Hello there.
I noticed that there has been a change in the past few days according to how the facebook scraper gets redirected when hitting a dynamic link.
Now, it gets redirected to
XXXXX.app.goo.gl/s with parameters socialImageLink, socialTitle, socialDescription and a new entry: socialUrl.
Before, I was able to use the metadata of the original link to get a nice preview on the facebook timeline.
Now, if I do not provide any social metadata using the parameters "st", "sd" and "si", when constructing the URL manually, the preview (scraped by facebook) is broken.
To solve this, I would suggest that if no social parameters are passed, the original meta data from the link is used (as was happening last week).
In any case, it would be very useful to know how the parameter socialUrl can be set, as for now it is not documented yet (I tried passing "su" in the manual URL construction but I guessed wrong, doesn't work).
Cheers,
Rocco Ghielmini
