Issue branded certificate PDFs from Google Sheets with TemplateFox and Gmail

Description

This workflow turns a Google Sheet into an automated certificate-issuing pipeline. The moment a new completion row is added — whether by your training team, a Zap, or a quiz platform — a branded PDF/A-2b (archival-grade) certificate is rendered by TemplateFox, archived in Google Drive, emailed to the participant with a permanent link, and the original sheet row is updated with the Drive URL and issue timestamp. You get a complete audit trail without writing a single line of code.

Problem Solved

Issuing certificates manually means:

Copy-pasting names and dates into a Word or Canva file
Exporting to PDF, attaching to an email, and sending it one by one
Saving a copy somewhere your team can find later
Maintaining a separate tracker of who got their certificate
Inconsistent branding and typos that erode the document's authority

This workflow eliminates all of that. Drop a row in your sheet, get an archival-quality certificate delivered, archived, and tracked — every time, with the same branding.

Google account with Sheets, Gmail, and Drive enabled
Install the TemplateFox community node from Settings → Community Nodes

Setting Up Your Template

You need a TemplateFox certificate template for this workflow. You can:

Start from an example — Browse certificate templates, pick one you like, and customize it in the visual editor with your colours, logo, and signatures
Create from scratch — Design your own certificate in the TemplateFox editor

Once your template is ready, select it from the dropdown in the TemplateFox node — your fields load automatically. Drag each field directly from the Google Sheets trigger output panel onto the matching template field. No code needed.

The workflow renders the certificate as PDF/A-2b, a modern archival standard that guarantees the file looks identical decades from now — perfect for official credentials. You can switch to PDF/A-3b in the TemplateFox node options if your training body requires it.

Workflow Details

Step 1: Google Sheets Trigger — New Completion Row
Watches a Google Sheet for new rows. Expected columns: Participant Name, Email, Course, Completion Date, Instructor. The trigger polls every minute by default.

Step 2: TemplateFox — Generate Certificate (PDF/A-2b)
Maps the row data directly to your certificate template fields and renders an archival-grade PDF. Static fields like your logo, signatures, and organisation name should be set inside the template editor itself — no need to pass them through n8n.

Step 3: Download PDF
An HTTP Request node downloads the rendered PDF as a binary file, ready to be uploaded to Drive.

Step 4: Archive to Google Drive
Uploads the PDF to your chosen Google Drive folder, named certificate-<email>.pdf for easy auditing. The node returns a permanent webViewLink that's used downstream.

Step 5: Email Certificate
A Gmail node sends a styled HTML email to the participant with a "Download your certificate" button pointing to the permanent Drive URL. Course name and completion date are included from the trigger row.

Step 6: Update Sheet Row
The original row in your Google Sheet is updated with two new values: Certificate URL (the permanent Drive webViewLink) and Issued At. Matching is done by Email, so even if rows are reordered the right one is updated.

The whole pipeline runs in a single horizontal chain — clean to read, easy to debug.

Customization Guidance

Static template content:** Set your organisation's logo, signatures, and any constant fields directly in the TemplateFox template editor — they never change between certificates.
PDF/A variant:** Switch to pdf/a-3b in the TemplateFox node options if you need PDF/A-3 (archival + attachments).
Pass/fail gate:** Add an IF node after the trigger to skip rows where Score is below your passing threshold.
Batch issuing:* Replace the Sheets trigger with a *Schedule Trigger** + a Get Many Rows step to issue certificates nightly instead of one-by-one.
Drive organisation:** Use a sub-folder per course by templating the file name with {{ $('New Completion Row').first().json.Course }}/....
Slack alert:** Add a Slack node after the Drive step to notify your training team in #training-ops.

Note: This template uses the TemplateFox community node. Install it from Settings → Community Nodes.
