I'm sorry, but the knowledge sources do not contain explicit information on how to configure Ory to send an access token with a

c_nonce

. The available documentation describes how to use and introspect access tokens, configure JWTs, and handle verifiable credentials (where a

c_nonce

may be returned in error responses when requesting a verifiable credential), but it does not detail a method for including a

c_nonce

directly in the access token issued by Ory or its OAuth2/OIDC flows. If you are referring to the

c_nonce

used in the context of verifiable credentials (for proof-of-possession flows), the API may return a

c_nonce

in a 400 Bad Request response when a credential is requested, indicating that the client should use this nonce in the proof JWT for the next request. However, this is part of the verifiable credential issuance process, not the standard access token issuance process [Ory API Reference – createVerifiableCredential](https://raw.githubusercontent.com/ory/docs/master/docs/reference/api.json). If you need more specific behavior, such as including a

c_nonce

in access tokens, you may need to consult Ory's support channels or feature request forums, as this is not covered in the current documentation.
