| Method | URI |
| --- | --- |
| GET | /vloadbalancer/v2/createLoadBalancerListener |

### Request headers

For information about the headers common to all Load Balancer APIs, see [Load Balancer request headers](/docs/en/networking-vloadbalancer#%EC%9A%94%EC%B2%AD%ED%97%A4%EB%8D%94).

### Request query parameters

You can use the following query parameters with your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `regionCode` | String | Optional | Region code for the load balancer instance whose listener you want to create - First Region of the getRegionList search result (default) - See [getRegionList](/docs/en/compute-vserver-server-common-getregionlist) |
| `loadBalancerInstanceNo` | String | Required | Number of the load balancer instance - See [getLoadBalancerInstanceList](/docs/en/networking-vloadbalancer-loadbalancer-getloadbalancerinstancelist) |
| `protocolTypeCode` | String | Required | Protocol type of load balancer listener - `HTTP` \| `HTTPS` \| `TCP` \| `UDP` \| `TLS` - Type of load balancer limits the values you can select - Application Load Balancer: `HTTP` \| `HTTPS` - Network Load Balancer: `TCP` \| `UDP` - Network Proxy Load Balancer: `TCP` \| `TLS` - `UDP` protocol is only available in Singapore and Japan Regions |
| `port` | Integer | Required | Port of the listener - 1 - 65534 - It can't be duplicated with an existing registered listener port |
| `targetGroupNo` | String | Required | Target group number - See [getTargetGroupList](/docs/en/networking-vloadbalancer-targetgroup-gettargetgrouplist) - Selected target group is applied to the listener's default rule - Target groups already in use by another load balancer can't be used - Available target groups are limited by the type of load balancer and the protocol type of the target group - Network Load Balancer: `TCP` \| `UDP` - Application Load Balancer: `HTTP` \| `HTTPS` - Network Proxy Load Balancer: `PROXY_TCP` |
| `useHttp2` | Boolean | Optional | Whether to use the HTTP/2 protocol - `true` \| `false` (default) - It can be set if the listener's protocol type is `HTTPS` |
| `sslCertificateNo` | String | Conditional | SSL certificate number - See [getCertificateList](/docs/en/security-certificatemanager-getcertificatelist) - If the listener's protocol type is `HTTPS` or `TLS`, the SSL certificate must be set |
| `tlsMinVersionTypeCode` | String | Optional | TLS minimum supported version - `TLSV10` (default) \| `TLSV11` \| `TLSV12` - `TLSV10`: TLS 1.0 - `TLSV11`: TLS 1.1 - `TLSV12`: TLS 1.2 - It can be set if the listener's protocol type is `HTTPS` or `TLS` |
| `cipherSuiteList.N` | List[String] | Optional | List of encryption tools provided by the load balancer when negotiating encryption with the client - `TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA` \| `TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256` \| `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` \| `TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA` \| `TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384` \| `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384` \| `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA` \| `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256` \| `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` \| `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA` \| `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384` \| `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384` \| `TLS_RSA_WITH_AES_128_CBC_SHA` \| `TLS_RSA_WITH_AES_128_CBC_SHA256` \| `TLS_RSA_WITH_AES_128_GCM_SHA256` \| `TLS_RSA_WITH_AES_256_CBC_SHA` \| `TLS_RSA_WITH_AES_256_CBC_SHA256` \| `TLS_RSA_WITH_AES_256_GCM_SHA384` \| `TLS_DHE_RSA_WITH_AES_128_CBC_SHA` \| `TLS_DHE_RSA_WITH_AES_128_CBC_SHA256` \| `TLS_DHE_RSA_WITH_AES_256_CBC_SHA` \| `TLS_DHE_RSA_WITH_AES_256_CBC_SHA256` - Select All (default) - It can be set if the listener's protocol type is `HTTPS` or `TLS` |
| `responseFormatType` | String | Optional | Response result format - `xml` (default) \| `json` |
