Key concepts

Profile Groups and Placements

PostProxy organizes profiles into Profile Groups (e.g. per brand or client). When creating a post, select a Profile Group first, then pick individual profiles from that group.

For Facebook, LinkedIn, Google Business, and Telegram, you also need to select a Placement (page, organization, channel) from the Placements section of the Post › Create node.

Direct Messages

DM support covers Facebook Messenger, Instagram, Telegram, and Bluesky. Use DM Chat to manage conversations and DM Message to send and receive messages.

Telegram DMs support reply_markup (inline keyboards) — pass it as JSON in Additional Fields when sending a message.

Webhooks

Subscribe to events like comment.created, message.received, platform_post.published, and more. Point the webhook URL at an n8n Webhook trigger node to build real-time automation.
