# Configuration

> Create and retrieve immutable configuration revisions for an integration in Cognite Data Fusion (CDF).

Configuration lets you manage versioned settings for an integration. Each change creates a new revision, so you have a history of what was active at a given time. Extractors fetch the active revision when they start and when they report in to CDF.

## What integration configuration is

Integration configuration is a revisioned document associated with an integration. Every time you push a new configuration, CDF stores it as a new revision rather than overwriting the previous one. This lets you audit configuration changes and know exactly which revision an extractor was running at any point in time.

## Managing configuration revisions

You create a new configuration revision when you want to change how an extractor behaves. You can list all revisions for an integration to review its configuration history, or retrieve a specific revision, the revision active at a given time, or the revision an extractor currently reports using.

<Info>
  Configuration revisions are immutable once created. To change behavior, create a new revision rather than editing an old one.

## Key operations

* **Create revision**: Push a new configuration revision for an integration.
* **List revisions**: Review the configuration history for an integration.
* **Retrieve**: Get a specific revision, or the revision active at a given time.

Versioned configuration ties together what an extractor is running with the task and error data it reports, so you can correlate behavior changes with configuration changes.
