Fyers API IP Not Whitelisted — OAuth Origin Mismatch Fix

Fyers API IP Not Whitelisted — OAuth Origin Mismatch Fix

Fyers v3 IP whitelist not working after OAuth? Complete login through the same HTTP proxy 443 you use for orders, then save the dedicated IPv4 on myapi.fyers.in.

Where Fyers stores the IP

myapi.fyers.in → your v3 app → IP whitelist. Confirm IPv6 in that field before you allocate an IPv6-only plan.

The OAuth trap

Most Fyers errors after “it worked in Postman” come from generate_authcode / token exchange on the raw machine IP, then fyersModel calls through a proxy. Finish the entire OAuth loop with HTTPS_PROXY already set, or use a small local callback that itself uses the proxy.

Dedicated page: /brokers/fyers. Use port 443 on Jio/Airtel; 8088 will time out.
