Authentication
Master Key
The Master Key is a unique security credential provided to you as part of the onboarding process. It serves as a critical component for managing access to the API, by allowing you to provision your own API Keys. As such, it can only authenticate against the /masterkeys and /apikeys resources. Attempting to pass the Master Key for authentication against other API resources will result in a 401 HTTP response.
API Keys
API Keys are your primary form of authentication against the API. They are unique keys that get passed in the x-api-key header and act as the credential to identify your account and authenticate your requests against the API.
