Formwerk Cookie Submission Target Domain Check

Use this endpoint when you need to specifically determine the submission target domain as observed through cookies on a web page, particularly for privacy audits, GDPR compliance checks, or security reviews. Prefer this over sibling endpoints (banner, iframe, script, network request) when cookie-based form submission tracking is the focus, and over the 'number of forms' or 'form method' cookie endpoints when the domain destination is the key concern.

• URL is unreachable or returns a non-200 HTTP status — endpoint returns an error or empty finding
• No cookies found on the target page — result may be empty or indicate absence of cookie-based submission data
• CSS selector matches zero elements — first matching element used or error returned
• Target domain is private or non-public IP — rejected per input validation
• URL exceeds 2048 character limit — input validation error
