WHY POSTZEN?

PostZen vs. Meta Threads API

Meta Threads API brings its own authentication, rate limits, media rules, and maintenance. PostZen replaces it with one predictable integration.

Threads native workflow

  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',

Frequently asked questions

Still have questions?

How do I connect a Threads account?

Threads uses Instagram Business account authentication. Connect your Instagram Business account through PostZen's dashboard, and you'll automatically get access to post to Threads as well.

What's the character limit for Threads?

Threads has a 500 character limit per post. PostZen automatically validates content length and will warn if your content exceeds the limit.

Can I create Threads conversations?

Not yet. Each API call publishes a single Threads post today. Threaded conversations are on our roadmap.

Can I schedule Threads posts with other platforms?

Absolutely. PostZen's unified API lets you post to Threads alongside TikTok, Instagram, Facebook, YouTube, LinkedIn, X, and other supported platforms in a single API call.

What media can I attach to Threads posts?

Threads supports images and videos. You can attach multiple images or a single video per post. PostZen automatically optimizes media for Threads' requirements and handles the upload process.
