How to use API key

Before calling private endpoint you will need to generate three headers:

X-Auth-Apikey - API key (from previous step)

X-Auth-Nonce - A nonce is an arbitrary number that can be used just once. You MUST use a millisecond timestamp in UTC time. Read more about it here.

Example:

date +%s%3N
1584087661035

X-Auth-Signature - HMAC-SHA256 signature calculated using a concatenation of X-Auth-Nonce and X-Auth-Apikey. Hexdigest secret is your API Secret.

Sample Request below:

curl -X GET https://trade.nebulaecn.com/api/v2/backend/account/balances \
-H "X-Auth-Apikey: "Your Api Key" \
-H "X-Auth-Nonce: "Nonce" \
-H "X-Auth-Signature: "HMAC-SHA256 signature"
