URL Manipulation

A request URL can be updated dynamically using replacement blocks and parameters on the method. A replacement block is an alphanumeric string surrounded by { and }. A corresponding parameter must be annotated with @Path using the same string.

@GET("/group/{id}/users")
List<User> groupList(@Path("id") int groupId);

Query parameters can also be added.

@GET("/group/{id}/users")
List<User> groupList(@Path("id") int groupId, @Query("sort") String sort)
