have you tried making a blank post and checking headers/cookies/response source?

[abdoelallam]

@spicy Yes but I didn't find it

[matricx]

it must be from somewhere

[spicy]

@abdoelallam have you tried reversing and trying to find a hash from that.

they must be hashing a response or something. try analyzing and identifying the hash, and hash the PostData or anything you can think of.
