# Set Controller Endpoint (LCC.set_api_url)

## Signature​

    LCC.set_api_url(url)

## Parameters​

- url
  String. HTTP base URL of the controller server (for example `http://192.168.1.100:46990`).

## Returns​

- none

## Notes​

> Stores the controller address for all subsequent API calls.
> When the script is not launched by the controller, you must invoke this before `LCC.connect()`.
> Calling it overwrites the previously saved address and refreshes the in-memory module settings.

## Example​

    LCC.set_api_url("http://192.168.1.100:46990")
    if not LCC.connect() then
        error("Unable to reach controller")
    end
