'amount':'0.02'



Parameter string:
amount=0.02&api_key=apiKey&market=BTC_USDT&price=50&side=1


Note: The secretKey must be generated to generate the MD5 signature. Add the secret_key to the generated string to generate the final string.


Final signature string
:amount=0.02&api_key=apiKey&market=BTC_USDT&price=50&side=1&secret_key=secretKey



MD5 signature：
