When I was querying nearby Gym on snapfitness website, it targeted to an HTTP 404 page. As an automation test analyst, I wrote a letter to the webmaster with analysis pointing to backend RESTful API defect and hope it will help :_)
Note that this defect only happens with snapfitness.com, another domain snapfitness247.con.nzis still working fine to return correct JSON data on POST Web API call (thru postman).
