# Create a Binary Category

You can use the `BinaryCatCreate` action to create binary categories. For details on this action, refer to the IDOL Server Reference. For example:

    http://12.3.4.56:9020/action=BinaryCatCreate&Name=spam_binarycat

This action uses port `9020` to instruct the IDOL Category component, which is located on a machine with the IP address `12.3.4.56`, to create a new binary category named `spam_binarycat`.
