# Accept Conversion

> POST /v2/rfq/accept — accept an existing quote, choosing the settlement day and destination.

Accepts a quote created via [Create Conversion](/noxpay-docs-v2/api-reference/conversions/create), locking in the rate and scheduling delivery. The balance in `from_currency` must be available at the moment of accept — it is not reserved when the quote is created.

## Request body

| Field            | Type   | Required    | Description                                  |
| ---------------- | ------ | ----------- | -------------------------------------------- |
| `rfq_id`         | string | Yes         | ID returned by Create Conversion             |
| `settlement_day` | string | Yes         | `"d0"` or `"d1"`                             |
| `wallet_id`      | string | Conditional | Destination crypto wallet ID (crypto payout) |
| `pix_key`        | string | Conditional | Destination Pix key (BRL payout)             |

## Response `200 OK` (accepted)

| Field            | Type   | Description                          |
| ---------------- | ------ | ------------------------------------ |
| `rfq_id`         | string | ID of the conversion                 |
| `state`          | string | `DONE` once accepted                 |
| `amount_from`    | float  | Confirmed amount sent                |
| `amount_to`      | float  | Confirmed amount to be received      |
| `rate`           | float  | Confirmed rate                       |
| `quote_pair`     | string | Quote pair identifier                |
| `settlement_eta` | string | Confirmed settlement time (RFC 3339) |

A `200` here means the trade is locked and delivery is scheduled — it does not mean funds have already landed. Delivery completes at `settlement_eta`; see [Get Conversion](/noxpay-docs-v2/api-reference/conversions/get) or the `webhook` to track it.
