Every CallHub account is provided with a unique API that you can use to integrate CallHub with third-party applications.
To find your API key:
Click your Profile name and select Settings
Click on the API Key tab under the "General" section.
If you'd like to stop other applications (that you've integrated with) from accessing the data in your CallHub account, click Generate New Key. Resetting your API key would dissociate your CallHub account from all applications that you've integrated with using your previous API key.
