Create a credential offer

Edit online

The relying party issuer application provides the user experience that guides the user to initiate a request for credential issuance. The relying party application creates a credential offer and initial issuance state with the issuing agent that is hosted at the DC Agency Service. The relying party application is responsible for sourcing and supplying the attributes and values that are minted into the credential.

Note: Use an access token that is obtained by using the client credentials grant with the credentials of the issuing agent to initiate this call.

    "credential_configuration_ids": [
        "2:mso_mdoc:baf2fda8-c412-428d-afe5-022c809c2c2c"
    ],
    "credential_data": {
        "org.iso.18013.5.1:family_name": "Breton",
        "org.iso.18013.5.1:given_name": "Jessica",
        "org.iso.18013.5.1:driving_privileges": "CAR",
        "org.iso.18013.5.1:document_number": "1012923848"
    }
}

The successful result of this call is a response that contains an OID4VCI credential offer. The relying party issuer application displays a QR code or notifies the user wallet about the offer.
