If you receive the error "Reason code: API 454 - Invalid data", this is likely to be caused by the billable item in your settings.
​
A "Billable item" is usually attached to your appointment type, the billable item code reflects the HealthPoint item codes.

A "Billable item" must match a HealthPoint item code as this is what we use when making a private health insurance claim.
​
​Note: A Billable item must only be digits.
