full lifecycle of a training certificate. \n`/certifications` receives learner details, generates a unique CertificationID and checks that it does not exist yet. \nIf the ID is free, the workflow stores the record, builds a PDF certificate and emails it to the learner. \n\n`/certificationscheck` lets you verify a certificate later. \nThe webhook receives a CertificationID, looks it up in the same Data Table and returns a simple JSON response that frontends or other services can use to show \u201cvalid\u201d or \u201cnot found\u201d.\n\n## Setup steps\n1. Create a Data Table (e.g. **Certifications**) with Name, Surname, CertificationID and any extra fields.\n2. Configure the PDF Generator node with your account API and adjust the HTML template to your branding.\n3. Connect your email account (Gmail/SMTP) in **Email_Certification**.\n4. Deploy the `/certifications` and `/certificationscheck` webhooks and use their public URLs.\n5. Test creation and verification with a few sample requests before going live.\n" }, "typeVersion": 1 }, { "id": "33d6d124-643b-4cb5-b7bc-a78266aaefec", "name": "Generate a PDF document", "type": "@pdfgeneratorapi/n8n-nodes-pdf-generator-api.pdfGeneratorApi", "position": [ 544, -224 ], "parameters": { "data": "={\n \"DueDate\": \"{{$now.toISODate()}}\",\n \"Candidate\": \"{{$('Webhook_Creation').item.json.headers.name}} {{$('Webhook_Creation').item.json.headers.surname}}\",\n \"CourseName\": \"{{ $('Webhook_Creation').item.json.headers.course }}\",\n \"ID\": \"{{ $('Generate_Certification_ID').item.json.id }}\"\n}", "templateId": { "__rl": true, "mode": "list", "value": "1560735", "cachedResultName": "Certificate Example (ID: 1560735)" }, "documentOutput": "file", "additionalFields": {} }, "credentials": { "pdfGeneratorApi": { "name": "" } }, "typeVersion": 1 } ], "active": true, "settings": { "executionOrder": "v1" }, "versionId": "27c846c4-3476-4aaa-b81d-19c93a130da0", "connections": { "Webhook_Check": { "main": [ [ { "node": "Find_Certification_By_ID1", "type": "main", "index": 0 } ] ] }, "Webhook_Creation": { "main": [ [ { "node": "Generate_Certification_ID", "type": "main", "index": 0 } ] ] }, "Insert_Certificaton": { "main": [ [ { "node": "Generate a PDF document", "type": "main", "index": 0 } ] ] }, "Certification_Exists": { "main": [ [ { "node": "Respond_Found", "type": "main", "index": 0 } ], [ { "node": "Respond_NotFound", "type": "main", "index": 0 } ] ] }, "Certification_ID_Exists": { "main": [ [ { "node": "Generate_Certification_ID", "type": "main", "index": 0 } ], [ { "node": "Insert_Certificaton", "type": "main", "index": 0 } ] ] }, "Generate a PDF document": { "main": [ [ { "node": "Email_Certification", "type": "main", "index": 0 } ] ] }, "Find_Certification_By_ID": { "main": [ [ { "node": "Certification_ID_Exists", "type": "main", "index": 0 } ] ] }, "Find_Certification_By_ID1": { "main": [ [ { "node": "Certification_Exists", "type": "main", "index": 0 } ] ] }, "Generate_Certification_ID": { "main": [ [ { "node": "Find_Certification_By_ID", "type": "main", "index": 0 } ] ] } } }
