what you can do

Threads posting from one API

Same PostWing API as the full product, scoped to Threads when you post to a Threads account.

  • Schedule Threads text, image, and video posts
  • Upload media with a direct upload URL
  • Use per-account captions when you need them
  • Schedule in one call; edit or cancel any time before it publishes
  • Edit or cancel scheduled Threads posts from the same API
See Threads platform options

built for Threads

Text and media in one flow

Set a caption, optional media, pick a time, and target Threads. No extra platform options beyond the caption.

  • Images for visual Threads posts
  • Video posts when you need motion
  • Scheduled posts show up on your PostWing calendar

Threads options

Keep it simple

Threads uses caption only. There are no extra options.

  • Clear errors with a code and the exact field to fix
  • API key or OAuth with scoped access

one API

Same API for every network

There is no separate Threads product. List more account ids in accounts on the same call. Add Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, or Threads without changing your integration.

  • Instagram
  • Facebook
  • Threads
  • YouTube
  • Pinterest
  • LinkedIn
  • TikTok
  • X (Twitter)

Connect accounts once in PostWing (or via the accounts endpoints)

Call POST /posts with every account you want on that post

It is on your calendar. One key covers every platform PostWing supports.
