Automatically Create Stripe Customer ID's

The 'Create Customer ID' field is a yes/no field that tells Stripe whether or not you want to automatically create a new Customer ID. If set to 'yes', a new Customer ID will automatically be created in every Checkout Session.

Please note that this will only apply when you are in 'payment' mode; i.e. when the Checkout Session involves one-off sales only (no subscription item).

A Stripe Customer ID is automatically created during every Checkout Session where a subscription product is sold.
