# Update a content type

Updates a content type with a specific ID. {% admonition type="info" name="Note" %} The Update method replaces the existing content type with the request body. It does not merge content. Therefore, your request must include the new version of the content type, including both updates and any data you want to retain. Anything not included in your request will be lost. {% /admonition %}
