      summary: Send a transaction
      description: |-
        Push messages representing live activity to another server. The destination name
        will be set to that of the receiving server itself. Each embedded PDU in the
        transaction body will be processed.

        The sending server must wait and retry for a 200 OK response before sending a
        transaction with a different `txnId` to the receiving server.

        Note that events have a different format depending on the room version - check
        the [room version specification](/rooms) for precise event formats.
