Postproxy was a lucky find for us. Claude AI gave us the recommendation. We wanted to create a button click agentic workflow for Seresa to post to 8 or more social video sites. Postproxy punches well above its weight seeing we can also collect view stats and comments — so amazing.
Platform coverage, private replies, interactive messages, and how inbound events are delivered.
01Which platforms support comments and DMs?
Comments are available across Instagram, Facebook, YouTube, Threads, and LinkedIn. Direct messages are available on Facebook, Instagram, Telegram, and Bluesky. Individual actions vary by platform.
02How does a private reply to a comment work?
One POST action sends a DM to the author of an Instagram or Facebook comment and creates or reuses the chat automatically. Meta permits one private reply per comment, up to seven days after the comment.
03Can an automation use the HUMAN_AGENT tag?
No. HUMAN_AGENT is only for a human resolving the participant's own inquiry after the normal 24-hour window. It is not allowed for automated, promotional, or re-engagement messages.
04Where are quick replies, cards, and buttons supported?
Quick replies, buttons, and cards are available on Facebook and Instagram, with combination rules that differ between them. Telegram uses reply_markup keyboards, while Bluesky supports text DMs without interactive templates.
05Do all inbound messages arrive instantly?
Facebook, Instagram, and Telegram deliver live events through platform webhooks. Bluesky is polled about every five minutes, and new messages still produce message.received events after ingestion.
