Named Credentials create APIs missing Label and Name values?

Question

I'm looking at these three pieces of documentation:

• The ConnectApi.NamedCredentials class and specifically the createCredentials method
• The ConnectApi.CredentialInput class that defines the argument for the createCredentials method
• The Named Credential REST API that supports a POST so presumably can create a Named Credential and is probably what is wrapped by the above Apex classes

and do not see in any of them the ability to set a Label or Name (that can be set through the Setup UI).

What am I missing here?

PS

Trying an instanceof reports:

Operation instanceof is always false since an instance of ConnectApi.CredentialInput is never an instance of ConnectApi.NamedCredential

and calling createCredentials with a valid externalCredential resulted in this message saying a UserExternalCredential is being created which is not what I'm looking for (well I guess the method name and documentation are vague here):

ConnectApi.ConnectApiException: The UserExternalCredential object couldn't be saved because it's associated with an external credential with the following authentication protocol: Oauth

Answer 1

My conclusion here is that the ConnectApi.NamedCredentials class is not designed to create NamedCredential or ExternalCredential records but is designed to allow ExternalCredential records to be read and probably UserExternalCredential records to be created.
