Class: ConfigurationPlatform: ApppiumLanguage: C# SDK:
This property can be used to set and retrieve your Eyes license key.
To obtain your API key, see How to obtain your API key.
string configval; // give relevant initial value config.ApiKey = configval; configval = config.ApiKey
Set this immediately after the Eyes object is created (before calling Open). If you have an environment variable called APPLITOOLS_API_KEY that is set to the value of your API key, then you do not need to call this method, and Eyes will take the string from the environment value.
