The Metrics Report API is now generally available, allowing developers to build sophisticated reports into their web and mobile apps using aggregated metrics. The API returns tabular data containing metrics grouped by one or more dimensions, such as total sales and total orders for a specific time period and location. Developers can create custom metrics with filters and sort the results in various ways, including pagination. The API is currently only available via GraphQL, but it will be added to the Console experience soon. With the Metric Report API, developers can easily build reports that display data in a table format, making it easier to analyze and visualize their data.
