How to correctly implement the creation of an entity in accordance with the Rest API?

Question

RESTful API

I can’t find an unambiguous answer, you need to implement the creation of a rating for a specific event that differs in id, respectively, there are two options for urls:
Post helmet on
events/{event_id}/rate data {'name' : 'value', 'value': 5}
or
events/rate data {'name':'rate 1', 'value': 5, 'event_id': 23} In
general, the question is where should the event_id be in the url or as a transmitted data array and why please?
