APA 6th Edition (scroll down for APA 7th edition)

A DOI is "is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet" (American Psychological Association, 2010, p. 189). The DOI may "be hidden under a button labeled Article, Crossref, PubMed, or another full-text vendor name" (p. 189) when you retrieve the article from one of RRU's electronic databases. Click on the button to see the DOI. If a DOI is available for an article, no other retrieval information is required; however, if the article hasn't been assigned a DOI but was retrieved from a password-protected database, provide the home page URL of the database or the name of the database instead of a DOI. See "How do I reference a journal article that has a DOI in APA Style?" and "How do I reference a journal article in APA Style (no DOI)?" for more information.

Here's the format for a journal article reference that uses a DOI:

Author, A.A., Author, B. B., & Author, C. C. (year). Title of article. Title of Periodical, xx(x), pp-pp. doi: xxxxxxxxx OR http://dx.doi.org/xxxxxxxxx OR https://doi.org/xxxxxxxxx

Please see "A DOI Primer" and "DOI Display Guidelines Update (March 2017)" from the APA Style Blog for more information on DOIs.

A DOI “is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet” (American Psychological Association, 2020, p.298). DOIs are presented as hyperlinks in APA Style in the basic format of https://doi.org/xxx; following the International DOI Foundation’s recommended format for DOIs in a reference list.

 If a DOI is available for an article, no other electronic retrieval information is required. If a nondatabase URL is available for articles without a DOI, use this link instead of a DOI; however, if the article hasn’t been assigned a DOI but was retrieved from a password-protected academic research database, do not use the URL instead of the DOI.
