How can Yandex pull out the coordinates of a single point with the API?

Question

API

Good afternoon,
Tell me - how to turn such a thing: There is a container with a map, it is necessary that when you click on this map a label appears and the latitude and longitude coordinates are saved somewhere, it is desirable that this label can be moved and, accordingly, the coordinates should change, it is impossible to be able to put a second point. If, for example, you click on another place on the map, then either the old point disappears and a new one appears, or nothing should happen. Is it real to do?

Answer 1

This is more than realistic to do, moreover, some of this is already in the "sandbox" to the API. Try to do it yourself, and if a specific question arises in the process, please contact us.
