Static IP for the Fyers API

Since 1 April 2026, Fyers lets you place API orders only from the static IP saved on your Algo trading app. Older apps were moved to data-only mode, so you activate the new app, enter your fixed IP there and use the new App ID. Fyers' API hosts have IPv6 addresses and an IPv6 address worked in our testing, but confirm in your dashboard before choosing IPv6.

What Fyers checks

From the Fyers API docs and support articles:

• One trading app. An individual account gets one trading app (order placement, static IP required) and any number of non-trading apps for data only.
• Orders only. The static IP is needed only for order placement. Data APIs don't need one.
• New app, new ID. Apps created under the old setup moved to data-only mode from 1 April 2026. The new Algo trading app gets a new App ID (ending in 200) and secret.
• Family sharing. Family members can request a common static IP through Fyers support with a declaration.

The Fyers pages we checked don't say how many IPs you can add or how often you can change them. Check the API dashboard itself.

IPv4 or IPv6 for Fyers

On the network side, IPv6 is fine: both api-t1.fyers.in and socket.fyers.in have IPv6 addresses. Fyers doesn't say in its docs whether the static IP field takes IPv6, but Fyers accepted an IPv6 address in our testing (July 2026), and it's on our list of brokers that support IPv6. Try the IPv6 address in the dashboard first. If it's refused, use IPv4.

How to register your IP with Fyers

1. Get your fixed IP's proxy details: host, port, username and password.
2. Check the exact exit address: curl -x http://USER:PASS@HOST:PORT https://ifconfig.co
3. Open the Fyers API dashboard, click Algo trading app, enter the static IP and redirect URL, select permissions and click Activate.
4. Note the new App ID and secret, and use them in your code.

Send Fyers orders through the fixed IP

The synchronous fyers-apiv3 client uses requests, which reads the standard proxy environment variables. Set them before creating the client, in a process that runs only your bot:

import os

PROXY = os.environ["PROXY_URL"]  # http://USER:PASS@HOST:PORT
for v in ("HTTPS_PROXY", "https_proxy", "HTTP_PROXY", "http_proxy"):
    os.environ[v] = PROXY  # requests in this process now uses the fixed IP

from fyers_apiv3 import fyersModel

fyers = fyersModel.FyersModel(
    client_id=os.environ["FYERS_APP_ID"],
    token=os.environ["FYERS_ACCESS_TOKEN"],
    is_async=False,
    log_path="",
)

Keep is_async=False. In fyers-apiv3 3.2.1 the async client uses aiohttp with default settings, and aiohttp ignores proxy environment variables, so async orders would leave from your normal IP and be rejected. The full Fyers proxy guide on GitHub covers token generation, a sample order and verification.

Common Fyers errors

• Orders rejected, profile works. Profile isn't IP checked. Compare the exit IP from inside the bot with the app's IP, and make sure you're using the new App ID ending in 200.
• 403 errors. These can come from an expired or wrong token as well as an IP mismatch, so check both.
• Works in a test script, fails in the bot. Look for is_async=True, or proxy variables set after the client was created.
• 407 Proxy Authentication Required. Wrong proxy credentials, or a password with @ or : that needs URL-encoding.
