If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in XML format by the service.

 ** [OriginAccessControlConfig](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-OriginAccessControlConfig"></a>
Root level tag for the OriginAccessControlConfig parameters.  
Required: Yes

 ** [Description](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-Description"></a>
A description of the origin access control.  
Type: String

 ** [Name](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-Name"></a>
A name to identify the origin access control. You can specify up to 64 characters.  
Type: String

 ** [OriginAccessControlOriginType](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-OriginAccessControlOriginType"></a>
The type of origin that this origin access control is for.  
Type: String  
Valid Values: `s3 | mediastore | mediapackagev2 | lambda` 

 ** [SigningBehavior](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-SigningBehavior"></a>
Specifies which requests CloudFront signs (adds authentication information to). Specify `always` for the most common use case. For more information, see [origin access control advanced settings](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/private-content-restricting-access-to-s3.html#oac-advanced-settings) in the *Amazon CloudFront Developer Guide*.  
This field can have one of the following values:  
+  `always` – CloudFront signs all origin requests, overwriting the `Authorization` header from the viewer request if one exists.
+  `never` – CloudFront doesn't sign any origin requests. This value turns off origin access control for all origins in all distributions that use this origin access control.
+  `no-override` – If the viewer request doesn't contain the `Authorization` header, then CloudFront signs the origin request. If the viewer request contains the `Authorization` header, then CloudFront doesn't sign the origin request and instead passes along the `Authorization` header from the viewer request. **WARNING: To pass along the `Authorization` header from the viewer request, you *must* add the `Authorization` header to a [cache policy](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/controlling-the-cache-key.html) for all cache behaviors that use origins associated with this origin access control.** 
Type: String  
Valid Values: `never | always | no-override` 

 ** [SigningProtocol](#API_GetOriginAccessControlConfig_ResponseSyntax) **   <a name="cloudfront-GetOriginAccessControlConfig-response-SigningProtocol"></a>
The signing protocol of the origin access control, which determines how CloudFront signs (authenticates) requests. The only valid value is `sigv4`.  
Type: String  
Valid Values: `sigv4`
