--- title: "Send" method: POST path: "/v1/magic_links/email/send" tags: ["Magic Links"] --- # Send `POST /v1/magic_links/email/send` ## Request - Base URL: `https://api.stytch.com` - URL: `https://api.stytch.com/v1/magic_links/email/send` - Auth: HTTP basic Send a magic link to an existing Stytch user using their email address. If you'd like to create a user and send them a magic link by email with one request, use our [log in or create endpoint](https://stytch.com/docs/api/log-in-or-create-user-by-email). ### Add an email to an existing user This endpoint also allows you to add a new email address to an existing Stytch User. Including a `user_id`, `session_token`, or `session_jwt` in your Send Magic Link by email request will add the new, unverified email address to the existing Stytch User. If the user successfully authenticates within 5 minutes, the new email address will be marked as verified and remain permanently on the existing Stytch User. Otherwise, it will be removed from the User object, and any subsequent login requests using that email address will create a new User. ### Next steps The user is emailed a magic link which redirects them to the provided [redirect URL](https://stytch.com/docs/guides/magic-links/email-magic-links/redirect-routing). Collect the `token` from the URL query parameters, and call [Authenticate magic link](https://stytch.com/docs/api/authenticate-magic-link) to complete authentication. ## Request body - ApiMagicV1MagicLinksEmailSendRequest: Request type - `email` string, required: The email address of the User to send the Magic Link to. - `login_template_id` string: Use a custom template for login emails.
