#Stripe API Test / Create subscription schedule  /  only once iteration / and immediately cancel subscription / invoice and pay /   Ruby code with stripe gem

# If you set billing cycle anchor to subscription over  natural cycle of subscription then see below error


```
Stripe::InvalidRequestError: billing_cycle_anchor cannot be later than next natural billing date (<timestamp>) for plan
```

# Let's use Subscription schedule

billing cycle anchor is not for schedule
Subscription schedule is for schedule Subscription!

# For example

you can specify 100 days after as subscription start over subscription cycle.
you can specify only one cycle  subscription by "iteration" property. and subscription will be cancel first subscription created.
