# ListPackageVersionDependencies
<a name="API_ListPackageVersionDependencies"></a>

 Returns the direct dependencies for a package version. The dependencies are returned as [PackageDependency](https://docs.aws.amazon.com/codeartifact/latest/APIReference/API_PackageDependency.html) objects. CodeArtifact extracts the dependencies for a package version from the metadata file for the package format (for example, the `package.json` file for npm packages and the `pom.xml` file for Maven). Any package version dependencies that are not listed in the configuration file are not returned.
