Levels of API

1. can i use the " CMD_API_ACCOUNT_RESELLER " to create reseller using a reseller account.

if i can i have another two questions :
1.a : will it be registered on the reseller account ?
1.b : will it work by the reseller bandwidth/space ? (it will not be more than the space/bandwidth allowed to the reseller)

I don't think so. Currently the way DirectAdmin is setup does not allow reseller of reseller accounts. You could always create the script to use the admin login details to create the reseller however the new reseller would not count against the reseller that you had wanted to create the account.

thanks, i have another question
if i add to the skin in the left menu "Mini Reseller Level" where do I link it in order to make an index like "list packs", "list users".. in the usual reseller, and where do I edit the index.

thanks
