Invoices

Overview

Invoice webhooks notify your application about the lifecycle of invoices. Use these events to track billing activity, notify customers about payments, handle failed charges, and build automated billing workflows.

Use Cases

Notify customers when a new invoice is generated
Send payment confirmation emails on successful charges
Trigger dunning workflows when payments fail
Alert customers when payment action (e.g. 3D Secure) is required
Build dashboards to track billing metrics and revenue
Send advance notice to customers about upcoming invoices

Events

Event	Description
`invoice.created`	A new invoice was generated
`invoice.updated`	An invoice was updated (e.g. status change, payment applied)
`invoice.upcoming`	An invoice will be generated soon for an upcoming billing cycle
`invoice.payment_succeeded`	Payment was successfully collected for an invoice
`invoice.payment_failed`	Payment collection failed for an invoice
`invoice.payment_action_required`	Customer action is required to complete payment (e.g. 3D Secure authentication)

invoice.created

Triggered When

A subscription is created and its first invoice is generated
A subscription renews and a new billing cycle invoice is created

      "...": "Same structure as invoice.created"
    }
  }
}

      "...": "Same structure as invoice.created"
    },
    "previous_attributes": {
      "status": "open"
    }
  }
}

Note: The previous_attributes object is automatically detected from model changes. If no publishable fields changed during the failed payment attempt, previous_attributes will be an empty object.

The payment gateway returns a requires_action status

Payload

{
  "type": "invoice.payment_action_required",

Invoice Lifecycle

The typical lifecycle of an invoice follows one of these sequences:

Successful payment (charge automatically):

invoice.created - Invoice generated
invoice.payment_succeeded - Payment collected
invoice.updated - Status changed to paid

Successful payment (send invoice):

invoice.upcoming - Advance notice of upcoming invoice
invoice.created - Invoice generated and sent
invoice.payment_succeeded - Customer pays the invoice
invoice.updated - Status changed to paid

Failed payment:

invoice.created - Invoice generated
invoice.payment_failed - Payment attempt failed
invoice.updated - Status may change (e.g. to uncollectible)

Payment requiring action (3D Secure):

invoice.created - Invoice generated
invoice.payment_action_required - Customer must complete authentication
invoice.payment_succeeded - Payment completed after authentication
invoice.updated - Status changed to paid
