postproxy-dev Comments API

openapi: 3.2.0
info:
  title: Postproxy Social Media Comments API
  version: '2026-09-21'
  summary: Unified social media API for publishing, comments, direct messages, and reviews.
  description: 'The Postproxy API lets you programmatically create and manage social media posts across Facebook, Instagram, TikTok, LinkedIn, YouTube, X (Twitter), Threads, Pinterest, Bluesky, Telegram, and Google Business. Beyond publishing you can read and reply to comments, read and send direct messages, and reply to Google Business reviews and Facebook Page recommendations.


    Send one payload; Postproxy maps it to each platform''s rules and returns a per-platform outcome. Sandbox mode is included on all plans for development without real accounts.

    ## Versioning and deprecation


    The API has a single stable version served at https://api.postproxy.dev/api. Releases are identified by this document''s date-based `info.version`. Changes are additive: new endpoints, new optional parameters, and new response fields may appear, and clients should ignore fields they do not recognize. Existing fields, parameters, and status codes are not changed or removed without a deprecation cycle.


    When an endpoint or field is deprecated it is marked `deprecated: true` in this specification and announced in the changelog (https://postproxy.dev/getting-started/changelog/) at least 90 days before removal.'
