Hi
You can't increase that.

One option is create a first subscirption with 720 days trial

and before expiration in your integration, you extend the trial/create another phase if you are using Subscription Schedule

[rigid chasm]

Can you clear more?

You mean,

await stripe.subscriptionSchedules.create({
from_subscription: 'existingSubscriptionId',
start_date: 1680716828, // The date to execute
trial_end: 1680716828,
})

You create a first Subscription with 720 days trial.

After 720 days, just before trial ends, you update the Subscirption with the remaining trial days

[rigid chasm]

But how I know when the subscription ends,

I don't want to create cron job for checking,.

[rigid chasm]

The Stripe auto support feature to update trial end?

as you suggest Subscription Schedule

My purpose: First I have subscription with trial day 1 year.

You can set webhooks for that

[rigid chasm]

After that I want to extend subscription plus 2 year?

[fluid moon]

You can listen to this event customer.subscription.trial_will_end

https://stripe.com/docs/billing/subscriptions/webhooks#:~:text=is unpaused.-,customer.subscription.trial_will_end,-Sent three days

In your case, if you create a Subscription with 720 days trials, you'll be notified after 717 days (before 3 days)

and then you extend the Subscription trial

[rigid chasm]

oh that's good idea,

Happy to help!
