A client authentication certificate is a digital certificate 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.
Instead of providing the API key to the DigiCert ONE API, you can generate a client authentication certificate and provide the file path of your installed authentication certificate in the request header.
Note
If the service user expires or is disabled, any API integrations using the client authentication certificate will stop working. To prevent disruptions, ensure the service user remains active or update affected integrations accordingly.
