Trump has set himself up as the "Man to end wars and to broker ceasefires" and so it is essential that he visibly manages to achieve either one or the other.
My guess is that he has put pressure on Netanyahu to accept a ceasefire, however, I would be very surprised if Netanyahu had not extracted something from Trump in return.
Perhaps Israel asked for, or the US offered, to turn a blind eye to whatever Israel proposes to do in the West Bank in the future. It wouldn't surprise me.
