brokerkit-groww 1.0.2

Groww adapter for BrokerKit.

brokerkit-groww

BrokerKit's Groww adapter — wraps the official growwapi SDK behind BrokerKit's broker-agnostic interfaces (auth, instruments, orders, portfolio, market data, historical candles, streaming).

You write strategy code against brokerkit-core's types; this package is what makes "groww" work with create_broker(...).

Install

pip install brokerkit-core brokerkit-groww

Prerequisites (Groww dashboard)

1. TOTP credentials — Groww's API auth is TOTP-only. Get your api_key + totp_secret from the Groww API dashboard.
2. Static IP registration ("Add static IP" on the dashboard) — required by SEBI rules for order placement. Without it, orders.place_order() fails with an IP-rejection error (reads — holdings, instruments — still work fine).
3. Trading API subscription (₹499/month + taxes) — required for market data (quotes, LTP, OHLC, historical candles) and streaming. Without it, those calls raise BrokerKitError("Access forbidden...").

Auth, instrument lookup, and portfolio reads work without either of the above.

Quick start

import asyncio
import os

from brokerkit import Exchange, Segment, create_broker


async def main():
    broker = await create_broker(
        "groww",
        totp_key=os.environ["GROWW_API_KEY"],
        totp_secret=os.environ["GROWW_TOTP_SECRET"],
    )

    instruments = await broker.instruments.fetch_instruments()
    reliance = next(
        i for i in instruments
        if i.symbol == "RELIANCE" and i.exchange == Exchange.NSE and i.segment == Segment.CASH
    )

    quote = await broker.market.get_quote(reliance)
    print("LTP:", quote.last_price)

    holdings = await broker.portfolio.holdings()
    print("Holdings:", holdings)

    await broker.close()


asyncio.run(main())

Using create_broker("groww", ...) (rather than importing GrowwBroker directly) keeps your strategy code broker-agnostic — swapping to another broker later is a one-line change. Direct import (from brokerkit_groww import GrowwBroker; await GrowwBroker.create(...)) works identically if you don't need that.

A fuller runnable version lives in examples/basic/main.py.

What you get on broker

Every provider below is an instance of the corresponding ABC from brokerkit-core (brokerkit.interfaces), so the same calls work against any future broker adapter.

broker.instruments — InstrumentProvider

instruments = await broker.instruments.fetch_instruments()  # list[Instrument]

Downloads and normalizes Groww's full instrument master (~145k rows) on every call — no caching in the framework. Filter/search app-side.

broker.orders — OrderProvider

from decimal import Decimal
from brokerkit import OrderRequest, OrderType, Product, TransactionType

order = await broker.orders.place_order(OrderRequest(
    instrument=reliance,
    transaction_type=TransactionType.BUY,
    order_type=OrderType.LIMIT,
    quantity=1,
    product=Product.CNC,
    price=Decimal("2500"),
))

await broker.orders.modify(order.order_id, reliance.segment, price=Decimal("2510"))
await broker.orders.cancel(order.order_id, reliance.segment)
await broker.orders.get_order(order.order_id, reliance.segment)
await broker.orders.list_orders()

No client-side pre-validation (freeze qty, buy/sell allowed, etc.) — Groww rejects invalid orders and the rejection reason comes back as Order.status_message.

broker.portfolio — PortfolioProvider

await broker.portfolio.holdings()   # list[Holding] — demat-level, ISIN-identified
await broker.portfolio.positions()  # list[Position] — per trade, today's book

broker.market — MarketDataProvider

await broker.market.get_quote(reliance)                 # Quote — LTP, OHLC, depth, circuits
await broker.market.get_ltp([reliance, infy, tcs])       # dict[symbol, Decimal]
await broker.market.get_ohlc([reliance, infy])           # dict[symbol, Ohlc]

get_ltp/get_ohlc batch and chunk internally (Groww allows up to 50 symbols per call, one segment at a time) — pass as many instruments as you want.

from datetime import date

chain = await broker.market.get_option_chain(nifty_index, expiry=date(2026, 7, 21), strike_count=10)
print(chain.underlying_ltp)
for s in chain.strikes:
    print(s.strike, s.call.ltp if s.call else None, s.call.greeks.delta if s.call and s.call.greeks else None)

expiry is required — Groww's endpoint has no "nearest expiry" convenience and no strike-count filter either (strike_count is accepted for interface parity with Fyers but ignored — Groww always returns the full chain). Unlike Fyers, Groww's greeks include rho — but Groww's contracts have no bid_price/ask_price at all (confirmed absent via both the official docs' field list and a third-party typed SDK, not guessed — always None here; Fyers' do have them, useful for a liquidity check before trading). Not yet live-tested — blocked by the same paid live-data subscription that blocks get_quote/get_ltp/get_ohlc/candles; mapper unit-tested against a real captured response shape (cross-verified via a third-party typed Go SDK, since Groww's own docs don't show the exact JSON nesting).

broker.historical — HistoricalDataProvider

from datetime import datetime, timedelta

candles = await broker.historical.get_candles(
    reliance,
    start=datetime.now() - timedelta(days=7),
    end=datetime.now(),
    interval_minutes=1440,  # daily
)

broker.streaming — StreamingProvider

async def on_tick(tick):
    print(tick.symbol, tick.ltp)

await broker.streaming.subscribe_ltp([reliance], on_tick)
# ... later
await broker.streaming.unsubscribe_ltp([reliance])
await broker.streaming.close()

Callback can be sync or async. Requires instrument.exchange_token to be set (comes from fetch_instruments()).

Auth & token lifetime

Groww's TOTP flow has three layers, easy to mix up:

• TOTP secret (totp_secret) — never expires. Used to generate a fresh 6-digit code every 30 seconds.
• TOTP code — lives 30 seconds, but only matters at login; it's consumed once to fetch the access token and then discarded.
• Access token — the thing that actually authenticates every API call. Expires daily at 6 AM IST.

You don't need to think about any of this during normal use: GrowwBroker runs a background refresh loop (started in create(), stopped in close()) that sleeps until the token's known 6 AM IST expiry, re-logs in, and swaps the token in place — every provider (orders, portfolio, market, ...) picks it up automatically since they all share one underlying client. A long-running bot survives across days without manual re-auth. If a refresh attempt fails (network blip), it retries after 60s rather than dying silently.

Errors

Every growwapi exception is translated into a brokerkit exception before it reaches your code — you never need to catch growwapi.groww.exceptions.* directly:

from brokerkit import BrokerKitError, OrderError, StreamingError

try:
    await broker.orders.place_order(request)
except OrderError as e:
    print("order failed:", e)

Multiple accounts

Each GrowwBroker instance owns its own client and providers, so multiple accounts (Groww or mixed with future brokers) run independently via BrokerManager:

from brokerkit import BrokerManager

manager = BrokerManager()
await manager.add("primary", "groww", totp_key=k1, totp_secret=s1)
await manager.add("secondary", "groww", totp_key=k2, totp_secret=s2)

await manager["primary"].orders.place_order(request)
await manager.close_all()
