# Swagger

Any authorized vchatCloud user can run the vchatCloud API without implementing the vchatCloud Swagger UI (opens new window) logic and see the results.
This document covers checking vchatCloud API specifications, applying authentication keys, and calling API with Swagger UI.

# View API

The vchatCloud API can be run by connecting to the vchatCloud Swagger UI (opens new window), and can be moved immediately to that API through the Swagger UI logo at the bottom right of the vchatCloud API list.
