Builder content link

Builder public api key

What are you trying to accomplish
I would like to launch pages to our production environment, but have them only be accessible if a queryParam of preview=true is included in the URL.

I set up a “queryParam” Custom Targeting Attribute as suggested in this post:

I then attempt to add targeting to the queryParam in the page targeting (see screenshot)

However, when I then try to hit the URL with the query param, I don’t successfully target the page and I get our standard 404 page.

Hey @alexleeRS great question

So the article you link has a number of things that make it Shopify-specific, such as the need to include a <script> with window.builderWcLoadCallbacks, and the toggle to render the section model client-side only.

Since I don’t believe your page is using Shopify, you won’t actually need to do any of that. In order for targeting to work for non-Shopify customers, you need to pass the targeting values to Builder within your code base. You probably could find a way to access the query param and pass it to and your builder.get() call, but that might be difficult since I believe you are also using SSR.

Because of all of that, I actually think a much more straight forward approach is to conditionally render the based on if the query param is present/true. So for example, if I had an app matching this starter: Next JS Simple Starter

You could change the Page element to something like:

export default function Page({ page }) {
  const router = useRouter()
  if (router.isFallback) {
    return <h1>Loading...</h1>
  const isLive = !Builder.isEditing && !Builder.isPreviewing

  if ((!page && isLive) || (isLive && !router.query.preview)) {
    return (
          <meta name="robots" content="noindex" />
          <meta name="title"></meta>
        <DefaultErrorPage statusCode={404} />

  return (
        <meta name="viewport" content="width=device-width, initial-scale=1" />
      <BuilderComponent model="page" content={page}>
        This is default component

Or essentially some version of:

if (router.query.preview || Builder.isEditing || Builder.isPreviewing) {
  /// render builder content

Do you think that will achieve the end result you are looking for of conditionally displaying pages based on the ?preview=true param? Test it out and let me know if it works for you!
