According to the APA Style website (2021), "A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works."

Example DOI: 10.4376/6630-4660.21.2.001

Not all articles will have a DOI, but if it does, you can find it listed in the Detailed Record page of a database (see screenshot below):

American Psychological Association. (2021). DOIs and URLs
