Description

This workflow automatically generates personalized certificates in Google Slides and emails them to respondents only if they meet a minimum score threshold, using data submitted via Google Forms (stored in Google Sheets).

Ideal for:

• Online courses
• Quizzes and workshops
• Event participation certificates

Sheet Requirements

• Your connected Google Sheet (from the Google Form) must contain:
• Full Name – The name to appear on the certificate.
• Email – Recipient’s email address.
• Score – The test/quiz score used for threshold logic.

Setup Instructions

1. Connect Google Sheets – Make sure your Form responses are linked to a Sheet with the columns mentioned above.
2. Set Score Threshold – Modify the If node to your desired minimum score (e.g., >= 80).
3. Customize Certificate Template – Use a Google Slides file with text placeholders like {{Full Name}}.
4. Connect Gmail & Google Drive – For sending emails and saving generated certificates.
5. Update File IDs – Replace any placeholder Slide and Drive file IDs with your own.

Services Used

• Google Sheets (Form responses)
• Google Slides (Certificate template)
• Google Drive (Storage)
• Gmail (Email delivery)

Troubleshooting

• Issue: “Cannot read property ‘Score’” → Ensure your column names match exactly (Score, Full Name, etc.).
• Slides not replacing placeholders → Double-check placeholder format ({{Full Name}}) and capitalization.
• Emails not sending → Verify Gmail authentication and make sure the If node is correctly filtering results.
