Share the sample code using the interface call of iSports Api Sports Data www.isportsapi.com. This API endpoint returns instant corner event and technical statistics of football matches(GMT +00:00-23:59). The event will be added, modified or deleted. Each eventId stands for an event, which will only be added or deleted. You need to synchronize the data with eventId.
