# Quote Messages

Messages that represent a change or an action performed on a Quote Request, Staged Quote, or Quote.

Messages are available in a variety of [Message Types](/api/projects/messages.md#message-types) specific to a resource. Common fields across all Message Types are represented by a base resource, [Message](/urn?urn=ctp%3Aapi%3Atype%3AMessage).

You can access Messages either by querying the [Messages API](/api/projects/messages.md), or by subscribing to them with a [Subscription](/api/projects/subscriptions.md). To query Messages using the API, you must [enable the feature](/api/projects/messages.md#enable-querying-messages-via-the-api) first.
