If it is necessary to check and/or change the used API key for a Litmus Edge device, because for example the Key previously used has been deleted, the user can provide a new API Key through the **Litmus Edge & API Key** form.

## Change the API Key when Connected To One LE

To open the **Litmus Edge & API Key** form when the tool is set to** Connect To** *One LE*, a Target IP needs to be set.
To open the form press the **API key** button from the LitmusConfiguration Ribbon.

## Change the API Key when Connected To Multiple LE

To open the **Litmus Edge & API Key** form when the tool is set to** Connect To ***Multiple LE*, at least one Target Litmus Edge IP needs to be set.

You can verify the API Key in two ways.

## Check all API Keys automated

Press the **Refresh Sheet **button from the **LitmusConfiguration **ribbon to have the tool check for every **Target Limtus Edge IP** if it can connect to and request an API Key if necessary.

If the tool identifies for example that the API Key it has defined for a Litmus Edge causes a 401 error.

It will request that the user verifies the currently defiend API Key and provide a new valid API Key in case the current API Key is invalid.
