Before we get into the nitty gritty pretty amazing details about this new amazing about the Search Analytics API, read everything about the API here.
Now, you can access Google Discover & Google News data using the API which was a highly requested feature by Technical SEO Experts around the globe.
The searchType parameter, which previously enabled you to filter API calls by news, video, image, and web, will be renamed to type and will support two additional parameters: discover (for Google Discover) and googleNews (for Google News). Please note that while we renamed the parameter to type, they’re still supporting the old name searchType.
In the Search Console Performance reports, some metrics and dimensions are compatible only with some data types; for example, queries and positions are not supported by the Google Discover report. In the same way, if an unsupported dimension is requested, the API will return an error message. That’s why they’ve also added the regex support. Two new operators will be added to the existing match operations: includingRegex and excludingRegex.
