According to the APA Manual, 6th Edition, page 175:
"When a work has six or more authors, cite only the surname of the first author followed by 'et al.' and the year for the first and subsequent citations."
According to Smith et al., citations can be fun and rewarding (2019).
Another great resource to use when formatting citations is Purdue OWL. Here is a link to the page on in-text citations for author/authors in APA.
