API Integration for Traction Lift Control

I am seeking a solution to control a traction lift system via an API. The system should allow calling the lift to a specific floor and sending it to a specific floor. This control should be accessible through an app compatible with iOS, Android, and Web-based platforms.

Ideal Skills:
- Experience with lift control systems
- Proficiency in API development and integration
- Cross-platform app development skills (iOS, Android, Web)
- Knowledge of traction lift systems
