Tallyfy’s DELETE endpoint at
/organizations/[org_id]/guests/[guest_email] removes a guest by… Guests are external users who participate in specific tasks or processes. They don’t need a full member account. You can use the API to create, list, retrieve, update, and delete guests. Guest endpoints use the guest’s email address (URL-encoded) as the identifier in the path, not a numeric ID.
All endpoints are scoped to your organization at https://go.tallyfy.com/api/organizations/{org_id}/guests.
