portal2 2.8.1 API documentation
There have been some requests that I make portal2‘s API documentation available online and not just available at LANs. So I have published a copy of the portal2 API v2.8.1. This covers the (at the time of writing) current version of portal2’s HTTP GET and XMLRPC APIs.
Unfortunately, there’s no online “simulator” available, but that should be trivial for someone to write if they’re testing their program.
