#Here is a sample custom api script.
#This file name is "dns_bookmyname.sh"
#So, here must be a method   dns_bookmyname_add()
#Which will be called by acme.sh to add the txt record to your api system.
#returns 0 means success, otherwise error.

# BMN urls:

# https://BMN_USER:BMN_PASSWORD@www.bookmyname.com/dyndns/?hostname=_acme-challenge.domain.tld&type=txt&ttl=300&do=remove&value="XXXXXXXX"'

# Output:
