APA 7th edition requires in-text citations that include the author's last name and publication year in parenthesis. If the you are directly quoting a work, you should also include the page number. See examples below.
For the APA style bibliography, citations should be placed in alphabetical order by the last name of the first author. If you are citing an article without a specified author, use the Article Title. Capitalize only the first letter of the first word, proper names, and acronyms in the article title. Use only initials for authors' first and middle names. Write out all author names up to 20 authors.* For more than 20 authors, use ellipses.
1st author last name, first initial, 2nd author last name, first initial. (year). Article title. Journal title, volume (issue), page #s. DOI

Citation managers are very helpful for keeping your research organized and for citing sources in your papers. There are a few different ones out there, but I recommend Zotero, which is a free, open-source citation management software.
