# Apply License (APYLIC)

To apply a permanent or temporary license key, you will use the included command APYLIC. Your license key will typically be supplied via email in a command string:

`APYLIC LICKEY(6E2222898982C8F1380F4DF08A23922C) PRODUCT(RXS)`

Or, you can copy and paste the received key into the command:

![Apply License (APYLIC)](https://isupport.katointegrations.com/rxs/3.3/apylic/apylic.png "Apply License (APYLIC)")

In either case after running the APYLIC command, you should receive a message that says **License applied successfully**

If you don't receive that message or receive an error message, please contact us at <a href="mailto:isupport@katointegrations.com">isupport@katointegrations.com</a>.
