# Resend Request

> FIX message used to request retransmission of messages when a sequence gap is detected.

The Resend Request message is used to request retransmission of messages from the counterparty when a sequence gap is detected. When a sequence gap is detected (i.e., when the incoming message sequence number is greater than expected), a Resend Request should be sent to request retransmission of the missing messages.
