The Google Slides API provides programmatic access to presentations that integrate data from various sources. This API allows developers to create slide decks automatically from user and system-provided data. Predesigned templates can be combined with a database containing customer details in order to create finished presentations. Request objects allow creating slides, apply transforms to elements, and change the order of slides.
With Google Slides, developers can build their own Google presentations from scratch or turn spreadsheets into slides with a few API calls. Wesley Chun at the G Suite Developer blog shows you how to format text in a variety of ways to create awesome presentations in Google Slides.
