Twitter/X Long-Form Posts

Unlock the ability to schedule and publish long-form posts (up to 25,000 characters) to Twitter/X using the Publer API—exclusively for accounts with an X Premium subscription.

Overview

Twitter/X supports long-form posts (sometimes called "long posts" or "extended tweets") for users with an X Premium (formerly Twitter Blue) subscription, even at the Basic tier. These posts can contain up to 25,000 characters, far exceeding the standard 280-character limit.

With Publer, you can programmatically schedule and publish long-form posts via the API. Publer automatically detects your account’s eligibility and switches to the appropriate post type.

How It Works

• Accounts with X Premium: You can create and schedule long-form posts up to 25,000 characters.

• Accounts without X Premium: Your post text will be truncated to the standard 280-character limit, and the long-form post type will be disabled.

Tip: Validate the post length in your integration to avoid surprises when publishing.

Key Differences

• Long-form posts are not the same as Twitter threads. Threads are multiple connected posts; long-form posts are a single post with expanded character count.

• Scheduling long-form posts is not possible directly on X/Twitter—use Publer’s API or platform to achieve this functionality.

Request Example

To schedule a Twitter/X long-form post, set the network type to "long_post" inside the details object for the "twitter" network:

{
  "bulk": {
    "state": "scheduled",
    "posts": [
      {
        "networks": {
          "twitter": {
            "type": "status",
            "details": {
              "type": "long_post"
            },
            "text": "This is a twitter long post"
          }
        },
        "accounts": [
          {
            "id": "66e011b94e299eb49376c715",
            "scheduled_at": "2025-09-24T14:16+02:00"
          }
        ]
      }
    ]
  }
}

Important Notes

• X Premium Required: Only X Premium accounts can publish long-form posts. For other accounts, posts will be truncated to 280 characters.

• Not for Threads: Use this format for single extended posts, not for multi-part threads.

• API Detection: Publer automatically detects account eligibility for long-form posting.

• Scheduling Limitation: Twitter/X doesn’t natively support scheduling long-form posts; this is enabled via Publer’s platform and API.

Best Practices

• Check your account’s X Premium status before relying on long-form functionality.

• Always validate post length to ensure your content is not unintentionally truncated.

• Use long-form posts for in-depth announcements, articles, or detailed updates—threads remain better for sequential storytelling.
