According to APA 7th Edition guidelines you need to find out as much information as you can about who created and published a source and when. You communicate this to your audience through in-text and Reference List citations which your readers can look up themselves.
Recommended sources for help with APA style guidelines:
APA style requires that a Digital Object Identifier (DOI) be included in your citation, if available. To see if a journal article has been assigned a DOI, you can look it up on CrossRef or Ask a Librarian.
