To interact with secured endpoints of the Domino API, you must send an API authentication key along with your request. These keys identify you as a specific Domino user, and allow Domino to check for authorization.
To find your API key, first open your Account Settings.
In the setting menu, click API Key. You will see a panel that displays your key. Refer to the API documentation for information about how to use this key.
Be advised that any person bearing this key can authenticate to the Domino application as the user it represents and take any actions that user is authorized to perform. Treat it like a sensitive password.
