# Contact processing

Contact processing offers an extension point for responding to the create or updating of a contact. Each time a contact is changed or updated, an event is queued up for processing along with the type of modification that was made. You can create a [contact processor](https://doc.sitecore.com/xp/en/developers/105/sitecore-experience-platform/create-a-contact-processor.html "Create a contact processor") to respond to these events.

> [!note]
> Contact processing is disabled by default. See [Enable contact processing](https://doc.sitecore.com/xp/en/developers/105/sitecore-experience-platform/enable-contact-processing.html "Enable contact processing").
