+description: |
+  Matrix homeservers use the Federation APIs (also known as server-server APIs)
+  to communicate with each other. Homeservers use these APIs to push messages in
+  real-time, retrieve historic messages, and query profile or presence
+  information about users on other servers. The APIs are implemented over HTTPS,
+  with authentication provided by public key signatures both at the TLS
+  transport layer and in HTTP Authorization headers.
+
+  There are three main kinds of communication that occur between
+  homeservers:
+
+  Persistent Data Units (PDUs):
+  These events are broadcast from one homeserver to any others that have
+  joined the same room (identified by Room ID). They are persisted in
+  long-term storage and record the history of messages and state for a
+  room.
+
+  Like email, it is the responsibility of the originating server of a PDU
+  to deliver that event to its recipient servers. However PDUs are signed
+  using the originating server's private key so that it is possible to
+  deliver them through third-party servers.
+
+  Ephemeral Data Units (EDUs):
+  These events are pushed between pairs of homeservers. They are not
+  persisted and are not part of the history of a room, nor does the
+  receiving homeserver have to reply to them.
+
+  Queries:
+  These are single request/response interactions between a given pair of
+  servers, initiated by one side sending an HTTPS GET request to obtain
+  some information, and responded by the other. They are not persisted and
+  contain no long-term significant history. They simply request a snapshot
+  state at the instant the query is made.
+
+  EDUs and PDUs are further wrapped in an envelope called a Transaction,
+  which is transferred from the origin to the destination homeserver using
+  an HTTPS PUT request.
