# Creating a new Transport.

### File location
All transports are located in `LibreNMS\Alert\Transport` and the files are named after the Transport name. I.e 
`Discord.php` for Discord.
 
### Transport structure.
The following functions are required for a new transport to pass the unit tests:

`deliverAlert()` - This is function called within alerts to invoke the transport. Here you should do any post processing 
of the transport config to get it ready for use.

`contact$Transport()` - This is named after the transport so for Discord it would be `contactDiscord()`. This is what 
 actually interacts with the 3rd party API, invokes the mail command or whatever you want your alert to do.
 
`configTemplate()` - This is used to define the form that will accept the transport config in the webui and then what 
data should be validated and how. Validation is done using [Laravel validation](https://laravel.com/docs/5.7/validation)

The following function is __not__ required for new Transports and is for legacy reasons only. `deliverAlertOld()`.

### Documentation
Please don't forget to update the [Transport](Transports.md) file to include details of your new transport.

A table should be provided to indicate the form values that we ask for and examples. I.e:

```
**Example:**
Config | Example
------ | -------
