# GetAssociatedPackageGroup
<a name="API_GetAssociatedPackageGroup"></a>

Returns the most closely associated package group to the specified package. This API does not require that the package exist in any repository in the domain. As such, `GetAssociatedPackageGroup` can be used to see which package group's origin configuration applies to a package before that package is in a repository. This can be helpful to check if public packages are blocked without ingesting them.

For information package group association and matching, see [Package group definition syntax and matching behavior](https://docs.aws.amazon.com/codeartifact/latest/ug/package-group-definition-syntax-matching-behavior.html) in the *CodeArtifact User Guide*.

 The name of the domain that contains the package from which to get the associated package group.   
Length Constraints: Minimum length of 2. Maximum length of 50.  
Pattern: `[a-z][a-z0-9\-]{0,48}[a-z0-9]`   
Required: Yes

 ** [domainOwner](#API_GetAssociatedPackageGroup_RequestSyntax) **   <a name="codeartifact-GetAssociatedPackageGroup-request-uri-domainOwner"></a>
 The 12-digit account number of the AWS account that owns the domain. It does not include dashes or spaces.   
Length Constraints: Fixed length of 12.  
Pattern: `[0-9]{12}` 

 ** [format](#API_GetAssociatedPackageGroup_RequestSyntax) **   <a name="codeartifact-GetAssociatedPackageGroup-request-uri-format"></a>
 The format of the package from which to get the associated package group.   
Valid Values: `npm | pypi | maven | nuget | generic | ruby | swift | cargo`

 ** [namespace](#API_GetAssociatedPackageGroup_RequestSyntax) **   <a name="codeartifact-GetAssociatedPackageGroup-request-uri-namespace"></a>
The namespace of the package from which to get the associated package group. The package component that specifies its namespace depends on its type. For example:
