`MsgType(35)=ResendRequest(2)`

Direction: **Both directions**.

Request recovery of a range of message sequence numbers.

Market-data sessions advance past missing messages using sequence-reset gap fills rather than replaying application messages. Order-entry sessions can replay retained application messages.

## Field Layout

See [FIX Message Layouts](/reference/fix-message-layouts) for field ordering and presence rules.

| Field | Type | Presence | Behavior |
| --- | --- | --- | --- |
| `BeginSeqNo(7)` | [`SEQNUM`](/reference/fix-data-types#seqnum) | Required |  |
| `EndSeqNo(16)` | [`SEQNUM`](/reference/fix-data-types#seqnum) | Required |  |
