To whom it may concern,
You can find more information by following this link: https://www.apastyle.org/learn/courses/4210701
There are various platforms and organizations that offer instruction on APA or other formats and editing, but for your concern, you cannot really beat a course offered by the APA (American Psychological Association) itself. It appears relatively inexpensive and will give you CE (Continuing Education) college credits, which appear to contain or suggest certification as well.
Best of luck,
Ryan
