-# Client-Server API Extensions
-
-Server administrators can set special account data to change how the Client-Server API behaves for
-their clients. Setting the account data, or having it already set, as a non-admin has no effect.
-
-All configuration options can be set through the `io.element.synapse.admin_client_config` global 
-account data on the admin's user account. 
-
-Example:
-```
-PUT /_matrix/client/v3/user/{adminUserId}/account_data/io.element.synapse.admin_client_config
-{
-    "return_soft_failed_events": true
-}
-```
-
-## See soft failed events
-
-Learn more about soft failure from [the spec](https://spec.matrix.org/v1.14/server-server-api/#soft-failure).
-
-To receive soft failed events in APIs like `/sync` and `/messages`, set `return_soft_failed_events`
-to `true` in the admin client config. When `false`, the normal behaviour of these endpoints is to
-exclude soft failed events.
-
