            | UNSUPPORTED      | The mentioned Api is not supported by the ASPSP, the Open Banking Service will throw an error if it’s used.     |
            | SUPPORTED        | The mentioned Api is supported by the ASPSP. This is mentioned for the following Api’s (because they are usually not supported): - POST /psus/{psuId}/Aspsps/{aspspId}/pre-authentication". If the Post is supported the corresponding api methods (GET, PUT, DELETE) are also supported, if defined in the swagger.|

            | SUPPORTED        | A subset of the values in the mentioned FieldName is supported. The Value field (which is always supplied with the SUPPORTED Type) will indicate which values are supported. If no value is provided by the Initiating Party the Open Banking Service will use a default value. If an unsupported value is used, the Open Banking Service will throw an error. |
            | MANDATORY        | The mentioned FieldName is mandatory and has to be filled. If supplied, the Value field will indicate which values are supported. If the Value field is not supplied no validation on the field is done by the Open Banking Service. If the mentioned FieldName is not filled by the Initiating Party the Open Banking Service will throw an error. If an unsupported value is used, the Open Banking Service will throw an error.     |
            | FORBIDDEN        | The mentioned FieldName is forbidden. The Open Banking Service will throw an error if the Initiating Party fills this field and the request will not be sent to the ASPSP.     |
