Threads finally has a real API
Meta's official Threads API lets approved apps publish text, image and video posts to your Threads profile after you authorize them with your Threads account. Tokens are long-lived (about 60 days) and refresh automatically.
How publishing works under the hood
Threads uses a two-step container flow: the app creates a media container (with your text and an image or video URL), waits for Meta to process it, then publishes it. SparkSocialHq handles the whole dance — including polling video containers until they're ready.
- ✓ 500 characters per post
- ✓ One image (JPEG/PNG) or one video per post
- ✓ Posts appear on your profile like any native post
Threads + everywhere else
Threads culture rewards conversational, X-like brevity. Auto-Adapt trims your master caption to 500 characters automatically, while the same post goes out full-length on LinkedIn and title-first on Reddit. Write once; every network gets its native shape.
