In-text reference (APA style) for website How do I make an in-text citation for an information acquired from a website (If the writer and publication date is known)? Is it necessary to write out the full URL? I found APAstyle.org's explanation ambiguous.
From Penn State University Libraries


  APA in-text citation style uses the author's last name and the year of
  publication, for example: (Field, 2005). For direct quotations,
  include the page number as well, for example: (Field, 2005, p. 14).
  For sources such as websites and e-books that have no page numbers,
  use a paragraph number.


So in your case you could cite (Author name, Year, Paragraph Number).

Here is some more information when you do not have page numbers from Prudue University OWL


  Sources Without Page Numbers
  
  When an electronic source lacks page numbers, you should try to
  include information that will help readers find the passage being
  cited. When an electronic document has numbered paragraphs, use the
  abbreviation "para." followed by the paragraph number (Hall, 2001,
  para. 5). If the paragraphs are not numbered and the document includes
  headings, provide the appropriate heading and specify the paragraph
  under that heading. Note that in some electronic sources, like Web
  pages, people can use the Find function in their browser to locate any
  passages you cite.
