Hello Sir,

I am new user to use CCXT on my project. I have a issue on some of functions like fetch my orders and Fills from Kucoin. When I these functions it throw error like "AuthenticationError: KC-API-KEY not exists".

My code is as below please provide solution....

`var kucoinData = new ccxt.kucoin({
apiKey: 'mykey',
secret: 'secret',
password:'password'
});

var Data = await kucoinData.fetchMyTrades();

Please see above code and provide solution where I wrong in code....

Hello!

AuthenticationError: KC-API-KEY not exists

↑ That is the message you get from the KuCoin exchange directly. So, you want to check if your keys are correct. If you are 100% sure that the keys are correct – you may want to address this question to the KuCoin tech support.

The apiKey should be a string like '5e90...9925' (24 symbols without dashes).
The secret should be a string '5ce8a082-01ee-...-bc8d-ccb0dbfc0f85' (36 symbols with dashes).
The password is your API key password with KuCoin.

Another common pitfall is using the testnet keys with the actual real API – not all exchanges have the same keys for the testnet and the real exchange API.

Creating a new keypair can also help if your previous keypair is very old (since KuCoin updates the API over time).

Let us know if that does not help.

@jaydevvaghela943 if you are using testnet keys – you should switch to the testnet as well.

1. You can use testnet keys with testnet API
2. You can not use testnet keys with real API
3. You can not use real keys with testnet API
4. You can use real keys with real API

var kucoinData = new ccxt.kucoin({
    apiKey: 'mykey',
    secret: 'secret',
    password:'api_passphrase'
});
kucoinData.urls['api'] = kucoinData.urls['test']  // ←--------- if you're using testnet keys
var Data = await kucoinData.fetchMyTrades();
console.log(Data);
