Updates your internal customer ID (CustomerReferenceId) for a subscription. You can use this endpoint to match a unique customer ID (CustomerReferenceId) from your system with the automatically generated Internal customer ID in the Cleverbridge platform when the customer initially purchases the subscription. This way, you'll be able to easily identify any future events related to a customer with multiple subscriptions.
Note: The CustomerReferenceId corresponds to the internalCustomer field name (JSON) in the notifications you receive for some events related to one-time or recurring purchases the customer makes.
