# CreateInvalidation
<a name="API_CreateInvalidation"></a>

Create a new invalidation. For more information, see [Invalidating files](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Invalidation.html) in the *Amazon CloudFront Developer Guide*.

## Request Syntax
<a name="API_CreateInvalidation_RequestSyntax"></a>

```
POST /2020-05-31/distribution/DistributionId/invalidation HTTP/1.1
<?xml version="1.0" encoding="UTF-8"?>
<InvalidationBatch xmlns="http://cloudfront.amazonaws.com/doc/2020-05-31/">
   <CallerReference>string</CallerReference>
   <Paths>
      <Items>
         <Path>string</Path>
      </Items>
      <Quantity>integer</Quantity>

</InvalidationBatch>
```

## URI Request Parameters
<a name="API_CreateInvalidation_RequestParameters"></a>

The request does not use any URI parameters.

## Request Body
<a name="API_CreateInvalidation_RequestBody"></a>

The request accepts the following data in XML format.

 ** [InvalidationBatch](#API_CreateInvalidation_RequestSyntax) **   <a name="cloudfront-CreateInvalidation-request-InvalidationBatch"></a>
Root level tag for the InvalidationBatch parameters.  
Required: Yes

 ** [CallerReference](#API_CreateInvalidation_RequestSyntax) **   <a name="cloudfront-CreateInvalidation-request-CallerReference"></a>
A value that you specify to uniquely identify an invalidation request. CloudFront uses the value to prevent you from accidentally resubmitting an identical request. Whenever you create a new invalidation request, you must specify a new value for `CallerReference` and change other values in the request as applicable. One way to ensure that the value of `CallerReference` is unique is to use a `timestamp`, for example, `20120301090000`.  
If you make a second invalidation request with the same value for `CallerReference`, and if the rest of the request is the same, CloudFront doesn't create a new invalidation request. Instead, CloudFront returns information about the invalidation request that you previously created with the same `CallerReference`.  
If `CallerReference` is a value you already sent in a previous invalidation batch request but the content of any `Path` is different from the original request, CloudFront returns an `InvalidationBatchAlreadyExists` error.  
Type: String  
Required: Yes

 ** [Paths](#API_CreateInvalidation_RequestSyntax) **   <a name="cloudfront-CreateInvalidation-request-Paths"></a>
A complex type that contains information about the objects that you want to invalidate. For more information, see [Specifying the Objects to Invalidate](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Invalidation.html#invalidation-specifying-objects) in the *Amazon CloudFront Developer Guide*.  
Type: [Paths](API_Paths.md) object  
Required: Yes
