Stytch - Auth platform for developers

The Send method wraps the send Email Magic Link API endpoint. This method requires that the user already exist within Stytch before a magic link may be sent. This method is useful for gating your login flow to only pre-created users, e.g. an invite or waitlist.

This method is also used when you need to add an email address to an existing Stytch User. If there is a currently valid Stytch session, and the user inputs an email address that does not match one on their Stytch User object, upon successful authentication the new email address will be appended to the emails array. Note, this does expose a potential account enumeration vector, see our article on preventing account enumeration for more details.
