      authentication types:
        * SMS_OTP - An SCA method, where an OTP linked to the transaction to be authorised is sent to the PSU through a SMS channel.

        * CHIP_OTP - An SCA method, where an OTP is generated by a chip card, e.g. an TOP derived from an EMV cryptogram. To contact the card, the PSU normally needs a (handheld) device. With this device, the PSU either reads the challenging data through a visual interface like flickering or the PSU types in the challenge through the device key pad. The device then derives an OTP from the challenge data and displays the OTP to the PSU.

        * PHOTO_OTP - An SCA method, where the challenge is a QR code or similar encoded visual data which can be read in by a consumer device or specific mobile app. The device resp. the specific app than derives an OTP from the visual challenge data and displays the OTP to the PSU.

        * PUSH_OTP - An OTP is pushed to a dedicated authentication APP and displayed to the PSU.

          Type of links admitted in this response, (further links might be added for ASPSP defined extensions):
          - “redirect”: In case of an SCA Redirect Approach, the ASPSP is transmitting the link to which to redirect the PSU browser.
          “oAuth”: In case of a SCA OAuth2 Approach, the ASPSP is transmitting the URI where the configuration of the Authorisation Server can be retrieved. The configuration follows the OAuth 2.0 Authorisation Server Metadata specification.
          “updatePsuIdentification”: The link to the payment initiation resource, which needs to be updated by the PSU identification. This might be used in an embedded, redirect or decoupled SCA Approach, where the PSU ID was missing in the first request.
          “updatePsuAuthentication”: The link to the payment initiation resource, which needs to be updated by a PSU password and eventually the PSU identification if not delivered yet. This is used in case of the Embedded or Decoupled SCA approach.
          “selectAuthenticationMethod” : This is a link to a resource, where the TPP can select the applicable strong customer authentication methods for the PSU, if there were several available authentication methods. This link contained under exactly the same conditions as the data element “authenticationMethods”, see above.
          “authoriseTransaction” : The link to the payment initiation resource, where the “Payment Authorisation Request” is sent to. This is the link to the resource which will authorise the payment by checking the SCA authentication data within the Embedded SCA approach.
