I have only heard of the term "indirect object". In that sentence "John" is the indirect object.

Some modern grammars of English use "complement" about everything after the subject noun and the verb.
I don't know their terms and rules.

Older grammars of English say that a verb has a "direct object" and an "indirect object" and a "subject" -- up to three nouns for one verb.
