API Integration

This page connects your  account to the Trade Apps desktop app, from start to finish. It takes about 15 minutes the first time. After that, you only press Connect once each trading day.

You will move between two places: the desktop app (Brokers page) and the  web platform in your browser. Keep both open.

• Your  trading account, active, and your login details for it.
• The Trade Apps desktop app installed, and your Trade Apps login. Your broker account must already show as a card on the Brokers page. If it is not there, WhatsApp support at 9398840360 — accounts are added by our team.
• Your phone with an authenticator app (Google Authenticator, Microsoft Authenticator or Authy), for the TOTP step.
• Already using this broker on the Trade Apps website? Then you already have an API app. Use the same key and secret here; skip to the TOTP step.

Brokers accept API orders only from an address you have approved, called a static IP. Trade Apps gives you one with your subscription; free-trial accounts get none.

Open the desktop app and click Brokers in the left menu. Find the card for your  account. If the Static IP box says Not assigned yet, click Get static IP next to it, then Get static IP again in the box that asks you to confirm.

If you see the message To use your system IP, leave this field blank, that is only for clients who trade without a static IP. With a subscription, get the static IP.

The box now shows your static IP. If a window titled Whitelist your static IP opens, keep it open while you do the next steps, and click I have whitelisted it only after you have saved the IP at .

Click inside the Static IP box, select the whole address (Ctrl+A) and copy it (Ctrl+C). Then click Copy next to REDIRECT URL — you need both in the next steps.

• Your IP for  is an IPv6 address. It is long, with colons — for example 2402:1f00:8300:… Copy the whole thing.
• Paste only the IP. Never add a port number, and never use your home Wi-Fi or mobile IP.

Open the  web platform in a new tab and log in with your  login details.

Click your profile (the round letter at the top right), then Trading and Data APIs.

Click Generate Access Token / API Key, and make sure the switch on the right is on API Key (not Access Token).

Click + Generate new API Key. Fill Application Name (any name, for example Trade Apps) and Redirect URL (paste the one from Trade Apps). Leave Postback URL empty. Click Generate API Key.

On the same page, open Static IP Setting (click Add IP Setting). Paste your Trade Apps IP in IP Address 1 and save.

Your new app now appears in the list with its API Key and API Secret. Copy both with the copy icons.

The desktop logs in to your broker by itself each morning, so it needs your TOTP key: the long code of letters and digits behind the QR code your broker shows when you turn TOTP on. From it, the desktop makes the same 6-digit code your authenticator app shows.

On the same Trading and Data APIs page, scroll down to Optional Settings. Next to Set-up TOTP, click Add TOTP.

A Setup TOTP panel opens on the right. Click Enable TOTP at the bottom.

 sends an OTP to your registered mobile and email. Type it and click Verify OTP.

Step 1 of the panel shows a QR code and, under it, Enter Setup Code in Authenticator with the key in a box. Copy that code — it is your TOTP key.

Scan the QR code with your authenticator app, type its 6-digit code in Step 2, and click Enable TOTP Login.  shows TOTP enabled for APIs.

• Copy the key, not the 6-digit code. The code changes every 30 seconds; the key never changes.
• Also scan the QR code with an authenticator app on your phone (Google Authenticator, Microsoft Authenticator or Authy). You need its codes for the broker’s own website and app.
• If TOTP was turned on long ago and you did not save the key, reset TOTP to see a new key, and scan the new QR code on your phone too — the old codes stop working.
• The key is as private as your password. Never send it to anyone, including us.

The desktop takes its prices from , and  sends live prices only to accounts with its Data APIs plan. Placing orders is free; the prices are not.

On web..co, open your profile → Trading and Data APIs → the Trading & Data APIs tab. Under Data APIs, click Subscribe to Data APIs. On 9 Nov 2026 it cost Rs 499 + GST per month, taken from your  balance and renewed every 30 days. Check the price on that page before you pay.

The free tier (Trading APIs) is not enough, and Data APIs for Pro Traders is not needed.

Without the plan, orders still go through, but the desktop gets no prices from this broker: Trade Scalper shows (no market-data plan) next to the feed, and a MARKET order is refused because there is no price to check it against. The desktop never borrows prices from another broker.

Go back to the desktop app, Brokers page, your  card. Fill in:

• API KEY (app id) — the API Key from .
• API SECRET (app secret) — the API Secret from .
• Mobile number — the mobile number registered with .
• PIN — your  login PIN.
• TOTP Generator — the TOTP key you copied.
• Access token (optional) — leave empty.
• Paste each value exactly, with no space before or after. Leave User ID as it is — it comes from your Trade Apps account.

Click Connect. It saves what you typed and logs in. The desktop logs in with your mobile number, PIN and TOTP key; no broker page opens. A  session lasts about 24 hours.

When it worked, the grey Not connected label turns green and says Connected till 11:59 pm. Trade Disc and Trade Scalper both use this connection.

What you typed is saved, encrypted, on this computer only. Each trading day, open the Brokers page and press Connect once before the market opens. You do not repeat the setup. On a second computer you type the details once more.

If Connect fails, the reason is written in red on the card, under the labels. Check these in order; most failures are one of the first four.

• Wrong IP, or IP saved in the wrong box. In the  web platform, the IP must be exactly the one the desktop card shows, in the IPv6 box. After changing it, wait 2 minutes, then press Connect again.
• TOTP key wrong. The TOTP box needs the long key from the TOTP setup, not today’s 6-digit code. If in doubt, turn TOTP off and on at the broker, copy the new key, and paste it again.
• Password or PIN changed at the broker. Type the new one in the card and press Connect.
• Redirect URL has a typo or extra space. Click Copy on the card again and paste it fresh at the broker.
• Key and secret swapped, or a space copied with them. Paste each one again into the right box.
• Switch on Access Token instead of API Key. An access token does not work here. Create an API key with the switch on API Key.
• Connected, but no prices. The Data APIs plan is missing or has run out. Renew it on , then press Connect again.
• Still stuck? WhatsApp 9398840360 with a screenshot of the card and the time. Never send your password, PIN, OTP, TOTP key or API secret — we never need them.
