CEU Certificate Generation & Distribution Workflow Setup Guide
What This Agent Does
This powerful automation workflow streamlines the entire process of generating, validating, and distributing Continuing Education Unit (CEU) certificates to course participants. When triggered by a webhook request, it validates participant data, verifies email addresses, generates personalized certificates with unique QR codes, and automatically distributes them via email while notifying your team.
Key benefits and time savings:
-
Eliminate manual certificate creation – Generate professional certificates in seconds instead of hours
-
Ensure data quality – Automatically validate emails before sending, reducing bounce rates and failed deliveries
-
Create audit trails – Log all certificate issuances to Google Sheets for compliance and record-keeping
-
Keep teams informed – Notify organizers via Slack in real-time when certificates are generated
-
Personalization at scale – Each certificate includes unique identifiers and QR codes for verification

sheet_url parameter
- Ensure the service account has Editor access to the sheet
- Map workflow data fields to corresponding sheet columns
Configuration Steps
Node-by-Node Configuration Guidance
1. Webhook Trigger (trigger.webhook)
- This is your entry point – no configuration needed
- TaskAGI automatically generates a unique webhook URL
- Copy this URL to your course platform or application
- The webhook accepts POST requests with participant data
2. Validate Required Fields (core.if_condition)
-
Purpose: Ensures all necessary data is present before processing
-
Configure: Check for required fields:
email, courseTitle, participantName
-
Condition example:
email != null AND courseTitle != null AND participantName != null
-
True path: Continues to email validation
-
False path: Triggers error response
3. Stop: Incomplete Data (core.respondToWebhook)
-
Purpose: Returns error message if validation fails
-
Body:
{"success": false, "error": "Missing required fields"}
-
HTTP Status: 400 (Bad Request)
- No additional configuration needed
4. Validate Email (zerobounce.validateEmail)
-
Purpose: Checks email validity using ZeroBounce API
-
Input: Email address from webhook payload
-
Output: Validation status (valid, invalid, catch-all, etc.)
- No manual configuration – uses your ZeroBounce integration
5. Check Email Valid (core.if_condition)
-
Purpose: Routes based on email validation result
-
Condition:
nodes.4.data.status == "valid"
-
True path: Proceeds to certificate generation
-
False path: Triggers invalid email error
6. Stop: Invalid Email (core.respondToWebhook)
-
Purpose: Returns error if email validation fails
-
Body:
{"success": false, "error": "Invalid email address"}
-
HTTP Status: 400
- No additional configuration needed
7. Generate Certificate ID & QR (core.function)
-
Purpose: Creates unique certificate identifier and QR code
-
Function logic:
- Generate UUID:
certificateId = generateUUID()
- Create QR data:
qrCode = generateQR(certificateId)
- Include timestamp:
issuedDate = getCurrentDate()
-
Output variables:
certificateId, qrCode, issuedDate
- These values are used in the certificate image
8. Create Certificate Image (htmlcsstoimage.createImage)
-
Purpose: Converts HTML certificate template to image
-
HTML template includes:
- Participant name:
[[nodes.1.data.participantName]]
- Course title:
[[nodes.1.data.courseTitle]]
- Certificate ID:
[[nodes.7.data.certificateId]]
- QR code image:
[[nodes.7.data.qrCode]]
- Issue date:
[[nodes.7.data.issuedDate]]
-
Output: Image URL or base64-encoded image
-
Image format: PNG (recommended for email compatibility)
9. Send Certificate Email (gmail.sendEmail)
-
To:
[[nodes.1.data.email]]
-
Subject:
Your CEU Certificate - [[nodes.1.data.courseTitle]]
-
Body: Professional HTML email with:
- Greeting with participant name
- Certificate image attachment
- Certificate ID for reference
- Instructions for verification via QR code
- Footer with course details
-
Attachment: Certificate image from node 8
-
Test mode: Send to yourself first
10. Notify Organizers (Slack) (slack.sendMessage)
11. Log to Google Sheets (googlesheets.appendRowFromUrl)
-
Sheet URL: Paste your Google Sheet URL here
-
Row data mapping:
- Column A (Timestamp):
[[nodes.7.data.issuedDate]]
- Column B (Participant Name):
[[nodes.1.data.participantName]]
- Column C (Email):
[[nodes.1.data.email]]
- Column D (Course Title):
[[nodes.1.data.courseTitle]]
- Column E (Certificate ID):
[[nodes.7.data.certificateId]]
- Column F (Status):
"Sent"
-
Ensure service account has Editor access to the sheet
12. Success Response (core.respondToWebhook)
-
Purpose: Confirms successful certificate generation
-
Body:
{"success": true, "message": "CEU Certificate generated and sent successfully", "certificateId": "[[nodes.7.data.certificateId]]"}
-
HTTP Status: 200 (OK)
-
Return to caller: Certificate ID for reference
Testing Your Agent
Step 1: Prepare Test Data
Create a test webhook payload with valid sample data:
{
"participantName": "John Smith",
"email": "john.smith@example.com",
"courseTitle": "Advanced Project Management",
"courseDate": "2024-01-15",
"creditHours": 3
}
Step 2: Run Test Execution
- In TaskAGI, click Test Workflow
- Paste your test payload into the webhook body
- Click Execute
- Monitor the execution in real-time
Step 3: Verify Each Step
-
Nodes 2-3: Confirm required fields validation passes
-
Nodes 4-6: Check email validation succeeds with valid test email
-
Node 7: Verify certificate ID and QR code generation in output
-
Node 8: Confirm certificate image URL appears in node output
-
Node 9: Check your test email inbox for certificate email
-
Node 10: Verify Slack notification appears in your channel
-
Node 11: Check Google Sheet for new row entry
-
Node 12: Confirm success response in execution logs
Step 4: Expected Results and Success Indicators
✅ Success criteria:
- Email received with certificate attachment
- Slack notification posted to channel
- New row added to Google Sheets with all data
- Webhook returns HTTP 200 with success message
- Certificate ID is unique and consistent across all outputs
✅ Test with edge cases:
- Invalid email format (should fail at node 5)
- Missing required fields (should fail at node 2)
- Valid email that bounces (should fail at node 5)
