Hi,
I confirm that I am passing the header correctly in the request. This is not the only API I am using couple other API's [get positions, candledata etc] as well and they are working fine. Also, it worked all fine till now yesterday as well it worked fine once so that means the issue is not with headers. Possible to have a google meet or some kind of connect? talking like this back and forth is not helping at all. Hope you understand.
