I reverse-engineered the bookmarklet and the JS it calls - and can now do sharing from my chrome extension. Sharing works, but the API returns 502. Not a problem per se, just an observation.
UPD: Also, some content just seems to be dropped. Investigating 
Feel free to post urls (remember to remove the secret key) and I can let you know why it’s not working. Happy to help!
Thank you! For starters, I tried to share this via the standard bookmarklet:
It shares but the only text in the shared article is:
<mark>Copyright ©2025 Dow Jones & Company, Inc. All Rights Reserved. </mark><mark>87990cbe856818d5eddac44c7b1cdeb8</mark>
This url shares fine, but the API still returns 502 (no biggie, I just ignore this specific error code), still weird:
shameless plug :))))
sharing to NewsBlur works now!
this URL shares an empty body, both via the standard bookmarklet and via my plugin:
https://www.wsj.com/tech/meta-army-vr-headsets-anduril-palmer-luckey-142ab72a
It sure looks like there’s some blockage happening on the NewsBlur side. E.g., this link fails to be shared via bookmarklet.
Sorry, but there was an error trying to share this story.
When done via the API it posts my summary, but not the article body - link. I’m thinking - maybe there’s something inside HTML that NewsBlur doesn’t like? Maybe publish the list of allowed HTML tags that are acceptable?
