You are helping me build the following AI agent workflow.

## Goal
Approval Workflow Handler: Automates approval requests by creating a pending record in Baserow, emailing the approver via SendGrid, and updating status upon decision.

## Specification
- What it does: You get instant notifications when your requests need approval via email, ensuring you never miss a decision. The system automatically tracks these approvals in Baserow and updates their status once an approver clicks the link to approve or reject them.
- Trigger: Run manually (Manual · on demand)
- Autonomy: Fully hands-off
- Expected setup effort: under an hour
- Tools/services involved:
  - n8n: Workflow orchestration platform
  - SendGrid: Sending approval and notification emails
  - Baserow: Storing and updating request records

## Known pitfalls, handle each one explicitly in your implementation
1. Sensitive data like employee IDs might leak in logs so mask personal information in all n8n execution history outputs.

## Reference implementation
https://n8n.io/workflows/12972 (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.
