# tick

When set to `true`, the component will receive signals in regular intervals from the engine. The `tick()` Component Virtual method will be called in those intervals (see [Component Behaviour](https://docs.appmixer.com/building-connectors/behaviour)). This is especially useful for trigger-type of components that need to poll a certain API for changes. The polling interval can be set by the `COMPONENT_POLLING_INTERVAL` environment variable (for custom on-prem installations only). The default is 60000 (ms), i.e. 1 minute.
