You are helping me build the following AI agent workflow.

## Goal
Create New User In Notion From Form: New form submission? The agent checks if the user exists in Notion and creates a new entry with their name, email, and current semester.

## Specification
- What it does: Capture new sign-ups instantly by automatically creating Notion entries for users who don't exist yet. The agent pulls name, email, and current semester from your form submission to keep your database up to date without manual work.
- Trigger: Triggered by an event (Event · on form submission)
- Autonomy: Fully hands-off
- Expected setup effort: under an hour
- Tools/services involved:
  - Notion: User database management

## Known pitfalls, handle each one explicitly in your implementation
1. Notion API requires specific property IDs rather than names, so you must map these correctly before sending requests.
2. The semester relation expects a page ID object, not just the text name, so ensure you fetch the correct ID first.
3. Webhook handlers often fail silently on malformed JSON, add explicit error logging for debugging purposes.

## Reference implementation
https://n8n.io/workflows/1373 (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.
