An API key is a unique identifier that verifies that you are a user in DigiCert ONE when you request to perform an action via the DigiCert ONE API. It allows applications to securely communicate with the API and DigiCert ONE client tools.
When you create an API key, it will have the same permissions and scope as your user profile in DigiCert ONE. Actions performed using your API key are logged under your username in the Account Manager audit logs.
To authenticate with the DigiCert ONE API, include your API key in the request header. If you prefer not to use an API key, you can use a client authentication certificate instead.
Note
If your API key expires, is deleted, or is disabled, any API integrations using it will stop working.
