# ListNetworkConnectorVersions
<a name="API_ListNetworkConnectorVersions"></a>

Returns a paginated list of the versions of a network connector. Each configuration update creates a new immutable version; this operation lists those versions for the connector you specify. You can optionally filter results by version state. Use the `Marker` parameter from a previous response to retrieve the next page of results.

Each item in the response includes the version-qualified ARN, version number, current state, and last modified timestamp for that version. To retrieve the current (latest) configuration of the connector, use `GetNetworkConnector`; to inspect a specific version, call `GetNetworkConnector` with a version-qualified identifier.

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

```
GET /2026-04-04/network-connectors/{{Identifier}}/versions?Marker={{Marker}}&MaxItems={{MaxItems}}&State={{State}} HTTP/1.1
```

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

The request uses the following URI parameters.

 ** [Identifier](#API_ListNetworkConnectorVersions_RequestSyntax) **   <a name="lambdacore-ListNetworkConnectorVersions-request-uri-Identifier"></a>
The identifier of the network connector whose versions you want to list. You can specify the connector ID, name, or full ARN. Specify an unqualified identifier — this operation lists all versions of the connector, not a specific version.  
Length Constraints: Minimum length of 1. Maximum length of 140.  
Required: Yes

 ** [Marker](#API_ListNetworkConnectorVersions_RequestSyntax) **   <a name="lambdacore-ListNetworkConnectorVersions-request-uri-Marker"></a>
The pagination token from a previous `ListNetworkConnectorVersions` response. Use this value to retrieve the next page of results.

 ** [MaxItems](#API_ListNetworkConnectorVersions_RequestSyntax) **   <a name="lambdacore-ListNetworkConnectorVersions-request-uri-MaxItems"></a>
The maximum number of versions to return per page. Valid range: 1 to 100.  
Valid Range: Minimum value of 1. Maximum value of 100.

 ** [State](#API_ListNetworkConnectorVersions_RequestSyntax) **   <a name="lambdacore-ListNetworkConnectorVersions-request-uri-State"></a>
Optional filter to return only versions in the specified state (for example, `ACTIVE` or `FAILED`).  
Valid Values: `PENDING | ACTIVE | INACTIVE | FAILED | DELETING | DELETE_FAILED`
