# Checkout Webhooks

<Note>
  When a checkout is created on behalf of an entity (Checkout OBO), all webhook payloads include the `on_behalf_of` field (the entity ID) in the `data` object. This field is omitted when OBO is not used.
</Note>

## Payment\_Status-specific events:

These are the events created and triggered when the payment\_status of the checkout object changes.
