In our APA Citation guide, we have a section on DOI and how to look up the DOIs of articles.
The lookup tool is https://www.crossref.org/guestquery/.
There's not always a DOI for every digital article, If there is no DOI, you use the URL of the journal homepage in the "location" field of the citation.
In an APA references entry, that would look like this: Retrieved from http://xxx.website.zzz
In an MLA works cited entry, that would look like this: ....year, xxx.website.zzz.
