I'm using biblatex-apa and biber to write my research paper in APA format. I love using BibDesk and LaTeX compared to manually writing the bibliography in Pages, but I can't figure out the online bibliography types.

The Purdue OWL has a sample of an online periodical article,

Brownlie, D. (2007). Toward effective poster presentations: An annotated bibliography. European Journal of Marketing, 41, 1245-1283. doi:10.1108/03090560710821161

I can do this citation using the article type, but I would need a field for the DOI, how would I do this?

Also, for regular websites, I need the website title to appear in italics. Using biblatex-apa, the title of the webpage is not set in italics...?

Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Marco Daniel Oct 13 '13 at 16:57
The field for DOI is - you guessed it - doi. In your case that would be doi = {10.1108/03090560710821161},. To the title of @online entries in italics try \DeclareFieldFormat[online]{title}{\mkbibemph{#1}}. – moewe Oct 13 '13 at 17:31
Thanks, @moewe, the \DeclareFieldFormat trick is nifty. Do you know of any site that has a list of all the keys I can use? I'd like to not have to guess at tag names... ;) – architectpianist Oct 13 '13 at 18:31
By 'keys' do you mean 'entry fields'? If so, the complete list is given in the biblatex manual. On a TeX Live system, you can do texdoc biblatex; otherwise, check out [texdoc.net](texdoc.net) and search for 'biblatex'. – jon Oct 14 '13 at 6:03
You can find all the information you need, and much more, in the biblatex documentation (the texdoc.net version seems to be about an older release). § 2 would be of interest to you for all the entry types and their entry fields. – moewe Oct 14 '13 at 6:31

Thank you for the assistance! Here is the solution I used to format the online periodical article:

Author = {Caretta, Antonio and Mucignat-Caretta, Carla},
Date-Added = {2013-10-13 16:24:30 +0000},
Date-Modified = {2013-10-13 18:23:51 +0000},
Doi = {10.3390/cancers3010913},
Journal = {Cancers},
Number = {3},
Pages = {913-926},
Title = {Protein Kinase A in Cancer},
Url = {www.mdpi.com/2072-6694/3/1/913/pdf},
Urldate = {2013-10-13},
Year = {2011}}

To italicize the title, I used this code in the preamble for my document:

\documentclass[man, 12pt, biblatex-apa]{apa6}
\usepackage[english, british]{babel}
\usepackage[backend=biber, style=apa]{biblatex}
\setmainfont{Times New Roman}

I'm no expert in bibliographies, but I thought article would be better because it was in a journal originally. By providing the DOI I showed that it was an online document. – architectpianist Oct 14 '13 at 2:11
@Kurt "Cancers" seems to an (online) open access journal; it even has volume, issue (biblatex-speak number) and page numbers, so I think it's pretty @article-y. One could argue, though, that in this case the url is superfluous since a doi is already provided. – moewe Oct 14 '13 at 6:36
