If you share a link in WhatsApp, it gives a preview, which remains the same even after you update the link externally, for example a YouTube video link.

Is there a way to force WhatsApp to refresh this preview?

This question is regardless of the device you use (Desktop, Mobile, etc.).

I've found that adding random text to the end of the hyperlink clears the cache. so: https://yoursite.com/?876564 Also, make sure you have flushed your site cache before.

  • What do you mean flushed your site cache before? We're talking about sharing a link from a random site. – LWC Nov 25 '22 at 10:50
  • @LWC No we are not talking about sharing from random sites. We are talking about sharing your own links that you have updated and you want to update the preview snippet on WhatsApp as well. The proposed solution here is the correct answer, append a random query string to the URL to force WhatApp to scrape again. – GeorgeP Feb 07 '23 at 19:08
  • Cool, but since the question wasn't about self links, if one must flush then it solves a rather particular case of a general question. – LWC Feb 08 '23 at 20:50

Found in this answer:

Removing the http:// or https:// from the link will disable the Whatsapp rich-link previews:

  • Thanks, but my question was how to make sure the preview is up to date, not how to remove it altogether. – LWC Aug 19 '21 at 18:25
  • Please read the question again carefully. Your answer does **not** answer the original question. – DavidPostill Aug 19 '21 at 19:53

    That's the best answer I can give. There's no way to have a dynamic preview because of the way that Whatsapp works: The sender constructs the entire message (with the preview) and sends it as rich text. The text then goes into the recipient's chat as-is, as a local copy that is no longer related to the original and that can no longer be modified (only deleted). To have the preview re-generated, the message needs to be resent, because it's the sender that creates it. – harrymc Aug 19 '21 at 20:02
