Message Template

Message Templates are the best way to structure and customize your messages and also very useful for compatiblity between different services.

Configure them by using the message.template attribute in you config.

These support Go Templates (See Templates) and work by templating the message attribute in the request's body.

Here is an example:

settings:
  message:
    template: |
      {{- $greeting := "Hello" -}}
      {{ $greeting }}, {{ @name }}!
      {{ if @age -}}
      You are {{ @age }} years old.
      {{- else -}}
      Age unknown.
      {{- end }}
      Your friends:
      {{- range @friends }}
      - {{ . }}
      {{- else }}
      You have no friends.
      {{- end }}
      Profile details:
      {{- range $key, $value := @profile }}
      - {{ $key }}: {{ $value }}
      {{- end }}
      {{ define "footer" -}}
      This is the footer for {{ @name }}.
      {{- end }}
      {{ template "footer" . -}}
      ------------------------------------
      Content-Type: {{ #Content_Type }}
      Redacted Auth Header: {{ #Authorization }}

info

Message Templates support Standard Golang Templating. Use @data.key to reference Body Keys, #Content_Type for Headers and .KEY for Variables.

warning

Templating using the Authorization header results in a redacted string.
