The status of an event type determines how and if you can use the event type in Event Streams. Event type status can be: available, deprecated, restricted, or discontinued. In most cases, an event type is deprecated to give notice to users before before being restricted or discontinued.
Most event types have a status of available. If an event type is deprecated, restricted, or discontinued, then you'll get a warning in the Twilio Console.
You should replace a deprecated or restricted event type with the recommended alternative before the event type is discontinued.

The following table shows what you can do with an event type based on the event type status.
| Event type status | Usage | Receive events in existing subscriptions | Create new subscriptions to the event type | Add the event type to existing subscriptions |
|---|---|---|---|---|
| Available | Available event types are ready to use. | ✅ | ✅ | ✅ |
| Deprecated | You can still use deprecated event types, but you should start looking for alternatives. | ✅ | ✅ | ✅ |
| Restricted | You should immediately replace restricted event types with alternatives. | ✅ | ❌ | ❌ |
| Discontinued | You may not receive events for discontinued event types. If a subscription uses multiple event types, then the subscription will still receive events for event types that aren't discontinued. | ❌ | ❌ | ❌ |
