Log in or create user

Log in or create User by email

POST
https://test.stytch.com/v1/magic_links/email/login_or_create

Send either a login or signup Magic Link to the User based on if the email is associated with a User already. A new or pending User will receive a signup Magic Link. An active User will receive a login Magic Link. For more information on how to control the status your Users are created in see the create_user_as_pending flag.

Next steps

The User is emailed a Magic Link which redirects them to the provided redirect URL. Collect the token from the URL query parameters and call Authenticate Magic Link to complete authentication.
