Hi,
To use a proxy in the API Connect plugin will use the proxy defined via http_proxy/https_proxy env variables. I've confirmed these are used by the libraries in the API Connect plugin.
So if you have done so already you would need to set up http/https proxy by adding these to DATADIR/bin/env-site.sh as shown here: https://doc.dataiku.com/dss/latest/operations/proxies.html#proxy-configuration-for-python-and-r-proc...
. Also make sure to set no_proxy=localhost,127.0.0.0,<any other ips/hostnames that should not go through the proxy>
Let me know if you have any questions.
