Is PostZen broader than Upload-Post?

No. Upload-Post markets more platforms and adjacent API capabilities. PostZen focuses on its documented publishing workflow.

Can PostZen upload videos?

PostZen supports media items through public URLs and a media presign endpoint. Platform-specific media requirements still apply.

Can PostZen post to multiple platforms at once?

Yes. The /v1/posts API accepts an array of platform targets, each with its own accountId and optional custom content.

Who should choose Upload-Post?

Choose Upload-Post when its broader platform coverage, SDKs, automation templates, or analytics scope are the deciding factors.

The Upload-Post Alternative for product-native workflows

Upload-Post markets a broad one-call social posting API for TikTok, Instagram, YouTube, and more. PostZen uses a product REST flow: connect accounts, upload media, target platforms, and schedule posts.

// Simple API key authentication
fetch('https://api.postzen.dev/v1/posts', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer POSTZEN_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    platforms: ['instagram', 'twitter', 'linkedin'],
    content: 'Hello world!'
  })
})

Both are API-led. The workflow shape is different.

Upload-Post emphasizes one API call, SDKs, automation platforms, analytics, and white-label posting. PostZen uses a smaller set of public endpoints that fit into your own product model.

WHY POSTZEN

A structured API for embedded products

PostZen is useful when your product has real users, connected accounts, and scheduled content records that need stable platform targets.

Explicit account targets

Draft or schedule

Use isDraft, publishNow, or scheduledFor depending on your product state.

Media as a first-class step

Presign uploads and pass PostZen-hosted media URLs into the post request.
