Working with Backbone Events to trigger post with different methods appended to Collections URL

Question

I am working with a handful of RESTFul API's that are as follows in concept.

domain.com/api/?id=xxxxx as the getter API call for the model/collection

In this case for me though there is several POST based setters that look like.

domain.com/api/start?id=xxxxx
domain.com/api/stop?id=xxxxx
domain.com/api/method?id=xxxxx
domain.com/api/thing1?id=xxxxx
domain.com/api/thing2?id=xxxxx

So I am trying to figure out how to trigger a POST based on the collection/model URL but appending start, stop, method, thing1, thing2 to it.. along with the id= as depicted.
