instrument_token vs exchange_token vs tradingsymbol vs name

anwoy

Hi,
My question is regarding the change of the symbol names. Since sometimes trading symbols change, how is that reflected in the instruments data? do the instrument_token etc remain the same? Examples of changes in NSE in the past:
NIITTECH was changed to COFORGE,
ESSELPACK was changed to EPL,
IBVENTURES was changed to DHANI,
STRTECH was changed to STLTECH,
IBULISL was changed to YAARI,
INFRATEL was changed to INDUSTOWER,
ADANIGAS was changed to ATGL,
JUBILANT was changed to JUBLPHARMA,
ORIENTREF was changed to RHIM,
CADILAHC was changed to ZYDUSLIFE,
MOTHERSUMI was changed to MOTHERSON,
WABCOINDIA was changed to ZFCVINDIA

Thanks in Advance

do the instrument_token etc remain the same?

No, it mostly changes.

so is there a way to keep track of these changes from within the kite API?

You need to download instruments master dump everyday. You will have to compare today and previous day's dump.
