# Options passed from /etc/config/ddns:
# Domain - the domain name managed by DigitalOcean (e.g. example.com)
# Username - the hostname of the domain (e.g. myrouter)
# Password - DigitalOcean personal access token (API key)
# Optional Parameter - the API domain record ID of the hostname (e.g. 21694203)

# Use the following command to find your API domain record ID (replace TOKEN and DOMAIN with your own):
# curl -X GET -H 'Content-Type: application/json' \
# 	-H "Authorization: Bearer TOKEN" \
# 	"https://api.digitalocean.com/v2/domains/DOMAIN/records"
