# AddApplicationVpcConfiguration
<a name="API_AddApplicationVpcConfiguration"></a>

Adds a Virtual Private Cloud (VPC) configuration to the application. Applications can use VPCs to store and access resources securely.

Note the following about VPC configurations for Managed Service for Apache Flink applications:
+ VPC configurations are not supported for SQL applications.
+ When a VPC is added to a Managed Service for Apache Flink application, the application can no longer be accessed from the Internet directly. To enable Internet access to the application, add an Internet gateway to your VPC.

## Request Syntax

```
{
   "ApplicationName": "string",
   "ConditionalToken": "string",
   "CurrentApplicationVersionId": number,
   "VpcConfiguration": { 
      "SecurityGroupIds": [ "string" ],
      "SubnetIds": [ "string" ]
   }
}
```

## Request Parameters
<a name="API_AddApplicationVpcConfiguration_RequestParameters"></a>

The request accepts the following data in JSON format.

 ** [ApplicationName](#API_AddApplicationVpcConfiguration_RequestSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-request-ApplicationName"></a>
The name of an existing application.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 128.  
Pattern: `[a-zA-Z0-9_.-]+`   
Required: Yes

 ** [ConditionalToken](#API_AddApplicationVpcConfiguration_RequestSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-request-ConditionalToken"></a>
A value you use to implement strong concurrency for application updates. You must provide the `ApplicationVersionID` or the `ConditionalToken`. You get the application's current `ConditionalToken` using [DescribeApplication](API_DescribeApplication.md). For better concurrency support, use the `ConditionalToken` parameter instead of `CurrentApplicationVersionId`.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 512.  
Pattern: `[a-zA-Z0-9-_+/=]+`   
Required: No

 ** [CurrentApplicationVersionId](#API_AddApplicationVpcConfiguration_RequestSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-request-CurrentApplicationVersionId"></a>
The version of the application to which you want to add the VPC configuration. You must provide the `CurrentApplicationVersionId` or the `ConditionalToken`. You can use the [DescribeApplication](API_DescribeApplication.md) operation to get the current application version. If the version specified is not the current version, the `ConcurrentModificationException` is returned. For better concurrency support, use the `ConditionalToken` parameter instead of `CurrentApplicationVersionId`.  
Type: Long  
Valid Range: Minimum value of 1. Maximum value of 999999999.  
Required: No

 ** [VpcConfiguration](#API_AddApplicationVpcConfiguration_RequestSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-request-VpcConfiguration"></a>
Description of the VPC to add to the application.  
Type: [VpcConfiguration](API_VpcConfiguration.md) object  
Required: Yes

## Response Syntax

```
{
   "ApplicationARN": "string",
   "ApplicationVersionId": number,
   "OperationId": "string",
   "VpcConfigurationDescription": { 
      "SecurityGroupIds": [ "string" ],
      "SubnetIds": [ "string" ],

## Response Elements
<a name="API_AddApplicationVpcConfiguration_ResponseElements"></a>

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

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

 ** [ApplicationARN](#API_AddApplicationVpcConfiguration_ResponseSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-response-ApplicationARN"></a>
The ARN of the application.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 2048.  
Pattern: `arn:.*` 

 ** [ApplicationVersionId](#API_AddApplicationVpcConfiguration_ResponseSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-response-ApplicationVersionId"></a>
Provides the current application version. Managed Service for Apache Flink updates the ApplicationVersionId each time you update the application.  
Type: Long  
Valid Range: Minimum value of 1. Maximum value of 999999999.

 ** [OperationId](#API_AddApplicationVpcConfiguration_ResponseSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-response-OperationId"></a>
The operation ID that can be used to track the request.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.

 ** [VpcConfigurationDescription](#API_AddApplicationVpcConfiguration_ResponseSyntax) **   <a name="APIReference-AddApplicationVpcConfiguration-response-VpcConfigurationDescription"></a>
The parameters of the new VPC configuration.  
Type: [VpcConfigurationDescription](API_VpcConfigurationDescription.md) object

## Errors
<a name="API_AddApplicationVpcConfiguration_Errors"></a>
