Hello SmartAPI Support Team,

I am integrating Angel One SmartAPI historical market data into my CPMarketIQ application.

My login and token generation are successful. My current public IP also matches the registered Primary Static IP.

However, the historical candle API returns HTTP 403 Forbidden.

Request details:

Exchange: NSE

Instrument: SBIN

Interval: FIVE_MINUTE

Requested date: 12 October 2026

API endpoint: /rest/secure/angelbroking/historical/v1/getCandleData

HTTP status: 403

Historical data retrieval previously succeeded for 14 October 2026.

Could you please check whether this is caused by historical API permissions, rate limiting, IP restrictions, or another server-side security rule?

Thank you.
