Broker Auth: Dhan¶

Open In Colab

Authenticate and place a demo order via DhanHQ v2 over your static IP.

Part 03 of 20 in the ServLoci algo/options trading notebook series — full index in notebooks/README.md.

Setup¶

# Get your dedicated static IPv6 + SOCKS5 credentials free:
#   https://comm.servloci.in/register        (or /auth/google?free=1 for an instant trial)
# Your api_key / api_secret pair shows up in the portal after signup:
#   https://comm.servloci.in/user
!pip install -q "requests[socks]"
!curl -sL https://comm.servloci.in/sdk/servloci.py -o servloci.py

import os
from servloci import ServLoci

SERVLOCI_API_KEY = os.environ.get("SERVLOCI_API_KEY", "dhan:1000000001")   # broker:client_id
SERVLOCI_API_SECRET = os.environ.get("SERVLOCI_API_SECRET", "")            # from the portal — leave blank to run this notebook in demo mode

sl = None
if SERVLOCI_API_SECRET:
    sl = ServLoci(api_key=SERVLOCI_API_KEY, api_secret=SERVLOCI_API_SECRET)
    print("ServLoci configured:", sl.host, sl.port)
else:
    print("SERVLOCI_API_SECRET not set — running in demo mode (no live proxy calls).")

Support level: Assisted review — DhanHQ v2 API access is granted via a support ticket; mention your ServLoci IPv6 in the request.

if sl:
    sl.attach()  # BEFORE importing dhanhq — it creates a requests.Session at import time
    from dhanhq import dhanhq

    dhan = dhanhq(client_id=os.environ.get("DHAN_CLIENT_ID", ""), access_token=os.environ.get("DHAN_ACCESS_TOKEN", ""))
    print("Dhan client ready:", dhan.client_id)
    # order = dhan.place_order(security_id="1333", exchange_segment=dhan.NSE, transaction_type=dhan.BUY,
    #                           quantity=1, order_type=dhan.MARKET, product_type=dhan.INTRA, price=0)
else:
    print("Demo mode — set SERVLOCI_API_SECRET above to run this against your Dhan account.")
