A DOI, or Digital Object Identifier, is a string of numbers, letters and symbols used to permanently identify an article or document and link to it on the web. A DOI will help your reader easily locate a document from your citation. Think of it like a Social Security number for the article you’re citing — it will always refer to that article, and only that one. While a web address (URL) might change, the DOI will never change.

Below are a few examples for citing with the APA 7^th Referencing Style. For more information, please view the file on the link.
