Reply to a comment, i.e. comment on a comment, on either an Ayrshare made comment, using the [Ayrshare Comment ID](/apis/comments/overview#comments-with-ayrshare-comment-id), or a comment made outside of Ayrshare, using the [Social Comment ID](/apis/comments/overview#comments-with-social-comment-id).

Most often, you will reply to a comment made through Ayrshare, but when you want to reply to a comment made outside of Ayrshare, you can use the Social Comment ID, which you get [GET /comment](/apis/comments/get-comments) endpoint.

Supported platforms: Bluesky, Facebook, Instagram, LinkedIn, TikTok, X, and YouTube.

## Header Parameters

<HeaderAPI />

## Path Parameters

<ParamField body="commentId" type="string" required>
  If replying to a comment made through Ayrshare, use the [Ayrshare Comment ID](/apis/comments/overview#comments-with-ayrshare-comment-id) `commentId` returned from the [POST comment endpoint](/apis/comments/post-comment).

  For example, the Ayrshare comment ID `commentId` returned from the [POST comment endpoint](/apis/comments/post-comment) is:

  ```json Ayrshare Comment ID Returned from POST /comment theme={"system"}

  }
  ```

  If replying to a comment made outside of Ayrshare, use the [Social Comment ID](/apis/comments/overview#comments-with-social-comment-id) `commentId` from the social network.

  For example, the social comment ID `commentId` returned from a Facebook [POST /comment](/apis/comments/post-comment) or [GET /comment](/apis/comments/get-comments) endpoint is:

  ```json Social Comment ID Returned from POST /comment theme={"system"}
  {
    "facebook": { "commentId": "8392829334_1234567890" }
  }
  ```
</ParamField>
