Questions about making a Spotify account checker

[4]

Hi,

I've been trying to learn how to make account checkers for (relatively) simple sites for a few days now. I know how to make requests/get CSRF tokens/and other basic things so far, but I've been getting stuck when actually trying to send the data on the POST request.

With spotify specifically, the payload has one field called "recaptchaToken" which I am confused about. I originally thought I could get it the same way as a CSRF token but I was unable to. I tried hard-coding it as well but was still unable to get a good response from spotify.

If anyone can give me some headers that would be amazing.

Yeah, I got the same problem.
From what I understand, you still have to set cookies like "sp_key".

I don't think anyone's gonna help you, though. After all, these people want to sell their software...
I'll join the search though ;)
