title: Firebase Dynamic Link Preview Content
body: <p>I have a dynamic link which is linked / setup through my <code>Firebase</code> console.</p>
  <p><a href="https://i.stack.imgur.com/IhTWL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IhTWL.png" alt="enter image description here" /></a></p>
  <p>This link works as expected through a Facebook link share generated from the following:</p>
  <pre><code>NSURL *link = [[NSURL alloc] initWithString:@&quot;https://myapp.page.link/page?parameter=123&quot;];
  
  NSString *dynamicLinksDomain = @&quot;myapp.page.link&quot;;
  FIRDynamicLinkComponents *linkBuilder = [[FIRDynamicLinkComponents alloc]
                                           initWithLink:link
                                           domain:dynamicLinksDomain];
  linkBuilder.iOSParameters = [[FIRDynamicLinkIOSParameters alloc]
                               initWithBundleID:@&quot;com.example.MyApp&quot;];
  
  content.contentURL = linkBuilder.url;
  
  [FBSDKShareDialog showFromViewController:controller withContent:content delegate:self];
  </code></pre>

  <h2>The problem:</h2>
  <ul>
  <li>❌ When the user taps the link <strong>WITH</strong> the passed <code>parameter=123</code>, it delivers them to the &quot;correct&quot; but very much empty page (shown below on the <strong>LEFT</strong>.)</li>
  <li>✅ When the user taps the link <strong>WITHOUT</strong> the passed <code>parameter=123</code>, it delivers them to the intended page (shown below on the <strong>RIGHT</strong>).</li>
  </ul>

  <p>As I said above, the links work fine. Meaning, when tapping &quot;OPEN&quot; it takes the user to either the app (if installed) or the App Store. Even <strong>with</strong> the parameter passed, I <em>do</em> receive it correctly in the app through the URL, but my question is:</p>
  <blockquote>
  <p>How can I pass parameters through my dynamic link while maintaining the preview page <strong>with</strong> my applications content?</p>
  </blockquote>

  <p>Any help is much appreciated - thanks in advance!</p>
  <h2>NOTE:</h2>
  <p>I have tried adding components to my dynamic link deep link through the Firebase console, such as <code>...page.link/parameterID</code> to see if it anticipates looking for a value there. No luck. I'm sure it's something to do with the setup but I've been unable thus far to <strong>keep the content with the passed parameter.</strong></p>
