You can create multiple APIs, Name each API accordingly so that they are identifiable and can be managed accordingly.
Check your registered email for a confirmation email, click on the link in the email and the API should be created. If you don't see any emails from Binance, check out this help article to troubleshoot receiving a confirmation email.
Use the scan QR code function on CryptoHero to add the API immediately or if you are on the same device, you can use the copy and paste function for both the API Key and the Secret Key. Make sure you use unrestricted IP address.
Be sure to grant "Enable Trading" permission. NEVER NEVER NEVER grant "Withdrawal" permission to our API.
