I am using the code below to fetch NIFTY option data. While the Expiry date and format are also correct I am getting error.

Code:

function 2: Fetch NIFTY options chain data (update `instrument_key` before running)
function fetchUpstoxNiftyOptions() {
    var expiryDate = "2025-03-13"; // Update with the correct expiry date

    var instrumentKey = "NSE_OPT|NIFTY|2025-03-13"; 

    var url = "https://api.upstox.com/v2/option/chain?instrument_key=" + encodeURIComponent(instrumentKey) + "&expiry_date=" + expiryDate;

    var options = {
        "method": "GET",
        "headers": {
            "Authorization": "Bearer 1ABCDXYZ",
            "Accept": "application/json"
        },
        "muteHttpExceptions": true
    };

Error:

Hi @Arvind_47935823,

The instrument you are using is invalid. Please use a valid instrument key, such as NSE_INDEX|Nifty 50. You can check the instrument JSON file for the correct and updated instrument keys here: Instrument JSON.

Additionally, you may refer to the example codes for guidance: Example Codes.

Thanks!
