A service resource represents a service inside MaxScale. A service is a
collection of network listeners, filters, a router and a set of backend servers.
## Resource Operations

all whitespace replaced with hyphens. The service names are case-insensitive.
```

### Get service listeners
Get the listeners of a service. The _:name_ in the URI must be a valid service
name with all whitespace replaced with hyphens. The service names are
case-insensitive.
```
GET /v1/services/:name/listeners
```
#### Response
`Status: 200 OK`
```javascript
{
"links": {
"self": "http://localhost:8989/v1/services/Read-Connection-Router/listeners"
},
"data": [
{
"attributes": {
"parameters": {
"port": 4008,
"protocol": "MySQLClient",
"authenticator": "MySQLAuth"
}
},
"id": "Read-Connection-Listener",
"type": "listeners"
}
]
}
```
### Create a new listener
```
POST /v1/services/:name/listeners
```
Create a new listener for a service by defining the resource. The _:name_ in the
URI must map to a service name with all whitespace replaced with hyphens. The
posted object must define the _data.id_ field with the name of the server and
the _data.attributes.parameters.port_ field with the port where the listener
will listen on. The following is the minimal required JSON object for defining a
new listener.
```javascript
{
"data": {
"id": "my-listener",
"type": "listeners",
"attributes": {
"parameters": {
"port": 3306
}
}
}
}
```
The following table contains all values that can be given in the _parameters_
object.
|Parameter | Description |
|-----------------------|---------------------------------------------------|
|port | Port to listen on |
|address | Interface to listen on |
|authenticator | Authenticator module |
|authenticator_options | Options for the authenticator |
|ssl_key | Path to SSL key |
|ssl_cert | Path to SSL certificate |
|ssl_ca_cert | Path to SSL CA certificate |
|ssl_version | The SSL version to use [TLSv1.2|TLSv1.1|TLSv1.0] |
|ssl_cert_verify_depth | Certificate verification depth |
### Destroy a listener
```
DELETE /v1/services/:service/listeners/:name
```
In the URI , the _:name_ must map to a listener and the _:service_ must map to a
service. Both names must have all whitespace replaced with hyphens.
#### Response
OK:
```
Status: 204 No Content
```
Listener not found:
```
Status: 404 Not Found
```
Listener cannot be deleted:
```
Status: 403 Forbidden
```
### Update a service
The _:name_ in the URI must map to a service name and the request body must be a
valid JSON Patch document which is applied to the resource.
```
PATCH /v1/services/:name
```
The following standard service parameters can be modified.
- [user](../Getting-Started/Configuration-Guide.md#user)
