In the coming months, we will make changes to the [Display \& Video 360 API](https://developers.google.com/display-video/api/reference/rest.md.txt) and [Structured Data Files](https://developers.google.com/display-video/api/structured-data-file/format.md.txt) to improve API function and better align with the Display \& Video 360 product.  

<br />
