Gametron has a JSON REST API that covers 100% of the features of Gametron. This means you can automate and control everything from outside of the web user interface for example with a billing automation system. API keys are used to authorize your requests to the API (i.e. making sure they come from a legitimate source). Most integrations require an API key.
An API key is like a long password: store it in a safe place and don’t share it with anyone. An API key grants full access to the account under which it’s created.
