Self-hosted dynamic DNS php script to update netcup DNS API from Router like AVM FRITZ!Box

Authors

Copy all files to your webspace
create a copy of .env.dist as .env and configure:
- username -> The username for your Router to authenticate (so not everyone can update your DNS)
- password -> password for your Router
- apiKey -> API key which is generated in netcup CCP
- apiPassword -> API password which is generated in netcup CCP
- customerId -> your netcup Customer ID
- debug -> true|false enables debug mode and generates output of update.php (normal operation has no output)
Create each host record in your netcup CCP (DNS settings) before using the script. The script does not create any missing records.

Go to "Internet" -> "Freigaben" -> "DynDNS"
Choose "Benutzerdefiniert"
Update-URL: https://<url of your webspace>/update.php?user=<username>&password=<pass>&ipv4=<ipaddr>&ipv6=<ip6addr>&domain=<domain>
- only the url needs to be adjusted, the rest is automatically filled by your AVM FRITZ!Box
- http or https is possible if valid SSL certificate (e.g. Let's Encrypt)
Single Domain:
- Domainname: <host record that is supposed to be updated>
Multiple Domains:
- Domainname: <first host record that is supposed to be updated>,<second host record that is supposed to be updated>,....
Username: <username as defined in .env file>
Password: <password as definied in .env file>

Go to "Control Panel" -> "External Access" -> "DDNS"
Click on "Customize Provider" to create a profile for your own DDNS server
Service Provider: This is the display name of your custom provider
Update-URL: https://<url of your webspace>/update.php?user=__USERNAME__&password=__PASSWORD__&ipv4=__MYIP__&domain=__HOSTNAME__
- Attention: The variables are delimited by two underscores
- Currently Synology custom DDNS does not support IPv6, for whatever reason.
Save your custom provider
Click on "Add" to create a DDNS job
Select your custom provider. Notice that an asterisk [*] has appeared in front of the name to signify that this is a custom provider.
Hostname: <host record that is supposed to be updated>
Username/Email: <username as defined in .env file>
Password/Key: <password as defined in .env file>
External Address (IPv4): probably "Auto", uses Synology service to find own external IP
External Address (IPv6): doesn't matter, currently not supported by Synology

Go to "Services" -> "Dynamic DNS"
Click on "Add" to create a DDNS profile
Service Type: "Custom"
Interface to monitor: <select you WAN interface>
Interface to send update from: <select your WAN interface>
Update URL: https://<url of your webspace>/update.php?user=<user from .env>&password=<password from .env>&ipv4=%IP%&domain=<host record to update>
Leave all other fields empty / default
