# Templates
Treezor uses the Twig 3.x templating engine (opens new window).
Like other files, templates should be base64 encoded.
# Twig Basics
A template is a file that contains both structure (sometime also styling) and instructions to inject content within. Such as: "display this variable or something else if the variable is unavailable", "iterate on this array", etc.
Information – Treezor implementation of Twig has the following limitations
- Layouts and Blocks are unavailable
- Variables are limited to those Treezor provide
- CSS styling must be inlined (
<a style="color:orange;">my link</a>or within a<style type="text/css"></style>in the page's<head>)
# Emails templates
Your Email templates must produce HTML, an additionnal template producing TXT is also required. This TXT atlternative is dedicated to clients that don't support HTML such as screen readers for the visually impaired.

# Checking supported endpoints
Not all Treezor endpoints support templates. To check out which endpoints can be templated, you can use the following request.
Returns the complete list of customizable templates.
# Listing available variables
To retrieve the list of variables available within a template, you can use the following request.
Returns the details about the template, including a list of accessible variables (variables).
If you attempt to use an non-existent variable, an error is returned.
# Uploading a template
All templates must be uploaded to the following endpoint PUT {baseUrl}/customization/templates/{templateName}/template, where the endpointName URL parameter corresponds to the endpoint to which you want to apply this template.
Your base64 encoded template should not contain line break (\n)
