# ISPConfig 3.1 API
# User must provide login data and URL to the ISPConfig installation incl. port. The remote user in ISPConfig must have access to:
# - DNS txt Functions
# Report bugs to https://github.com/sjau/acme.sh
# Values to export:
# export ISPC_User="remoteUser"
# export ISPC_Password="remotePassword"
# export ISPC_Api="https://ispc.domain.tld:8080/remote/json.php"
# export ISPC_Api_Insecure=1 # Set 1 for insecure and 0 for secure -> difference is whether ssl cert is checked for validity (0) or whether it is just accepted (1)
