# UpdateNetworkConnector
<a name="API_UpdateNetworkConnector"></a>

Updates the VPC configuration or operator role of an existing network connector. You can modify the subnet IDs, security group IDs, network protocol, or operator role. The connector must be in `ACTIVE` state to accept updates.

This operation is asynchronous. The connector remains in `ACTIVE` state during the update — existing workloads that reference this connector are not disrupted. Use `GetNetworkConnector` to monitor the `LastUpdateStatus` field, which transitions through `InProgress` to `Successful` or `Failed`. If the update fails, the `LastUpdateStatusReasonCode` field provides a specific error code for troubleshooting. This operation is idempotent when you provide a `ClientToken`.

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

```
PUT /2026-04-04/network-connectors/{{Identifier}} HTTP/1.1
Content-type: application/json

{
   "ClientToken": "{{string}}",
   "Configuration": { ... },
   "OperatorRole": "{{string}}"
}
```

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

The request uses the following URI parameters.

 ** [Identifier](#API_UpdateNetworkConnector_RequestSyntax) **   <a name="lambdacore-UpdateNetworkConnector-request-uri-Identifier"></a>
The identifier of the network connector to update. You can specify the connector ID, name, or full ARN.  
Length Constraints: Minimum length of 1. Maximum length of 140.  
Required: Yes

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

The request accepts the following data in JSON format.

 ** [ClientToken](#API_UpdateNetworkConnector_RequestSyntax) **   <a name="lambdacore-UpdateNetworkConnector-request-ClientToken"></a>
A unique, case-sensitive identifier to ensure idempotency of the update request.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Required: No

 ** [Configuration](#API_UpdateNetworkConnector_RequestSyntax) **   <a name="lambdacore-UpdateNetworkConnector-request-Configuration"></a>
The updated network configuration for the connector. Provide the full `VpcEgressConfiguration` including all subnet IDs and security group IDs — this replaces the existing configuration.  
Type: [NetworkConnectorConfiguration](API_NetworkConnectorConfiguration.md) object  
 **Note: **This object is a Union. Only one member of this object can be specified or returned.  
Required: No

 ** [OperatorRole](#API_UpdateNetworkConnector_RequestSyntax) **   <a name="lambdacore-UpdateNetworkConnector-request-OperatorRole"></a>
The updated ARN of the IAM role that Lambda assumes to manage ENIs. Use this to change the operator role without recreating the connector.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 10000.  
Pattern: `arn:(aws[a-zA-Z-]*)?:iam::\d{12}:role/?[a-zA-Z_0-9+=,.@\-_/]+`   
Required: No
