# Templating language
To create dynamic templates that can be used directly in our backend we use Go:s built-in templating language. Below is a brief description of the syntax.
# Basic syntax
Some variables as described below can be included in messages templates and
other config parameters. The template string uses double {{}} brackets with
the path to the variable from the root object denoted with a dot (.).
Example
Your {{.installation.Name}} reported a temperature of {{.payload.value}}{{.payload.unit}}.
Using this template on an installation named "Summer house" with parameters
value (24.5 )and unit (°C) in the POST data will result in a message like
the following.
Your Summer house reported a temperature of 24.5°C
More details about Golang Templating can be found in their documentation (opens new window).
