# Refresh a payin quote

`POST /pay/{id}/rfq`

Refreshes an existing pay quote identified by its transaction ID.
This is used when a previously issued quote is near to expire and the platform wants a new rate for the same deposit address.
Already expired quotes can't be refreshed.

The response format is identical to `POST /pay/rfq` — it returns an updated rate, expiry timestamp, and the same deposit address.

## Path parameters

- `id` string, uuid, required

## Headers

- `X-SCX-SIGNED` string, required
- `X-SCX-TIMESTAMP` string, required

## Request body

- PostPayRfqByIdBody
  - `participant_code` string, required — The participant code for the shopper whose quote is being refreshed
