Field Details
BestCommentId
Type
reference
Properties
Filter, Group, Nillable, Sort
Description
The ID of the comment marked as best answer on a question post.
Body
Type
textarea
Properties
Nillable, Sort
Description
The body of the feed item. Required when Type is TextPost or AdvancedTextPost. Optional when Type is ContentPost or LinkPost.
Although a value for Body is not required for the ContentPost type, an attachment is required. If an attachment isn’t present, the type changes to TextPost or AdvancedTextPost, depending on the API version. TextPost and AdvancedTextPost do require a value for Body.
Tip

Tip

See the IsRichText field for a list of HTML tags supported in the body of rich text posts.
CommentCount
Type
int
Properties
Filter, Group, Sort
Description
The number of comments associated with this feed item.
Tip

Tip

In a feed that supports pre-moderation, CommentCount isn’t updated until a comment is published. For example, say that you comment on a post that already has one published comment and your comment triggers moderation. Now there are two comments on the post, but the count says there's only one. In a moderated feed, comments aren’t counted until approved by an admin or someone with Can Approve Feed Post and Comment or Modify All Data.

Feed moderation has implications on how you retrieve feed comments. In a moderated feed, rather than retrieving comments by looping through CommentCount, go through pagination until the end of comments is returned.
InsertedById
Type
reference
Properties
Group, Nillable, Sort
Description
ID of the user who added this item to the feed. For example, if an application migrates posts and comments from another application into a feed, the InsertedBy value is set to the ID of the context user.
IsRichText
Type
boolean
Properties
Defaulted on create, Filter, Group, Sort
Description
Indicates whether the feed item Body contains rich text. If you post a rich text feed comment using SOAP API, set IsRichText to true and escape HTML entities from the body. Otherwise, the post is rendered as plain text.

Rich text supports the following HTML tags:

  • <p>
    Tip

    Tip

    Though the <br> tag isn’t supported, you can use <p>&nbsp;</p> to create lines.

  • <a>
  • <b>
  • <code>
  • <i>
  • <u>
  • <s>
  • <ul>
  • <ol>
  • <li>
  • <img>

    The <img> tag is accessible only through the API and must reference files in Salesforce similar to this example: <img src="sfdc://069B0000000omjh"></img>

Note

Note

In API version 35.0 and later, the system replaces special characters in rich text with escaped HTML. In API version 34.0 and prior, all rich text appears as a plain-text representation.
