#
# This script is using PDNS Manager's API to update TXT record since giving API
# access to PowerDNS API itself is not possible for a single domain (or record).
#
# Before first run; export these variables or failure is imminent.
#
# export PDNS_MANAGER_URL=https://pdnsmanager.domain.nx
# export PDNS_MANAGER_RECORDID=
# export PDNS_MANAGER_PASSWORD=
#
# Then run:
#
# acme.sh --issue --staging --dns dns_pdnsmanager -d domaintovalidate.nx
#
# Remember to remove --staging in production
#

# Usage: dns_pdnsmanager_add   _acme-challenge.www.domain.com   "XKrxpRBosdIKFzxW_CT3KLZNf6q0HG9i01zxXp5CPBs"
