# acme.sh DNS API plugin for Technitium DNS Server <https://technitium.com/dns/>

# Requires the following environment variables to be configured:
|
|
#
|
|
# DNS_WEB_URL:
|
|
# - the URL for the Technitium DNS web service dashboard, including protocol
|
|
# and port, e.g. https://dns-server.example.com:53443
|
|
#
|
|
# DNS_API_TOKEN:
|
|
# - An API token can be created interactively in the DNS web service dashboard
|
