# Remove a registration

`DELETE /signups/{id}/registrations/{rid}`

## Request

- Base URL: `https://thesignup.app/api/v1`
- URL: `https://thesignup.app/api/v1/signups/{id}/registrations/{rid}`
- Auth: HTTP bearer

Take one person off the signup: every Commitment they hold and every day they attend goes, and the registration is marked not attending. Destructive and immediate; notifies nobody. Repeating it returns the same end state. A Commitment on a past or cancelled date (a Locked Commitment) is history: moving it, or removing a registration that holds one, is refused with 400 and nothing is written. Returns the registration as it now stands.

## Path parameters

- `id` string, uuid, required
- `rid` string, uuid, required
