Hi, I am wondering if it is possible to programatically create magic urls and send them out via SMS instead of requiring the user to input the number first?

That is possible. You can make the magic link in your API like this and send it via SMS:

```ts
async function createAndSendMagicLink() {
    let response = await Passwordless.createCode({ phoneNumber: "..." })
    let magicLink = `{websiteDomain}/{websiteBasePath}/verify?rid=passwordless&preAuthSessionId=${response.preAuthSessionId}#${response.linkCode}`;
    
    await Passwordless.sendSms({
        type: "PASSWORDLESS_LOGIN",
        phoneNumber: "...",
        urlWithLinkCode: magicLink,
        codeLifetime: response.codeLifetime,
        preAuthSessionId: response.preAuthSessionId
    })
}
```

You can also skip calling the `await Passwordless.sendSms` function and send the link yourself however you like.
