Direct messages: chats, private replies, and ig.me referrals via API
Postproxy now reads and sends 1:1 direct messages on Facebook Messenger, Instagram, Telegram, and Bluesky — including private replies that turn a comment into a DM and ig.me / m.me link referrals with campaign attribution.
Profile stats: follower and engagement timeseries via API
Postproxy now records follower counts and engagement metrics for every connected profile across all ten networks, exposed as a unified timeseries endpoint.
Google Business Profile support added to Postproxy
Postproxy now publishes local posts to Google Business Profile locations and replies to reviews — three post formats and review management behind the same posts API.
Telegram and Bluesky added to Postproxy
Postproxy now publishes to Telegram channels via your own bot and to Bluesky via app password — both behind the same posts API as the other eight platforms.
New Postproxy pricing, and why
Scale moves to $99/mo and Enterprise to $699/mo for new subscriptions starting May 7. Existing customers keep their current price. Here's what changed and the stories behind the decision.
Making errors actually useful
Why Postproxy stopped translating platform errors and started propagating them raw, with hints when they need one.
Salesforce went headless. Social media is next.
Salesforce Headless 360 turns the platform into APIs, MCP tools, and CLI commands. Postproxy runs the same pattern for social media publishing.
