# APA style in biblatex with three authors

I am trying to figure out why, when using biblatex with style = apa, there is no .et al abbreviation in my text with more than 3 authors. I cannot think of any plausible explanation, maybe someone sees smth that I don't in my latex preamble.

\documentclass[12pt]{article}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}

\usepackage[
backend = biber,
style = apa,
defernumbers=false,
uniquelist=true]{biblatex}
\DeclareLanguageMapping{english}{american-apa}

\usepackage{xpatch}

\AtEveryCitekey{\ifciteseen{}{\clearfield{namehash}}}

\xpatchbibmacro{cite}
{\printnames{labelname}}
{\ifciteseen
{\printnames{labelname}}
{\printnames[][1-99]{labelname}}}
{}
{}

\xpatchbibmacro{textcite}
{\printnames{labelname}}
{\ifciteseen
{\printnames{labelname}}
{\printnames[][1-99]{labelname}}}
{}
{}

\addbibresource{dummy_lit.bib} %name of the .bib file with my references

\begin{document}

I would like to have the abbreviation "et. al" in the running text whenever the references have more than three authors and not this:

\textcite{Author2000}

\end{document}


This is my bib entry stored in a separate file called: dummy_lit.bib

 @Article{Author2000,
author       =  {Last name1, Firstname 1 and Last name2, First name2 and Last name3, First name3 and Last name4, First name4 and Last name5, First name5},
title        =  {The title of my article},
journal      =  {The journal},
year         =  {2000},
volume       =  {1},
number       =  {2},
pages        =  {1-10},
keywords     =  {ref}
}

APA style requires that up to five authors are shown in full on a first citation, lists of three to five authors are only abbreviated to "et al." on subsequent citations. See for example http://blog.apastyle.org/apastyle/2011/11/the-proper-use-of-et-al-in-apa-style.html or 6.11 and 6.12 in the Publication Manual of the American Psychological Association.

And indeed if you cite an entry with five authors twice, you get.

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[backend = biber, style = apa]{biblatex}


So this is expected behaviour of the APA style as implemented by biblatex-apa.
If you want to change that behaviour, have a look at Setting maxcitenames for biblatex-apa and set \apamaxcitenames to 3 in the example.
Note that your two \xpatchbibmacro calls do nothing, because the patched code does not exist in the macros your are patching.
