# Continue signup, or validate a waitlist bypass code

`POST /api/v1/waitlist_applications`

## Request

- Base URL: `https://composal.com` (the document declares no server; this is the origin it was published from)
- URL: `https://composal.com/api/v1/waitlist_applications`
- Auth: none required

Unauthenticated. An invite_code alone validates a redeemable code and saves it in the browser session for subsequent password or OAuth signup. Validation does not redeem the code or create an account or waitlist row. Without a code, legacy name/email submissions continue to account creation; signup admission is enforced by the authentication endpoints.
