Hi,

Using api customer to login and manage the their products, domains and invoices to make payments.

if client id and user id same When client logged with client email address which is working fine as expected.

if client id and user id not same When client logged with client email address which is not working as expected client information, products and invoices empty with api response.

Before GetClientsDomains  We need to validating the user login using ValidateLogin api ( https://developers.whmcs.com/api-reference/validatelogin/ ).

So ValidateLogin Response Parameters have only user id. but to get GetClientsDomains api ( https://developers.whmcs.com/api-reference/getclientsdetails/ ) we need clientid as Request Parameters

but userid and and clientid value is different
