ResponseModes

OID4VP: In this mode, the Authorization Response is sent to the Verifier using an HTTPS POST request to an endpoint controlled by the Verifier. The Authorization Response parameters are encoded in the body using the application/x-www-form-urlencoded content type. The flow can end with an HTTPS POST request from the Wallet to the Verifier, or it can end with a redirect that follows the HTTPS POST request, if the Verifier responds with a redirect URI to the Wallet.

The Wallet adds the response parameter containing the JWT as defined in Section 4.1. of JARM and Section 6.3 in the body of an HTTPS POST request using the application/x-www-form-urlencoded content type.
