How to get apisix to POST to an endpoint with preconfigured auth and query parameters

[chrislawso]

I have an endpoint on lan ip that requires auth and a specific query parameter that I use to trigger actions:
https://username:password@ip.ip.ip.ip:80/api?do=start&Location=one&Key=12345

How can I configure apisix so that when someone performs a page load on apisix wan interface with no auth and with no query parameters ie
https://apisix-fqdn-url.com/test
then apisix would perform a POST or curl of a preconfigured url
https://username:password@ip.ip.ip.ip:80/api?do=start&Location=one&Key=12345

Thank you
