REST API Template

Update a template

PUT /v3/templates/<templateRef>

Updates a template. Every update increases the value in the revision key by one.

Attribute	Type	Description	Example
`templateRef`	string	The reference of the template. If you do not know the template reference, first retrieve templates.	`340ced1b-c9b7-43f0-9eec-2b9f0b7693fa`

At a minimum, you must provide the following required attributes in the request body:

Attribute	Type	Description	Example(s)
`name`	string	The name of the template.	`"Alert bar template"`
`friendlyId`	string	The unique ID of the template. Only lowercase alphanumeric characters and underscores are allowed.	`"alert_bar_template_1"`
`type`	string enum (uppercase)	The type of the template.	Must be one of: `"WEB"` `"DECISION"` `"CONDITION"` `"JS_MODULE"`
`status`	string enum (uppercase)	The current status of the template.	Must be one of: `"DRAFT"` `"PUBLISHED"`
`description`	string	The description of the connection.	`"Alert bar web template"`
`render`	boolean	Determines whether to render a preview of the web template in the Sitecore Personalize app. Only set this to `true` if you're confident that your web template can render. Do not set this to `true` for more sophisticated web templates that use handlebars loops.	`true, false`
`defaultTemplate`	boolean	Determines whether this is a default template. When you create a template, you must set this value to `false`.	`false`
`customTemplate`	boolean	Determines whether this is a custom template. When you create a template, you must set this value to `true`.	`true`
`templateElements` optional	JSON array of JSON objects	Custom HTML, CSS, JavaScript, and FreeMarker codes that define the template.	`"mys3cr3tstr1ingforauth1!x"`

The optional templateElements array of objects lets you include HTML, CSS, JavaScript, and FreeMarker codes in your templates. For the objects in templateElements, use the following attributes:

Attribute	Type	Description	Example(s)
`id`	string enum (lowercase)	The type of code that you include in the `template` attribute. For example, to include CSS code in the template, set this value to `"css"`, then specify the custom CSS code in the `template` attribute.	Must be one of: `"html"` `"css"` `"js"` `"freemarker"`
`template`	string	Stringified HTML, CSS, JavaScript, or FreeMarker code. For FreeMarker code, you must at a minimum include an opening and a closing curly bracket `{}`.	HTML: `"<div id=\"test\">My test div</div>"` CSS: `"#test {text-transform: uppercase}"` JavaScript: `"insertHTMLBefore(\"body\");"` FreeMarker: `"{}"`

Here's an example of the templateElements array of objects:

"templateElements": [
  {
    "id": "html",
    "template": "<div id=\"test\">My test div</div>"
  },
  {
    "id": "css",
    "template": "#test {text-transform: uppercase}"
  },
  {
    "id": "js",
    "template": "insertHTMLBefore(\"body\");\n\nconst testDiv = document.querySelector(\"#test\");\ntestDiv.insertAdjacentHTML(\"afterbegin\", \"<p>Hello from JavaScript</p>\")"
  },
  {
    "id": "freemarker",
    "template": "{}"
