Matomo API
This API is the Metadata API: it gives information about all other available APIs methods, as well as providing human readable and more complete outputs than normal API methods. Some of the information that is returned by the Metadata API: the dynamically generated list of all API methods via "getReportMetadata" the list of metrics that will be returned by each method, along with their human readable name, via "getDefaultMetrics" and "getDefaultProcessedMetrics" the list of segments metadata supported by all functions that have a 'segment' parameter the (truly magic) method "getProcessedReport" will return a human readable version of any other report, and include the processed metrics such as conversion rate, time on site, etc. which are not directly available in other methods. the method "getSuggestedValuesForSegment" returns top suggested values for a particular segment. It uses the Live.getLastVisitsDetails API to fetch the most recently used values, and will return the most often used values first. The Metadata API is for example used by the Matomo Mobile App to automatically display all Matomo reports, with translated report & columns names and nicely formatted values.
