Hi! Let me help you with this.

You should use Subscription Schedules.

start_date is not something you can set when creating a regular Subscription.

so, what should we do then?

[hazy temple]

You can follow this guide to start a subscription in the future with Subscription Schedules:
https://stripe.com/docs/billing/subscriptions/subscription-schedules/use-cases#start-subscription-future

[tame apex]

and we should pass the parameter in unix?

or can we use date?

and one more question: is end_behavior optional? what does it do?

[hazy temple]

It's a Unix time, in seconds (not milliseconds).

end_behavior: 'release' says that after the schedule have done it's job - in your case - starts the subscription with delay, it will just turn into a regular schedule.

'release' is the default so you can skip it. However, it's also good to be explicit.
