Each member of the AcceptedCredentials array is an inner object named Credential with the following nested fields:

Field	JSON Type	[Internal Type][]	Required?	Description
Issuer	String - [Address][]	AccountID	Yes	The issuer of the credential.
CredentialType	String	Blob	Yes	The type of credential, as hexadecimal. This is an arbitrary value from 1 to 64 bytes that the issuer sets when they issue a credential.

{% admonition type="info" name="Note" %} In the usual JSON format, inner objects are wrapped in an object with one field, whose name defines the inner object type. In this case, the wrapping field is named Credential. For example:

"AcceptedCredentials": [
    {
        "Credential": {
            "Issuer": "ra5nK24KXen9AHvsdFTKHSANinZseWnPcX",
            "CredentialType": "6D795F63726564656E7469616C"
        }
    },
    // ... additional Credential inner objects ...
]
