Options

Key	Type	What it does
`link`	url	Shows a link preview card under the post. A post with a link preview cannot have files.

Facebook builds the card from the page itself. The URL is not added to your text, so type it in content too if you want it to show there.

Example

{
  "channelId": "CHANNEL_FACEBOOK",
  "options": { "link": "https://example.com/launch" },
  "blocks": [{ "content": "We're live! Read the full story." }]
}

Good to know

Facebook and Instagram are set up from the same Meta app in Platform apps.

Comments

You can read the comments on a published post and reply to them as the Page. See Read and reply to comments.

Newest first, 25 comments per page, each with up to 25 of its replies. Use nextCursor for more.
Your own extra blocks (the comments Bulkit posted for you) are not listed.
Facebook hides some commenters' names from apps. Those show as "Facebook user". You can still reply to them.
Needs pages_read_engagement and pages_manage_engagement on your Meta app. Bulkit already asks for both when you connect a Page.

Set up

To connect accounts, you first need your own app on this platform. See the Facebook Page app setup guide.
