*Did the appointment took place?

No, not like this.

Did the appointment take place?
Yes, it took place as scheduled.

(Did took is simply ungrammatical.)

Another option is to use "meeting" instead of appointment.

Strictly speaking, there was an appointment to meet, so if the appointment does not get cancelled, the meeting will take place.

I dare say that from a purist point of view, that is certainly preferable, as the appointment itself does not take place, but whatever the appointment was for might or might not happen. An appointment is an agreement to meet.

So even better:

The meeting took place as planned.

Or if the appointment got cancelled:

That meeting never took place!
