</ParamField>

<ParamField body="comment" type="string" required>
  Text of the new comment to add to the post.
</ParamField>

<ParamField body="searchPlatformId" type="boolean" default={false}>

</ParamField>

<ParamField body="platforms" type="array" required>

  If using an [Ayrshare Post ID](/apis/comments/overview#comments-with-ayrshare-post-id) the supported platforms are: `bluesky`, `facebook`, `instagram`, `linkedin`, `reddit`, `tiktok`, `twitter`, `youtube`.

  If no platforms are specified, the comment will be published to all connected platforms that support comments.

  ```json Post a Comment with the Ayrshare Post ID theme={"system"}

    "comment": "An amazing comment!", // required

      "linkedin",
      "reddit",
      "tiktok",
      "twitter",
      "youtube"
    ]
  }
  ```

  If using a [Social Post ID](/apis/comments/overview#comments-with-social-post-id) the supported platforms are -only one platform allowed at a time : `facebook`, `instagram`, `linkedin`, `tiktok`, `twitter`.

  ```json Post a Comment with the Social Post ID theme={"system"}

    "comment": "An amazing comment!", // required
    "searchPlatformId": true, // required
    // facebook, instagram, linkedin, tiktok, twitter
    "platforms": ["facebook"] // Only specify one platform
  }
  ```
</ParamField>

    "mediaUrls": ["https://img.ayrshare.com/gb.jpg"]
  }
  ```
</ParamField>

## @Mentions in Comments

You can include @mentions directly in the `comment` text string. There is no separate parameter for mentions. Simply add `@handle` in your comment text.

```json Comment with @Mention theme={"system"}
{
  "id": "Ut1fWU6XkqkMayHGnJZ",
  "comment": "Great post @CompanyName! Love this.",
  "platforms": ["linkedin", "twitter", "facebook"]
}
```

<Note>
  **LinkedIn Mentions:** LinkedIn mentions are resolved server-side by Ayrshare. Use the [LinkedIn Search endpoint](/apis/listen/search/linkedin-search) to look up the correct vanity name or member name. For organizations, use `@handle`. For members, use `@vanity_name` or `@[Full Name]`.
</Note>

For detailed mention syntax and limitations per platform, see:

* [Bluesky mentions](/apis/post/social-networks/bluesky#bluesky-mentions)
* [Facebook mentions](/apis/post/social-networks/facebook#facebook-page-mentions)
* [Instagram mentions](/apis/post/social-networks/instagram#instagram-mentions)
* [LinkedIn mentions](/apis/post/social-networks/linkedin#linkedin-mentions)
* [Reddit mentions](/apis/post/social-networks/reddit#reddit-mentions)

* [X/Twitter mentions](/apis/post/social-networks/x-twitter#mentions)
