Included at example scripts utilizing the Mcity OCTANE API implementation for control of the Mcity test facility.
While not all functionality is included, this repository functions as a getting started guide for utilizing parts of the API. Please refer to the latest API documentation at https://mcity.um.city/apidocs for all supported features and functionality.
Core functionality of these examples is storing your user access token (usually in an environment variable), and making requests to the API through either a http request or a Socket.IO websocket. Any language which supports either type of functionality through supporting libraries can be used to access the API.
The scripts included default to the production environment as they are targeted at users presently renting the facility. The production server is https://mcity.um.city. To acquire a production access key you must rent the Mcity tes facility by scheduling through https://scheduling.um.city
Before your scheduled session, you can utilize these scripts against our test environment by making manual changes within the .html files and the env_sample (or .env) file to switch the server to https://mvillage.um.city
Mvillage is a test environment that mostly mirrors the production environment. At this time, the major difference between the two environments is that that many items will NOT have status tracked/updated and many users can be making requests (that will not be serviced) to the environment. The request notifications will be pushed via the Socket.IO instance, but will not be serviced like production would.
Mvillage for REST requests is effective for verifying message format is correct and seeing what sample responses could look like. Mvillage for Socket.IO is effective for verifying connection, authentication, subscription, request notifications, and all interaction on the USER channel. The socket.IO instance does not provide responses to request or live updates similar to the REST request Mvillage environment.
Documentation of the entire application and a test interface is available here: https://mcity.um.city/apidocs You can utilize the documentation interface to submit specific requests, or generate a cURL command to run from a terminal.
