Webhooks

Description: When an invoice status changes (e.g. from "pending" to "paid"), the system sends a webhook to the URL you registered.

Payload:

{
  "invoiceId": "65e8b2f8c90e9e6b2a123456",
  "status": "paid",
  "updatedAt": "2025-04-09T12:15:00.000Z"
}

Recommendations:

  • Ensure your webhook endpoint responds with HTTP 200.

  • On failure, the system retries up to 3 times at 5‑minute intervals.
