Instrument Key format

is there a specific format for Instrunment key or do we have to download the file locally everyday and use this in the system?

for example if i want to get candle data for SBI or IEX is the only way to find the corresponding number for the specific stock?

thank you in advance

The instrument key is composed using several methods to guarantee its uniqueness. The most effective approach for utilizing it would be to base your logic on the provided instruments file.
