10. Metadata

To advertise its support for this feature, the supported list of authorization details types is included in the AS metadata response [RFC8414] using the metadata parameter authorization_details_types_supported, which is a JSON array.

Example:

{
  "authorization_details_types_supported": [
    "payment_initiation",
    "account_information"
  ]
}

Clients MAY indicate the authorization details types they will use when requesting authorization with the client registration metadata parameter authorization_details_types, which is a JSON array.

Example:

{
  "authorization_details_types": [
    "payment_initiation"
  ]
}

The registration of authorization details types with the AS is outside the scope of this specification.
