This is applicable only to users of REST API
When sending requests for InstrumentIdentifiers which contain special characters in their names – for example L&T, M&M, NIFTY 50 (there is a white space between NIFTY and 50), you will need to use URL Encoding as explained Here.
Some examples are as below :
| Identifier Name | InstrumentIdentifier to be sent in API Request |
| L&T | L%26T |
| M&M | M%26M |
| NIFTY 50 | NIFTY%2050 |
| NIFTY BANK | NIFTY%20BANK |
| MCDOWELL-N | MCDOWELL%2DN |
