You are helping me build the following AI agent workflow.

## Goal
Verified User Profile Automation: Validates new user emails via API, generates a branded PDF profile, sends it by email, and logs the result in Google Sheets.

## Specification
- What it does: You instantly receive a branded PDF profile by email once your signup is verified, with every new registration automatically logged to Google Sheets for easy tracking. This process validates your address via the VerifiEmail API and converts your HTML template into a professional document without manual steps.
- Trigger: Triggered by an event (Event · on webhook POST)
- Autonomy: Fully hands-off
- Expected setup effort: under an hour
- Tools/services involved:
  - HTTP Request: Receive user signup data via webhook
  - VerifiEmail API: Validate email addresses
  - HTMLcsstoPDF: Generate PDF profiles from HTML
  - Gmail: Send welcome emails with attachments
  - Google Sheets: Log verified user data

## Known pitfalls, handle each one explicitly in your implementation
1. HTMLcsstoPDF may truncate long tables if page breaks are not explicitly defined in the CSS, so add @page rules to control layout.
2. Gmail API quotas reset daily and can be exhausted quickly during testing, so monitor usage limits and throttle batch operations accordingly.
3. Sensitive user data in Google Sheets might expose personal information if permissions are too broad, so restrict sheet access to authorized service accounts only.

## Reference implementation
https://n8n.io/workflows/10163 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
