# MessageTriggerType

Which kind of run's changes a message trigger listens to. Use its `eventFilter` to fire only on, for example, a run that finished.

**Kind:** a string enum, used in requests and responses.

## Values

| Value | Description |
|---|---|
| `"AppProcessUpdated"` | An app run changed. |
| `"InteractionProcessUpdated"` | An interaction run changed. |
| `"CapsuleProcessUpdated"` | A capsule run changed. |

New values can appear, so treat one you don't know as "something else", not as an error.
