# Token Selection

Clients can manage more than one token via the TokenOS API. To select which token you’d like to manage, use the special header `X-Token-ID` with the value set to the token’s symbol (i.e. `-H “X-Token-ID: SYMBOL”`. Note that you should not include the dollar sign).

Providing a token ID that you do not have permission to access will yield a `403` error.
