Email Magic Links

The JavaScript SDK provides a pre-built UI to trigger Email Magic Links, and methods to send and authenticate magic links that you can connect to your own UI. Use either of these approaches to quickly get up and running with magic links.

Methods

The SDK provides methods that can be used to send magic links and authenticate tokens in the links later.

To call these methods, Email Magic Links must be enabled in the SDK Configuration page of the Stytch dashboard.

Login or signup

The Login or signup method wraps the login or signup Email Magic Link API endpoint.

Method parameters

organization_id* string
email_address* string
login_redirect_url string
signup_redirect_url string
login_template_id string
signup_template_id string
locale string
import { useStytchB2BClient } from '@stytch/react/b2b';

export const Login = () => {
  const stytch = useStytchB2BClient();

  const sendEmailMagicLink = () => {
    stytch.magicLinks.email.loginOrSignup({
      email_address: 'sandbox@stytch.com',
      organization_id: 'organization-test-07971b06-ac8b-4cdb-9c15-63b17e653931',
    });
  };

  return <button onClick={sendEmailMagicLink}>Send email</button>;
};

RESPONSE

200
{
    "status_code": 200,
    "request_id": "request-id-test-b05c992f-ebdc-489d-a754-c7e70ba13141"
  }

Invite

The invite method wraps the invite Email Magic Link API endpoint. The organization_id will be automatically inferred from the logged-in Member's session.

Method parameters

email_address* string
invite_redirect_url string
invite_template_id string
name string
untrusted_metadata object
locale string
import { useStytchB2BClient } from '@stytch/react/b2b';

export const InviteMember = () => {
  const stytch = useStytchB2BClient();

  const inviteMember = () => {
    stytch.magicLinks.email.invite({
      email_address: 'sandbox@stytch.com',
    });
  };

  return <button onClick={inviteMember}>Invite a Member</button>;
};

RESPONSE

200
{
    "status_code": 200,
    "request_id": "request-id-test-b05c992f-ebdc-489d-a754-c7e70ba13141",
    "member_id": "member-test-32fc5024-9c09-4da3-bd2e-c9ce4da9375f",
    "member": {...},
    "organization": {...}
  }

Authenticate

The Authenticate method wraps the authenticate magic link API endpoint which validates the magic link token passed in.

If there is a current Member Session, the SDK will call the endpoint with the session token. This will add the new factor to the existing Member Session.

If there is an intermediate session token, the SDK will call the endpoint with it. If the resulting set of factors satisfies the organization's primary authentication requirements and MFA requirements, the intermediate session token will be consumed and converted to a Member Session. If not, the same intermediate session token will be returned.

If this method succeeds and the Member is not required to complete MFA, the Member will be logged in, granted an active session, and the session cookies will be minted and stored in the browser.

If this method succeeds and MFA is required, the intermediate session token will be stored in the browser as a cookie.

You can listen for successful login events anywhere in the codebase with the stytch.session.onChange() method or useStytchMemberSession hook if you are using React.

Method parameters

magic_links_token* string
session_duration_minutes* int
locale string
import React, { useEffect } from 'react';
import { useStytchB2BClient, useStytchMemberSession } from '@stytch/react/b2b';

export const Authenticate = () => {
  const stytch = useStytchB2BClient();
  const { session } = useStytchMemberSession();

  useEffect(() => {
    if (session) {
      window.location.href = 'https://example.com/profile';
    } else {
      const token = new URLSearchParams(window.location.search).get('token');
      stytch.magicLinks.authenticate({
        magic_links_token: token,
        session_duration_minutes: 60,
      });
    }
  }, [stytch, session]);

  return <div>Loading</div>;
};
