Request Authorization and API call example

The resulting API KEY should be sent in the X-API-KEY header with each API call. An additional parameter signature in the X-API-SIGN header is also required.

To get the signature parameter, you must use your SECRET KEY as the HMAC SHA256 operation key and totalParams as its value.

totalParams is defined as the query string concatenated with the request body

Example:

queryString:
from=ETH&to=BTC

HMAC SHA256 signature:

[linux]$ echo -n "from=ETH&to=BTC" | openssl dgst -sha256 -hmac "qVeyDheFpFavNy8kSy1vJc9SG8FZnFeWnJDf9ACx"
(stdin)= 937e81878116673549260c1f174483a6e061d1e19d4f9ffda56decdd8b2a9182

curl command:

(HMAC SHA256)
[linux]$ curl -H "X-API-KEY: pjFBsaK1HJwQYjZQyy8heEnyyt2G4KyfvDF29lMP" -H "X-API-SIGN: 937e81878116673549260c1f174483a6e061d1e19d4f9ffda56decdd8b2a9182" -d "from=ETH&to=BTC" -X POST https://fixedfloat.com/api/v1/getPair
