Return type: Server_DH_Params

Can bots use this method: YES

MadelineProto Example:

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$Server_DH_Params = $MadelineProto->req_DH_params(['nonce' => int128, 'server_nonce' => int128, 'p' => 'string', 'q' => 'string', 'public_key_fingerprint' => long, 'encrypted_data' => 'string', ]);

PWRTelegram HTTP API example (NOT FOR MadelineProto):

As a bot:

POST/GET to https://api.pwrtelegram.xyz/botTOKEN/madeline

Parameters:

• method - req_DH_params
• params - {"nonce": int128, "server_nonce": int128, "p": "string", "q": "string", "public_key_fingerprint": long, "encrypted_data": "string", }

As a user:

POST/GET to https://api.pwrtelegram.xyz/userTOKEN/req_DH_params

Parameters:

nonce - Json encoded int128

server_nonce - Json encoded int128

p - Json encoded string

q - Json encoded string

public_key_fingerprint - Json encoded long

encrypted_data - Json encoded string

Or, if you're into Lua:

Server_DH_Params = req_DH_params({nonce=int128, server_nonce=int128, p='string', q='string', public_key_fingerprint=long, encrypted_data='string', })
