**New features**

## Dispute case transition webhooks

Marqeta has created webhook events for dispute case transitions, eliminating the need for continuous API polling and enabling real-time notifications for dispute case updates.

You can now subscribe to `casetransition.*` events to receive instant notifications when dispute cases change status. The following event types are available under `casetransition.*` events:

| Event type | Definition |
| - | - |
| `open` | Case created |
| `open_with_action_required` | Action required |
| `ready` | Ready for chargeback submission |
| `chargeback.initiated` | Chargeback submitted |
| `pending_close` | Temporary state before the case closes |
| `closed` | Case closed |
