Can You Help Me With Wix Router?

I haven't work with Wix Router yet. I was checking Wix Router APIs to understand what does do Wix Router and can I use it for my use case?

What I want to do: I wan to create a advanced digital product download system to keep files secure and create custom tokens to download products.

What I have planned generally:

1. After clicking download button on the 'my downloads' page. (Member Page)

2. A new tab will open and this will be the router page.

3. I will handle the request to check if this user can download this products (security checks...)

4. Then I will redirect user to download page which will be using limited time tokens.

I hope I was able to explain what I want to do. My questions about this is very simple if you guys have used Router or if you know what is it.

My Questions:

• Is Router right thing to do this or is there any better way to do it?

• I don't want to hurt my website SEO generally so how can I done it while using router. How can I tell Google to ignore these all router pages?

When I was checking APIs I saw ok() to send 200 response with some data. In here I created something like that is that correct way to let Google or other search engines ignore my router pages?

My Router Code To NOT Index Page:

export function product_download_Router(request, response) {
    let data = {
        "data1": "test"
    }

    let header = {
        "noIndex": true
    }

    return ok("productDownload-page", data, header)
}

API that I checked
