HTTP Request

POST: /exchange/index

request parameters

parameter name required type description
common parameter Yes JSON common parameter refer to: signature (sign), version (version), merchant ID (app_id), time (time)
user_id No string Merchant user id (required for merchants with risk control enabled)
source_coin yes string exchange coin
target_coin yes string exchange target coin
amount yes string amount of currency exchanged
trade_id Yes string Merchant-side transaction unique ID (up to 32 characters in length. Recommended format: year, month, day, hour, minute, second + 6-digit random number Case column: 20200311202903000001)
limit_price no string limit price (if type=0, this field is required). The minimum exchange price when exchanging stable coins, or the maximum exchange price when exchanging virtual currency.
type yes int exchange mode (1 closing mode / 0 general exchange), default 1. Generally, a pending order is placed under the condition that the minimum price is met. There may be some successes and some failures. If the exchange is not successful within a certain period of time, the order will be cancelled. The closing mode is that the order will be successfully placed, regardless of the impact of slippage, and will continue to try to place the order on the exchange regardless of the price.
max_time no int unit second - maximum redemption time - the redemption will be stopped if the redemption will be completed (the general mode only takes effect)

Response parameter description

parameter name type description
status int status code
