The mode section value is either http or tcp, which operates at the faster, but less-aware, level. The option section is either httplog or tcplog. You will prefer httplog over tcplog because when HAProxy encounters a frontend with mode tcp, it will emit a warning and downgrade it to option tcplog.

In the following examples we'll use curl to perform http requests and the jq tool to pretty-print the API responses, but you can use any tool or library for interacting with a RESTful API. You can find your API key (X-Lsw-Auth) in the Customer Portal under API
