Request Signing

Generate HMAC-SHA256 signature:

signature = HMAC-SHA256(api_secret, timestamp + method + path + body)

Headers

X-API-Key: your_api_key
X-API-Timestamp: 1705312200000
X-API-Signature: abc123...

Example

import hmac
import hashlib
import time

timestamp = str(int(time.time() * 1000))
message = f"{timestamp}POST/api/sdk/orders{body}"
signature = hmac.new(
    api_secret.encode(),
    message.encode(),
    hashlib.sha256
).hexdigest()
