You need to apply for a transit visa if you are going to change from an international terminal to a domestic terminal of any Indian airport or if you are going to stay in an airport hotel even for a few hours. You don't need a transit visa if you stay in the waiting area reserved for international transit passengers in an Indian airport. Note that you can stay for a maximum period of 72 hours in India on a transit visa. You should have a confirmed air ticket for the onward journey.
