# Joker.com API for acme.sh
#
# This script adds the necessary TXT record to a domain in Joker.com.
#
# You must activate Dynamic DNS in Joker.com DNS configuration first.
# Username and password below refer to Dynamic DNS authentication,
# not your Joker.com login credentials.
# See: https://joker.com/faq/content/11/427/en/what-is-dynamic-dns-dyndns.html
#
# NOTE: This script does not support wildcard certificates, because
# Joker.com API does not support adding two TXT records with the same
# subdomain. Adding the second record will overwrite the first one.
# See: https://joker.com/faq/content/6/496/en/let_s-encrypt-support.html
#   "... this request will replace all TXT records for the specified
#    label by the provided content"
