The ObservePoint API has a robust set of endpoints for accessing and controlling virtually every feature in the platform. The documentation is stored at a different website, accessible at api.observepoint.com/swagger-ui/index.html. This website allows you to send API calls, receive responses, and copy the syntax in a number of different languages.
To interact with the API, you'll need your own API key, available in your ObservePoint profile settings. Be sure to keep your API key secure, as you would your own username and password.
