Hi, I am bit confused in how the external accounts and operators are
linked together. E.g. If I have an operator and he can access campaign
through browser, he is already having an access to campaign. So, do I
need to create an external account for him ?Also, in which cases, do I
need to really create an external account for an operator and what kind
of access is then granted to him because of external account. Is it
needed for API access ? If yes, is there a session token required to be
passed ...
