User content

End users can add their own contents in the form of community posts, post comments, or article comments. Collectively, this is called user content. The format of user content is HTML-based.

Content may contain the following standard HTML tags:

  • Paragraphs and blocks: <p>, <div>, <span>, <br>
  • Text formatting: <b>, <i>, <u>, <strong>, <em>, <sub>, <sup>
  • Links and dividers: <a>, <hr>
  • Images: <img> (where the src attribute has to reference a user-uploaded image)
  • Headers: <h1>, <h2>, <h3>, <h4>, <h5>, <h6>
  • Bullet lists: <ul>, <ol>, <li>
  • Description lists: <dl>, <dt>, <dd>
  • Tables: <table>, <thead>, <tbody>, <tfoot>, <tr>, <th>, <td>, <colgroup>, <col>
  • Quotes and code snippets: <blockquote>, <pre>
  • Semantics: <abbr>, <acronym>, <cite>, <code>, <tt>, <samp>, <kbd>, <var>, <dfn>, <address>

In addition, the content may contain these non-standard HTML tags:

  • @mentions: <x-zendesk-user>, where the contents of the tag should be the user ID of the mentioned user. Example: <x-zendesk-user>1234</x-zendesk-user> to mention the user whose ID is 1234.

Even if the content is validated, the body that's output may not be identical to the request body. For example, adjustments may be made for security or standards-compliance reasons.

{  "author_id": 3465,  "body": "Thanks for your help!",  "created_at": "2012-04-04T09:14:57Z",  "id": 1635,  "locale": "en-us",  "source_id": 65466,  "source_type": "Article"}

{  "comment": {    "author_id": 89567,    "body": "Good info!",    "id": 35467,    "locale": "en"  }}

Create Comment

  • POST /api/v2/help_center/{locale}/articles/{article_id}/comments
  • POST /api/v2/help_center/articles/{article_id}/comments

Adds a comment to the specified article. Because comments are associated with a specific article translation, or locale, you must specify a locale.

Allowed for

  • End users

Agents with the Help Center manager role can optionally supply a created_at as part of the comment object. If not provided, created_at is set to the current time.

Supplying a notify_subscribers property with a value of false will prevent subscribers to the comment's article from receiving a comment creation email notification. This can be helpful when creating many comments at a time. Specify the property in the root of the JSON object, not in the "comment" object.
