As the world's largest elevator and escalator service provider, Otis is
                focused on keeping the world moving. Not only did we invent the safety
                
 elevator, we revolutionized its care. It was Charles Otis who gave his personal
                commitment to quality and customer service, handwriting
                our first maintenance contract and signing his name to it in 1861. Today, we're
                harnessing emerging technology and the internet of 
                things to deliver the personalized experience people know and want in today’s digital age.
            
Our name is Otis — and service is our signature
 
          
            
          
           
        
          
        
                    Every day, our teams roll up their sleeves to keep two billion people
                    on the move. They wear the Otis logo as a badge of honor and
                    see your building as their own. Now our teams are investing 
                    in the development of APIs to help integrate building data and apps like
                    eCall into your building applications. 
                
                    You need peace of mind and a hassle — free daily experience
                    with your elevators. So we provide you with instant access
                    to all of your account and service information via APIs.
                    Find out the real — time status of your elevators, what work is
                    completed and review performance trends over time.
                    
                
 
          
            
          
           
          
          
         
          
            
          
           
          
          
        
                    The future of service is a move towards predictive maintenance
                    to address issues before they occur. Our APIs allow you to
                    connect to the Otis Cloud to integrate elevator health status
                    information into your building management systems.
