What wallet app are you using?
For example if you are using Electrum, just paste the URI in the "
Pay to" field and all other fields will be filled automatically.
but I need a proof that this payment belongs to my user account !!
The website will generate a unique address for each user. However, I believe "327130" is your User ID on "
www.xxxxxxxxx.website".
Check it out and if it is indeed your uid then "31jT3vtzwkrRksSixxxxxbCrw15QZYwNZg" is your deposit address.
I suppose you edited the address befor posting it here for privacy reasons because it is an invalid address (do not send to it).
