AuthenticatorResponse.clientDataJSON - Web APIs
the clientdatajson property of the authenticatorresponse interface stores a json string in an arraybuffer, representing the client data that was passed to credentialscontainer.create() or credentialscontainer.get().
... syntax var arraybuffer = authenticatorattestationresponse.clientdatajson; var arraybuffer = authenticatorassertionresponse.clientdatajson; value an arraybuffer.
... properties after the clientdatajson object is converted from an arraybuffer to a javascript object, it will have the following properties: type a string which is either "webauthn.get" when an existing credential is retrieved or "webauthn.create" when a new credential is created.

Web Authentication API - Web APIs
browser calls authenticatormakecredential() on authenticator - internally, the browser will validate the parameters and fill in any defaults, which become the authenticatorresponse.clientdatajson.
...the parameters to the create() call are passed to the authenticator, along with a sha-256 hash of the clientdatajson (only a hash is sent because the link to the authenticator may be a low-bandwidth nfc or bluetooth link and the authenticator is just going to sign over the hash to ensure that it isn't tampered with).
... browser creates final data, application sends response to server - the create() promise resolves to an publickeycredential, which has a publickeycredential.rawid that is the globally unique credential id along with a response that is the authenticatorattestationresponse containing the authenticatorresponse.clientdatajson and authenticatorattestationresponse.attestationobject.

Attestation and Assertion - Web APIs
the attestation format contains two basic arraybuffers: clientdatajson - an arraybuffer that contains a json representation of what the browser saw when being asked to authenticate.
...the assertion format is fairly simple as it contains four basic arraybuffers: clientdatajson - the same as in attestation.
... authenticatordata - data created and/or used by the authenticator signature - a signature over the clientdatajson and authenticatordata that can be verified with the public key that was created during registration.
