Our production endpoint configuration parameters:

We recommend using our SDK or listed client libraries depending on your language requirements:

Security

Stunnel configuation:

[COINAPI]
client = yes
accept = 3301
connect = fix.coinapi.io:3302
verify = 2

Communication with our FIX gateway is secured by TLS protocol if you are using the encrypted port. If your FIX protocol implementation does not support establishing a connection over a secure channel, you must use a proxy between your client and our FIX gateway to unbundle encryption or use unencrypted port. We recommend stunnel (opens in a new tab) as a proxy if a secure connection can't be established directly from your client and you can't allow the unencrypted traffic.
