Comments

Ids

A post id is {pageId}_{postId}. A comment id from a webhook is {postId}_{commentId}.
Post ids come from comment webhook events or from your post list.

List comments

curl "https://gateway.hookmyapp.com/meta/v25.0/${POST_ID}/comments?fields=id,from,message,created_time,is_hidden,parent&filter=stream" \
  -H "Authorization: Bearer ${PAGE_ACCESS_TOKEN}"

filter=stream returns every comment, replies included, oldest first. A reply carries parent.id.
Results are paginated with paging.cursors.after.

Reply publicly

Posts a reply under the comment.

curl -X POST "https://gateway.hookmyapp.com/meta/v25.0/${COMMENT_ID}/comments" \
  -H "Authorization: Bearer ${PAGE_ACCESS_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{ "message": "Thanks!" }'

Hidden or deleted comments cannot be replied to. Unhide first.

Reply privately

Sends a Messenger message to the commenter instead of a public reply.

curl -X POST "https://gateway.hookmyapp.com/meta/v25.0/${PAGE_ID}/messages" \
  -H "Authorization: Bearer ${PAGE_ACCESS_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
  "recipient": { "comment_id": "500000000000001_500000000000002" },
  "message": { "text": "Sent you the details here." }
}'

Private replies have hard limits from Meta:
One private reply per comment.
Within 7 days of the comment.

A rejected private reply is permanent for that comment. Retrying the same call cannot succeed.
The person’s reply, if any, opens a normal 24-hour window.

Hide, unhide and delete

# Hide a comment (unhide with is_hidden=false)
curl -X POST "https://gateway.hookmyapp.com/meta/v25.0/${COMMENT_ID}" \
  -H "Authorization: Bearer ${PAGE_ACCESS_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{ "is_hidden": true }'

# Delete a comment. Use the numeric comment id (the part after the underscore)
curl -X DELETE "https://gateway.hookmyapp.com/meta/v25.0/${NUMERIC_COMMENT_ID}" \
  -H "Authorization: Bearer ${PAGE_ACCESS_TOKEN}"

Hidden comments stay visible to their author and their friends. Delete is irreversible and only works on comments on the Page’s own posts.

Moderate with the CLI

# List comments
hookmyapp facebook comments list --channel ch_xxxxxxxx --post <page-id>_<post-id>

# Reply to a comment
hookmyapp facebook comments reply --channel ch_xxxxxxxx --comment <comment-id> --message "Thanks!"

# Send a private reply
hookmyapp facebook comments private-reply --channel ch_xxxxxxxx --comment <comment-id> --message "Sent you a DM"

# Hide and unhide
hookmyapp facebook comments hide --channel ch_xxxxxxxx --comment <comment-id>
hookmyapp facebook comments unhide --channel ch_xxxxxxxx --comment <comment-id>

# Delete
hookmyapp facebook comments delete --channel ch_xxxxxxxx --comment <comment-id>

The CLI accepts either comment id form and picks the right one for each call.

Moderate with MCP

Three tools cover comments: list_facebook_comments, reply_facebook_comment (public, or private with private: true) and moderate_facebook_comment (hide, unhide or delete).

Use HookMyApp MCP to list the comments on my latest Facebook post, reply to genuine questions, and hide spam.
