# Resuming journeys using magic links in JavaScript

When the user clicks the magic link in their email, it launches your JavaScript login UI app in their browser.

|   | If the magic link doesn't open your JavaScript login app, ensure you have correctly configured your server's **External Login Page URL** property.Learn more in [Configuring servers for suspended authentication](index.html#server-config-magic-links). |

Contained within the magic link is the unique `suspendedID` parameter, which allows the server to resume the authentication journey, and restore any state it has captured so far.

Use the **Journey** client's `resume()` method, rather than `start()`, to continue the journey. You must pass in the URI that contains the `suspendedID` parameter:

Resuming a journey in a JavaScript login app

```js
const client = await journey({
  config: {
    serverConfig: {
      wellknown: 'https://signon.example.com/.well-known/openid-configuration',
    },
  },
});

const url = new URL(window.location.href);
const urlHasSuspendedId = url.searchParams.get("suspendedId");

if (urlHasSuspendedId) {
  // Resume existing journey, rather than starting a new one
  let step = await client.resume(url);
}
```
