# Callback

`POST /api/mixpay/callback`

## Request

- Base URL: `https://api.nullprint.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.nullprint.ai/api/mixpay/callback`
- Auth: none declared

MixPay 回调(只带 orderId / traceId / payeeId,无签名):只当「去查一下」,入账全靠 verify 回查。
终态回 200 {"code":"SUCCESS"} 让它别再推;未定回 202 {"code":"PENDING"} 让它按重试表再推(RoamProxy 跑通的做法)。
不受 MIXPAY_ENABLED 影响(关开关后已建的单付了也要入账);nginx 只放行 52.198.117.57(spec §8)。

## Response `200`

Successful Response

- unknown
