Overview

Webhooks would notify a future authorized consumer that a business event occurred. An event notification is not an instruction to approve an expense or execute a payment.

Key concepts

Separate event identity, resource identity and delivery attempt identity. Consumers should handle duplicate and out-of-order notifications.

Implementation considerations

No webhook is transmitted or subscribed from this website. Delivery guarantees and event availability remain proposed.

Illustrative data model

This local fixture shows a possible representation for the concepts above. It is not an endpoint response, production configuration or a claim that the described capability is implemented.

{
  "reference_only": true,
  "topic": "Webhooks Overview",
  "event_id": "event_example_123",
  "event_type": "expense.updated",
  "resource_id": "resource_example_123",
  "occurred_at": "2026-01-15T12:00:00Z"
}

Design review checklist

• Document which organization owns the webhooks overview representation and which actor may view or change it.
• Test the boundaries of event id, event type, resource id, occurred at using synthetic values, including missing or inconsistent references.
• Before future implementation, obtain an approved contract and review failure behavior. This documentation does not authorize production activation.
