Google has slowly been introducing changes to the Google Search Console APITrack this API, all geared toward improving API performance in light of increased demand. The most recent changes will affect developers that are querying the API for internal data.
In regard to changes related to the Google Cloud Platform dashboard, the company noted that developers will see a drop in the old API usage report and an increase in the new report. Additionally, developers may need to update API Key restrictions, as recent changes may have affected Authentication standards. The announcement of these changes provides a how-to for developers that need to update key restrictions.
Google also announced modifications that will require developers that are “querying the API using a third-party API Library or querying the Webmasters Discovery Document directly,” to update these specs by the end of the year.
