Getting {"success":false,"message":"Invalid API Key","errorCode":"AG8004","data":""} on both getCandleData and getLtpData. loginByPassword and getProfile both succeed with the same API key. I've verified my request headers match the official smartapi-python SDK exactly (Content-Type, X-UserType, X-SourceID, X-ClientLocalIP, X-ClientPublicIP, X-MACAddress, X-PrivateKey, Authorization). My dashboard only shows one API Type ("Trading") with no option to add Historical Data/Market Feed separately. Is there a separate activation step needed for historical/quote data access, or something else I'm missing?
