I have an API end point which fetches traffic statistics from a Network Packet Broker, its curl equivalent command is:
curl -s -k -X 'POST' 'https://10.0.0.1:8000/stats' -H ' accept:application/json' -H 'Authorization: Basic jwdebgfuwibwdb' -H 'Content-Type: application/json' -d '{"port": , "stat_name":["np_current_pass_rate_bits"] }'

to convert this command into equivalent filebeat.yml format using httpjson input, how to give -d '{"port": , "stat_name":["np_current_pass_rate_bits"] }' argument of the curl command in the filebeat.yml file
