The document outlines four major advantages of API testing over GUI testing: it is time-effective, language-independent, allows for easy GUI integration, and tests core functionality. API testing can significantly reduce testing time and offers improved test coverage and resource conservation. For more details, additional information can be found in a blog post linked in the document.
