How to determine ZohoCreator organization ID

How to determine ZohoCreator organization ID

I am trying to setup an API to interface with my ZohoCreator app by following the self-client credential flow here https://www.zoho.com/accounts/protocol/oauth/self-client/client-credentials-flow.html

However, it requires me to input my organization ID. Any idea how I can find my ZohoCreator organization ID?
