APA Citation of Website With No Author Mentioned
DISCLOSURE: I work for Mendeley as a software engineer. The reason I have used Mendeley is to show how it would cite this particular reference with this particular citation style using a tool familiar with academics and scholars.



Based on my findings, the citation would look like:


  Apache Struts Team. (2018). Announcements 2018. Retrieved March 28, 2019, from https://struts.apache.org/announce-2018.html


And the in-text citation would look like:


  (Apache Struts Team, 2018)




Please find below the steps I took to produce this answer:


I imported https://struts.apache.org/announce-2018.html using a Mendeley tool; I manually entered missing information in an attempt to construct a reference similar to yours:


And this how the reference looks like in Mendeley:


I can select this reference a copy/paste it using a citation style:


The formatted citation will use this citation style:


This is what you get when you paste it:


  Apache Struts Team. (2018). Announcements 2018. Retrieved March 28, 2019, from https://struts.apache.org/announce-2018.html

Then I can use another Mendeley tool to produce an "in-text" citation: (using the same citation style as in step 3)


Which gives me this in-text citation:


  (Apache Struts Team, 2018)
