Static IP for Dhan HQ API

Dhan HQ checks the source IP on order APIs. You can register more than one address, but a rotating home IP still burns slots. One dedicated IPv4 is the stable option.

How to whitelist a static IP

2. In web.dhan.co open API profile → Static IP and paste the address.
3. Set HTTP proxy host + port 443 on REST and WebSocket clients.
4. Verify egress with api.ipify.org before the first live order.
