for seamless subscription management.When a customer's free trial period concludes, Stripe emits a customer.subscription.updated
event. This event signifies a transition in the subscription's state, typically from trialing
to active
if a valid payment method is on file, or to another status such as canceled
if the subscription cannot proceed due to payment issues.
Tracking the customer.subscription.updated
event is crucial for maintaining an up-to-date understanding of your subscriptions. It allows you to automate processes such as activating services, sending notifications, and handling payment failures, thereby enhancing customer experience and operational efficiency.
The status
field indicates the current state of the subscription. Upon trial end, this field typically transitions as follows:
active
: The subscription has moved to a paid state.canceled
: The subscription has been terminated, possibly due to payment issues.paused
: The subscription is on hold pending further actions, such as adding a payment method.The previous_attributes
section provides a snapshot of the subscription's state before the event was triggered. Specifically, it indicates if the status changed from trialing
to another state:
"previous_attributes": {
"status": "trialing",
"trial_end": 1700000000
}
This information is vital for understanding the nature of the transition and for implementing conditional logic in your application.
The trial_end
field specifies the exact time the trial period concluded. Post-trial, this field is removed from the subscription object:
"trial_end": 1700000000
Monitoring this timestamp helps in correlating the event with the trial duration and in scheduling follow-up actions accordingly.
The billing_cycle_anchor
field marks the start of the new billing period. Its update indicates the commencement of regular billing post-trial:
"billing_cycle_anchor": 1700000000
The current_period_start
and current_period_end
fields reflect the new billing cycle's timeframe. These updates are essential for managing billing cycles and ensuring accurate invoicing:
"current_period_start": 1700000000,
"current_period_end": 1702592000
Following the customer.subscription.updated
event, Stripe typically sends either an invoice.payment_succeeded
or invoice.payment_failed
event. These subsequent events notify you of the payment outcome:
invoice.payment_succeeded
: Indicates successful billing, confirming the transition to an active subscription.invoice.payment_failed
: Signals payment issues, which may necessitate further actions like retrying the payment or notifying the customer.To effectively respond to the customer.subscription.updated
event, integrating a webhook handler is essential. Webhooks allow your application to receive real-time notifications about subscription changes, enabling automated responses to various scenarios.

When a payment succeeds after a trial ends, the invoice.payment_succeeded
event confirms the activation of the subscription. This allows you to finalize any setup required for the paid subscription.
If the payment fails, Stripe sends an invoice.payment_failed
event. You should implement logic to handle such scenarios, such as notifying the customer to update their payment method or retrying the payment.
In cases where no payment method is attached at the end of the trial, the subscription may transition to states like incomplete
or past_due
. It's crucial to monitor these states to prompt customers to provide valid payment information promptly.
Utilize the customer.subscription.trial_will_end
event to notify customers about the impending end of their trial. Sending reminders can improve conversion rates from trial to paid subscriptions.
Maintain detailed logs of all subscription events. This practice aids in debugging issues and provides a historical record of subscription changes for auditing purposes.
Implement automated communication strategies, such as sending emails upon subscription activation, payment failures, or cancellations. Clear communication enhances user experience and reduces confusion.
Regularly test your webhook endpoints using Stripe's testing tools. Ensuring that your handlers correctly process events prevents disruptions in subscription management.
