Yes, passing full HTML strings via the API to be rendered within an HTML-editor template is supported functionality.

How to implement:

Prepare the Template: In your Email Template (created via the HTML Editor), insert a Liquid placeholder where the content should appear, e.g., {{ VAR_NAME }}.
Send the Request: In your /createEmailMessage API call, pass the HTML string using either the content or dynamic_content_placeholders parameter.

Example API Payload:

{
  "request": {
    "notifications": [{
      "dynamic_content_placeholders": {
        "VAR_NAME": "<div>Your injected HTML content here</div>"
      }
    }]
  }
}

The Liquid engine will resolve the placeholder and render the passed HTML string at send time.
