Authenticate
The Authenticate method wraps the authenticate Magic Link API endpoint which validates the magic link token passed in.
If this method succeeds, the user will be logged in, granted an active session, and the session cookies will be minted and stored in the browser.
You can listen for successful login events anywhere in the codebase with the stytch.session.onChange() method or useStytchSession hook if you are using React.
Additional configuration.
import React, { useEffect } from 'react';
import { useStytch, useStytchSession } from '@stytch/react';
export const Authenticate = () => {
const stytch = useStytch();
const { session } = useStytchSession();
useEffect(() => {
if (session) {
window.location.href = 'https://example.com/profile';
} else {
const token = new URLSearchParams(window.location.search).get('token');
if (token) {
stytch.magicLinks.authenticate(token, {
session_duration_minutes: 60,
});
}
}
}, [stytch, session]);
return <div>Loading</div>;
