Even though APA 6th edition has 77 different reference formats from blogs to newspapers to videos to academic journals, there are really only two ways to put in a citation. I always tell students to cite as you write and all you need to put in your citation is AY or AYP -- author's last name and year of publication if you are paraphrasing or summarizing in your own words and author's last name, year of publication, and page or paragraph number where the reader can find the direct quote you used.

For instance for paraphrases and summaries:
(Smith, 2003).
(Smith & Jones, 2003)
(Smith, Jones, & Brown, 2003).

Note in citations we use the ampersand (&) and not the word "and".

For a quote, the citation would look like this:
(Smith, 2003, p. 12)
(Smith & Jones, 2003, para. 12)
(Smith, Jones & Brown, 2003, p. 12)
