# Template data
Template data is passed on to [message templates]({{< relref "./_index.md" >}}) as well as sent as payload to webhook pushes.
Name | Type | Notes
------------------|----------|-----------------------------------------------------------------
Receiver | string | Name of the contact point that the notification is being sent to.
Status | string | `firing` if at least one alert is firing, otherwise `resolved`.
Alerts | Alert | List of alert objects that are included in this notification (see below).
GroupLabels | KeyValue | Labels these alerts were grouped by.
CommonLabels | KeyValue | Labels common to all the alerts included in this notification.
CommonAnnotations | KeyValue | Annotations common to all the alerts included in this notification.
ExternalURL | string | Back link to the Grafana that sent the notification. If using external Alertmanager, back link to this Alertmanager.
The `Alerts` type exposes functions for filtering alerts:
* `Alerts.Firing` returns a list of firing alerts.
* `Alerts.Resolved` returns a list of resolved alerts.

## KeyValue
`KeyValue` is a set of key/value string pairs that represent labels and annotations.
Here is an example containing two annotations:
```json
{
"summary": "alert summary",
"description": "alert description"
}
```
In addition to direct access of data (labels and annotations) stored as KeyValue, there are also methods for sorting, removing and transforming.
Name | Arguments | Returns | Notes
------------|-----------|-----------------------------------------|----------------
SortedPairs | | Sorted list of key & value string pairs |
Remove | []string | KeyValue | Returns a copy of the Key/Value map without the given keys.
Names | | []string | List of label names
Values | | []string | List of label values
## Functions
Some functions to transform values are also available, along with [default functions provided by Go templating](https://golang.org/pkg/text/template/#hdr-Functions).
