Cancel a subscription order through ClickFunnels' own cancel path (the same path the
in-app "Cancel subscription" flow uses) so the cancelation actually propagates to the
payment processor (Payments AI/Rebilly or Stripe). A direct PATCH /orders/{id} write
of service_status: canceled is a no-op for processor-managed orders, which is why this
action exists.

Only Payments AI and Stripe subscription orders can be canceled. Calling this on a
one-time order or an external subscription returns a 422. Please refer to our Orders
Overview guide for more information
about the different types of orders and payment processors.

See Cancel a subscription in the Orders Skill for the
request body, the accepted cancel_reason values per processor, and a worked example
that confirms the scheduled churn.
