• Edit the first lines of update.php

  • username -> The username for your FRITZ!Box to authenticate (so not everyone can update your DNS)

  • debug -> enables debug mode and generates output of update.php (normal operation has no output)
  • apiKey -> API key which is generated in netcup CCP
  • apiPassword -> API password which is generated in netcup CCP

• Create each host record in your netcup CCP before using the script. The script does not create non-existent records.

  • only the url needs to be adjusted, the rest is automatically filled by the FRITZ!Box
  • http or https is possible if valid SSL certificate (e.g. Let's Encrypt)
• Domainname: <host record that is supposed to be updated>
• Username: <username as defined in update.php>
• Password: <password as definied in update.php>
