= Configure Integrations

Runtime properties associated to an integration can be configured using the `--property` flag when running the integration. If the property is a *build time property* (ie, certain `Quarkus` configuration), then, you can use xref:configuration/build-time-properties.adoc[`--build-property`] instead.

The property value can be used inside Camel K integrations using the *property placeholder* mechanism.

The syntax for properties has the form `{{my.property}}`, for example:

[source,groovy]
.props.groovy
----
from('timer:props?period=1000')
    .log('{{my.message}}')
----

In order to give a value to the `my.message` property you can pass it using the command line:

```
kamel run --property my.message="Hello World" examples/props.js
```

For more details and advanced use cases, see the xref:configuration/runtime-properties.adoc[runtime properties] section.
