# GDPR-Compliant Secure Prefill Tokens | NeetoCal

Prefill NeetoCal booking questions with a secure token so personal details never appear in the URL, browser history, or server logs.

## Overview

Secure prefill tokens in NeetoCal let you prefill booking questions without putting personal data in the URL. Standard prefilling adds details like name and email to the link, where they can end up in browser history and server logs. A prefill token keeps that data out.

Your website sends the customer's details to the NeetoCal API with an API key and receives a token. You redirect the customer to the booking page with that token, and NeetoCal fills in the questions automatically. Tokens work with any question's field code and stay valid for up to 30 days. Healthcare, legal, and finance teams use GDPR-compliant prefilling to protect customer privacy.
