In APA Style, the DOI number should be included when available instead of the web address and the DOI should be clickable. If there is a only a string of numbers and letters given, turn this into a clickable link by putting https://doi.org/ at the beginning.
If you cannot find a DOI, leave it out.
Examples of a reference using a DOI can be found in the DOI section of Referencing components on the Introduction to referencing page.
