# Send alerts with POST requests

BGPalerter can send alerts by means of POST requests to a provided URL.
This can be done by configuring the module reportHTTP. Read [here](configuration.md#reporthttp) to understand how.

For configuring reportHTTP, essentially you need to specify two things: 
* The URL
* A template of the POST request.

If you are using [user groups](usergroups.md), you can specify a URL for every user group. This can be done inside `hooks`, a dictionary containing API URLs grouped by user group (key: group, value: URL).
The default user group is mandatory.  
Example:
```yaml
      hooks:
        default: https://MY_WEB_HOOK/
        noc: https://MY_WEB_HOOK_FOR_THE_NOC_GROUP
```

You can also specify a template for each type of alert (channel). More information about templates is available [here](context.md).
Example:
```yaml
      isTemplateJSON: true
      templates:
        default: '{"message": "${summary}", "color": "blue"}'
        visibility: '{"message": "${summary}", "color": "orange"}'
```

Templates are expressed as strings. If the parameter `isTemplateJSON` is set to true, the string will be converted to JSON before to be posted.

What follows is a list of examples showing how to adapt this module to some well-known applications.


## Mattermost

Mattermost is an open source messaging platform.

```yaml

                "fields": [ 
                      {"title": "Event type:", "value": "${type}", "short": "true"},
                      {"title": "First event:", "value": "${earliest} UTC", "short": "true"},
                      {"title": "Last event:", "value": "${latest} UTC", "short": "true"}
                ], 
                "text": "${channel}: ${summary}", "color": "#ffffff"
              }
          ]}'
      isTemplateJSON: true
      headers:
      showPaths: 0 # Amount of AS_PATHs to report in the alert
      hooks:
        default: WEBHOOK_URL
```
