The SenderID to be shown on the SMS recipients devices are important for the recipients to know who sent the message, whenever they are sent via APIs.

The K-premium service on Xoxzo enables the users to set the pre-registered SenderIDs as fixed SenderIDs, and to be shown on the recipients devices by specifying them with parameters.

Please be informed that one of the parameter on Xoxzo's K-premium service has been changed.

  • paramter (old): jp_kddi_sender

  • paramter (new): jp_kp_sender

As you find in our Documentation, please specify your pre-registered K-premium SenderID with this parameter together with one of the parameter below.

** Please note that the old paramter will not be available to use after 2020/10/01.
