# Retry failed orders in a multiswap

`POST /exchanges/multi/{multiId}/retry`

Retry a failed multiswap bundle. Only possible while the orders are within 30 minutes
of creation (deposit addresses still valid) — the existing UserOp is reset to PENDING and
`txData` (same shape as POST multi/{multiId}/tx/build) is returned so the frontend can
re-sign and submit immediately.

After 30 minutes, or for REFUNDED orders, this returns 400 — use POST /multi/recovery
to withdraw the stuck funds instead.

## Path parameters

- `multiId` string, required

## Request body

- RetryFailedOrdersRequest — Request body for POST /exchanges/multi/{multiId}/retry
