# Completing a next action for PaymentIntents created with one-off invoices

Invoices will automatically generate [PaymentIntents](https://stripe.com/docs/payments/payment-intents#one-time-payments) objects and will indicate when a next action is needed. `invoice.payment_action_required` will generate when a next action is needed such as requiring 3D Secure, and the `hosted_invoice_url` returned in that event contains a button for the customer to complete the payment.
## Additional Information
* There is no automatic redirect with invoices. You will need to either have Stripe send the notification for you, or provide the link to your customer for completion once the invoice is generated.
  * Notification settings can be found under the [email and notifications settings section for Billing](https://dashboard.stripe.com/account/billing/automatic).
