If we accept the Fyers API authorization request when using the direct.fyers.in or alerts.fyers.in services, will the client be disqualified from the Fyers 30 day challenge brokerage refund scheme?

Hey George,

You'll not be eligible for 30 Day Challenge refund only if you're using FYERS trading API whereas you'll not be affected for granting the one-time permission to access direct.fyers.in46 or alerts.fyers.in40 services. 

Hope this helps!
