Hi, I'm currently doing a class for twitter which works without their API, but I'm stuck with the ui metrics (a variable needed in the post request of a tweet). It looks like this:

ui_metrics:{"tt":74273,"v":2,"gts":0,"h":"7ad2bd27","b":"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"}

I did some research, but as this is pretty "new" they are no real open source answer. If anyone could lead me, or share their thoughts about this I would be glad!

Thanks anyone 🤝

Found a reversed version of the json that does the metrics: http://www.peopleperhour.com/job/javascr...net-849879

By the test I did, it looks like it's not needed, I can do the request without inserting anything, but on different websites people are saying that the ui metrics is a bot prevention, so by not adding it I might get my account closed (not sure tho).

Thanks for helping me btw 🤝

Find the javascript that is responsible for generating the UI metrics or w/e and study how it works. The Javscript might be obfuscated but deofs that and there you go. Other than that, judging from the data you posted, it seems like it's just a bunch of hashes.

[Ninja]

The JS is obfuscated, upon deobfuscating it you would find that:
"tt":74273,"v":2,"gts":0,"h":"7ad2bd27"
tt = time in milliseconds it took to fill out the form.
gts = guestid value from cookies.
v = 2.
h = generated with some algorithm which requires the parameters username, tt, gts.
b is generated using h and some more but I am leaving that to you as I dont want to spoil all the fun.

I have some code but I'm not at home atm. Idb has some code for the H parameter. Not sure if it still works but I think it would. It uses MSScriptControl to execute the JS but you can convert it to VB.net easily if you want (you dont need too though). I am on his shit list so I cant help you further with it lmao.

Thank you both for your precious help, I'll try to walk on my own now, updating this thread when I get stuck :D

Made it! Thanks to both of you, helped me a lot :)
I found that pretty funny, it was like achieving something :3

[thaledox]

Can you please share how did you manage to solve it? I am stuck in this ui_metrics thing for more than a week and I am going to lose my mind soon. Please help  😭
