 Every HTTP request made by a homeserver is authenticated using public
 key digital signatures. The request method, target and body are signed
-by wrapping them in a JSON object and signing it using the [JSON signing
-algorithm](/appendices#signing-json). The resulting signatures are added
-as an Authorization header with an auth scheme of `X-Matrix`. Note that
-the target field should include the full path starting with `/_matrix/...`,
-including the `?` and any query parameters if present, but should not
-include the leading `https:`, nor the destination server's hostname.
