Stripe testing subscription Lumen 5.1 - stripe-payments

Question

Im running Stripe in test mode.
I've created a Yearly billing plan for 100GBP amount, with a 7 days trial ( directly onto Stripe dashboard. )
However, to test the webhooks i've hardcoded the trial_end:
$trialEnd = new DateTime();
$trialEnd->setTimestamp(time()+120);
$user = Users::find($this->user()['user_id']);
$user->subscription($stripe_plan['stripe_plan'])->trialFor($trialEnd)->create($data['stripeToken'], [
'email' => $this->user()['email']
]);
$user->save();
Basically all goes well, but into stripe dashboard the first invoice for 0 GBP is shown, and after one minute i get the Subscription will end in a minute event. After all, the subscription become Active ( from Trialing ) state.
All the webhooks and even the first subscription add reponse i get the trial ends period instead subscription ends.
How can i get the subscription_ends_at timestamp ?
All webhook requests are having the following timestamps:
{
"id": "evt_18baRrIzJLF7fe6PMDPYD0NM",
"object": "event",
"api_version": "2016-07-06",
"created": 1469558315,
"data": {
"object": {
"id": "sub_8tNBbqy0AmSk8p",
"object": "subscription",
"application_fee_percent": null,
"cancel_at_period_end": false,
"canceled_at": null,
"created": 1469558268,
"current_period_end": 1469558384,
"current_period_start": 1469558268,
"customer": "cus_8tNB1tWYw3Jw7L",
"discount": null,
"ended_at": null,
"livemode": false,
"metadata": {
},
"plan": {
"id": "yearly_200",
"object": "plan",
"amount": 20000,
"created": 1469545724,
"currency": "gbp",
"interval": "year",
"interval_count": 1,
"livemode": false,
"metadata": {
},
"name": "Full Club Membership - Pay Anually",
"statement_descriptor": "FULL MEMBERSHIP",
"trial_period_days": 7
},
"quantity": 1,
"start": 1469558268,
"status": "trialing",
"tax_percent": null,
"trial_end": 1469558384,
"trial_start": 1469558268
}
},
"livemode": false,
"pending_webhooks": 1,
"request": null,
"type": "customer.subscription.trial_will_end"
}
So if you look at trial_start and trial_end is same with current_period_start and current_period_end.
I've though initially that if this is the current period.. fine, but after trial expires the current period shouldn't be trials one.
There is any method to take the subscription_ends_at field from Stripe api ? And also, after the trial period ends, shouldn't send a invoice with the real amount ?
Also, i created a subscription plan with no trial period. That plan after a client subscribed, i get the correct timestamps.
Thanks in advance!

Answer 1

It looks like you figured it out. Basically, the delay comes from the fact that when the timestamp passes for your trial expiration, your request to create a new Invoice on that billing cycle gets added to a queue. Typically the queue will create the new invoice ~immediately, but it can sometimes go several minutes before triggering.
The first Invoice will always have timestamps for the current_period_* that map to the trial_period_* ones. Whereas, the second Invoice (that shows up with the invoice.created-event) will have the accurate timestamps for the billing period.

Answer 2

Oh, now i understand .. i will explain maybe will help someone :D.
Basically if a subscription got a trial period when you subscribe you will get a invoice for 0. Then, even if you set the trial to expire in 2 minutes with the request , the first payment will occur in about 10 minutes :D ( with that payment (if you set a webhook url) you will get a "type": "customer.subscription.updated" event who will contain all desired informations. At that time you can update your subscription_ends_at .
I didn't wait 10 minutes to see if the new invoice will be triggered.. and created -> removed -> recreated -> removed and so on for 4 hours with different tests.
