Broker Setup Guides / Fyers

Fyers

Add and validate your Fyers account in QUANT LEVELS.

You must enable "External 2FA TOTP" at myaccount.fyers.in/ManageAccount first and note the TOTP key shown - Fyers' own authenticator app TOTP will not work for API login, it has to be this separately-generated external key.

Step 1 - Create an app

  1. Create an app at fyers.in/web/api-dashboard/user-apps.
  2. Fill in the app form with:
    FieldValue
    Redirect URLhttps://quantlevelsdevloper.in/auth/fyers
    Postback URLhttps://quantlevelsdevloper.in/postback/fyers?key=jByKSan5riiFoxHxtetuI2dkBRkOA_dm
    Postback URL is optional on Fyers' form, but paste it anyway - it's a safety net for slave-order status updates.
  3. Copy the generated App ID (looks like "L9NY305RTW-100") and Secret Key.

Step 2 - Add the account

  1. Go to Accounts → Add New Account.
  2. Select Broker as Fyers.
  3. Enter your Fyers Client ID (e.g. "TK01248"), 4-digit login PIN, the External 2FA TOTP Secret Key from Step 1, App ID and Secret Key.
  4. Save. Your access token auto-refreshes every day.

Common Issues

TOTP always rejected, even freshly copied

This almost always means the regular Fyers-app authenticator TOTP was used instead of the separate "External 2FA TOTP" key - go back to myaccount.fyers.in/ManageAccount and generate/copy that specific key.

Login works but no live data shows

Fyers' fund/position/holding endpoints can occasionally be slow to reflect a fresh login - give it the next 30-second refresh cycle before assuming something's wrong.

Copy trading on Fyers

Fyers' postback doesn't reliably cover manually-placed trades, so master detection for Fyers uses a live streaming connection we maintain per master account.
