From 2341032cf2d031e58710d82c9ee1d2360f9b82f9 Mon Sep 17 00:00:00 2001 From: jejo86 <28619134+jejo86@users.noreply.github.com> Date: Wed, 13 Jul 2022 20:33:33 +0200 Subject: Document advising against publicly exposing the Admin API and provide a usage example (#13231) * Admin API request explanation improved Pointed out, that the Admin API is not accessible by default from any remote computer, but only from the PC `matrix-synapse` is running on. Added a full, working example, making sure to include the cURL flag `-X`, which needs to be prepended to `GET`, `POST`, `PUT` etc. and listing the full query string including protocol, IP address and port. * Admin API request explanation improved * Apply suggestions from code review Update changelog. Reword prose.
