MultiSig accounts list

[mohamedevv]

I'm building an app and I need to get a list of accounts under my address control but I can't find anything about that so I get the link from the request at https://tronscan.org/#/wallet but I still can't send it back because the need to signature and nonce ,
i have try to get the list with out this parameter and the response is {"code":20004,"message":"Error param.","data":null},
can i get any way to git it or know where is signature and nonce come from?
