Accepts a quote created via [Create Conversion](/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, as `/` — display names, not currency codes (e.g. `USDT (TRX)/BRL (PIX)`) | | `settlement_eta` | string | Confirmed settlement time (RFC 3339) | | `wallet_id` | string | Destination wallet, echoed back when the payout is crypto | | `pix_key` | string | Destination Pix key, echoed back when the payout is BRL | | `reason` | string | Empty on `200`; carries the explanation on a refusal or failure | This is the one endpoint in the API that returns `state`, because `state` is what carries the outcome of the accept. Everywhere else, read `status` / `substatus` instead. 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](/api-reference/conversions/get) or the `webhook` to track it. ## Outcomes `POST /v2/rfq/accept` is the only committing operation in the conversion flow, so it has the widest set of outcomes. Every one of them is listed here. | HTTP | State | Meaning | Retry? | | --------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------ | --------------------- | | `200 OK` | `DONE` | Accepted. `amount_from`, `amount_to`, `rate`, `settlement_eta` are populated | Done | | `202 Accepted` | — | **Still being evaluated — this is not an acceptance.** `reason` is deliberately empty: it is a wait, not a refusal | Yes, by re-reading | | `400 Bad Request` | — | Invalid JSON, unknown field, empty `rfq_id`, or `settlement_day` outside `d0` / `d1` | No | | `401 Unauthorized` | — | Missing or invalid `api-key` | No | | `404 Not Found` | — | The conversion does not exist, or belongs to another account. The two cases are deliberately indistinguishable | No | | `409 Conflict` | `EXPIRED` | The rate expired and the quote was renewed — re-read the conversion and resubmit with the new rate | Yes, after re-reading | | `410 Gone` | `DEPRECATED` | The renewal window closed — create a new conversion | No | | `422 Unprocessable Entity` | `REFUSED` or `ERROR` | Refused. `reason` carries the cause: insufficient balance, D0 unavailable, or a limit ceiling | No | | `503 Service Unavailable` | — | The rate provider is unavailable. **Nothing was decided** — the conversion is still in `QUOTE` and can be accepted again | Yes | | `500 Internal Server Error` | — | Failed to re-read the conversion or its attributes | Sometimes | **A `202` is not a success.** It means the accept is still being evaluated and no decision has been recorded. Do not treat it as confirmation and do not resubmit the accept — re-read [Get Conversion](/api-reference/conversions/get) or wait for the webhook until you reach a terminal outcome. When a `422` is caused by a limit ceiling rather than balance, `GET /v2/rfq/{id}` exposes `limit_block_source` to tell you which gate blocked it — `operational` for the desk ceiling, `compliance` for the KYB tier. The field is absent when the refusal was for insufficient balance. `503` and `202` are safe to retry. `409` needs a re-read first. `410` and `422` are final for that `rfq_id`. **Status codes:** `200`, `202`, `400`, `401`, `404`, `409`, `410`, `422`, `500`, `503` ```bash cURL theme={null} curl -X POST https://checkout.noxpay.io/v2/rfq/accept \ -H "api-key: " \ -H "Content-Type: application/json" \ -d '{ "rfq_id": "NOXabc123...", "settlement_day": "d0", "wallet_id": "..." }' ``` ```python Python theme={null} import requests response = requests.post( "https://checkout.noxpay.io/v2/rfq/accept", headers={ "api-key": "", "Content-Type": "application/json", }, json={ "rfq_id": "NOXabc123...", "settlement_day": "d0", "wallet_id": "...", }, ) print(response.json()) ``` ```javascript Node.js theme={null} const response = await fetch("https://checkout.noxpay.io/v2/rfq/accept", { method: "POST", headers: { "api-key": "", "Content-Type": "application/json", }, body: JSON.stringify({ rfq_id: "NOXabc123...", settlement_day: "d0", wallet_id: "...", }), }); const data = await response.json(); ``` ```json 200 theme={null} { "rfq_id": "NOXabc123...", "state": "DONE", "amount_from": 1000.0, "amount_to": 5050.0, "rate": 5.050, "quote_pair": "USDT (TRX)/BRL (PIX)", "settlement_eta": "2026-07-01T19:00:00Z" } ``` ```json 409 theme={null} { "state": "EXPIRED", "reason": "Rate expired and was renewed — fetch the latest quote before retrying" } ``` ```json 410 theme={null} { "state": "DEPRECATED", "reason": "Renewal window closed — create a new conversion" } ``` ```json 422 theme={null} { "state": "REFUSED", "reason": "Insufficient balance" } ``` ```json 503 theme={null} { "state": "QUOTE", "reason": "forex rate unavailable" } ```
