Description (last modified by talldanwp)

Originally reported in Gutenberg - Ticketed here, as it seems to be the oembed endpoint returning a 404 error.

### Description

On the latest version of WordPress on a self-hosted site the Block for SlideShare embed is not working. Any attempt to put in the URL of the slide as instructed fails. Message states "Sorry, this content could not be embedded." even though it is a valid url from SlideShare

Interestingly, previous slides that I have embedded are still visible. I can even duplicate those blocks. However I can't switch out the URL, the same "Sorry, this content could not be embedded." message happens if I attempt any replacement of the existing URL

I resorted to flipping to code view and embedding an iframe to get around the current blocker ( not ideal)

See this page for reference first deck is an iframe all others are successful embeds using the SlideShare block that were done over a year ago.

### Step-by-step reproduction instructions

  1. Select the Slide Share Block
  2. Attempt to enter a slide share URL such as
  3. The block will not accept the valid URL

### Screenshots, screen recording, code snippet

_No response_

### Environment info

WordPress 6.5.3 running 2017 theme.

### Please confirm that you have searched existing issues in the repo.


### Please confirm that you have tested with all plugins deactivated except Gutenberg.

It appears that the oEmbed API is not currently (or no longer) available.

Furthermore, the entire developer section of the website is no longer present either.

Compare to the last archived copy:

Relevant FAQ article suggests that paid accounts are going to be required to view content in the future:

I've submitted a support ticket, but to me, it appears like it might've been an intentional removal.
(Although the share feature still lists the [slideshare] shortcode, and the plugins that implement it appear like they'll still work, as it's just an iframe)

Slideshare was less than helpful, sounds like WordPress should just remove all related Slideshare oEmbed code, and leave it for various plugins to use their non-oembed embedder.

Hi dd32,
We apologize for the inconvenience.
SlideShare has deprecated the old embed codes due to security vulnerability issues.
The good news is that you can take steps to still view or embed the slideshow.
If you are:
An author of a private presentation whose embeds are no longer working:
• Reach out to the owner of the website embedding your presentation and ask them to re-embed the presentation using the new embed code.
The owner of a website that has code embedded in a SlideShare deck that has now been disabled:
• Reach out to the author of the presentation to get the new embed code
• Replace the old embed code with the latest embed code on your site
I hope this information was helpful to you. If you need any further assistance, please do not hesitate to let me know, and I will be happy to help!
Best regards,

I asked for clarification, and indeed:

You are correct, I'm afraid we're unable to offer oEmbed or API support.

  • Milestone changed from Awaiting Review to 6.6

Thanks Dion, I'll put this on the 6.6 milestone to remove them as a provider to avoid shipping now broken code.

This ticket was mentioned in PR #6751 on WordPress/wordpress-develop by @peterwilsoncc.

The Slideshare oembed endpoint has been effectively deprecated so should no longer be included in the allow list.
