Questions about packets/client

[mrk]

How do you know which packet/format the client expects in a given request?

For example, I'm trying to complete RequestNewHennaCompose in BattleChronicle. I have already enabled the packet debug suggested at: https://l2jmobius.org/forum/index.php?topic=7416

What method/tool do you suggest to know which packet (format) to send to the client, or which packet the client expects?

        OutgoingPackets.EX_PAYBACK_LIST.writeId(packet);
        packet.writeD(3); // колличество строк // string size //nSize
        for (int i = 1; i < 4; i++)
        {
            //заполняем строку //fill the string
            //start _PaybackRewardSet
            packet.writeD(3); // колличество предметов в строке // item count in field (max 3)//i
            for (int j = 1; j < 4; j++)

            //start _PaybackRewardItem
            //заполняем предметы //fill the items
            {
                packet.writeD(57); // предмет // item id
                packet.writeD(1); // количество // count
            }

            //end _PaybackRewardItem

            packet.writeC(i); // cSetIndex
            packet.writeD(5); // сколько нужно потратить // how much you need //nRequirement

Thank you very much. Very didactic. Where/How do I get this first part of the code?

I managed to find the information. Thanks for putting me on the right path.
