 * The ScheduledReports API lets you manage Scheduled Email reports, as well as generate, download or email any existing report.
 *
 * "generateReport" will generate the requested report (for a specific date range, website and in the requested language).
 * "sendReport" will send the report by email to the recipients specified for this report.
 *
 * You can also get the list of all existing reports via "getReports", create new reports via "addReport",
 * or manage existing reports with "updateReport" and "deleteReport".
 * See also the documentation about <a href='https://matomo.org/docs/email-reports/' rel='noreferrer' target='_blank'>Scheduled Email reports</a> in Matomo.
